1.5 General Description & System Components

1.5.1 General Description

Introduction

Your Wireless Thermocouple/Connector Series features stand-alone, compact, battery powered wireless connectors that transmit their readings back to a host receiver up to 90 m (300’) away. Each thermocouple unit is factory set to work as a type J, K, T, E, R, S, B, N or C calibration connector. When activated the connector will transmit readings continuously at a pre-set time interval that was programmed by the user during the initial setup. Each unit measures and transmits: Process Input Reading, Connector Ambient Temperature, RF Signal Strength and Battery Condition to the host and is displayed on the PC screen in real time using the provided software. When used with host receiver model MWTC-REC1 data from up to 48 wireless connectors can be received and displayed. Each unit includes free software that converts your PC into a strip chart recorder or data logger so readings can be saved and later printed or

exportedtoaspreadsheetle.

MWTC-D is a wireless thermocouple connector/data logger. It can record up to 65400 process temperature data points or 32,700 process and ambient temperature data points locally. The recorded data can be downloaded to PC using the direct USB connection.

4.1.2 Congure Your Connector/Transmitter

Now that you have connected your USB cable to your PC and connector

transmitteryouwillcompletethefollowingstepstocongureyourconnector/

transmitter before placing the unit into operation. You will be using the

congurationsoftwareutilitythatyouinstalledontoyourPCinSection3.2.If youhavenotinstalledthecongurationsoftwareutilityyoushoulddosonow.

During this procedure you will be setting the following parameters in your connector transmitter.

Address Number This sets a unique address number into your connector/transmitter. Later, when you set up your measurement software you will again set channel numbers to receive readings from the corresponding unit(s). Each connector must be set for

adierentaddressnumberforyoursystemtooperatecorrectly.

NOTE:

If you will be using more than one receiver unit in your area it is important to set the connector/transmitter address numbers to be a corresponding number in your TC-Central software. See Examples below. For the ﬁrst receiver: Set the addresses on your connector/transmitters to 101, 102, 103, 104, etc. Then set the channels in your TC-Central user software to match. For the second receiver: Set the addresses on your connector/transmitters to 201, 202, 203, 204, etc. Then set the channels in your TC-Central user software to match. This numbering scheme can be expanded to match the number of receivers you are using. In addition RF Channel Frequency should be different, between 1st and 2nd receivers.

4-3

Sample Rate (Recording Interval) This will program your device to transmit 1 data reading to your receiver at a

speciedtimeinterval.Availablesettingsare2,3,4,5,10,15,30,45,60,75,90

105, or 120 seconds. The same sampling rate is used for recording interval on MWTC-D.

RF Channel You can set RF Channel Frequency between Channels A, B, C.

Channel Logging Option For MWTC-D you can set additional parameters for data logging option.

NOTE:

The sample rate you set will have the most direct effect on the life of the battery in your connector/transmitter. It is recommended that you set the longest sample time that your application can live with to extend time between battery replacement. See Section 6 for more information on battery life.

STEP 1. Enter the “SETUP” mode.

4.2.3 Installation

When installing your connector/transmitter it is important to position your device in such a way as to optimize the antenna location within what’s known as the “Fresnel Zone”.

The Fresnel Zone can be thought of as a football-shaped invisible tunnel between two locations that provides a path for RF signals between your connector/ transmitter and your receiver.

MWTC

PRESS

SETUP

I / O

FRESNEL ZONE

Figure 4-14. Fresnel Zone

ANTENNA

Page 41

Connector Operation

In order to achieve maximum range, the football-shaped path in which radio waves travel must be free of all obstructions. Obstacles in the path (especially metal) will decrease the communication range between your connector/

transmitterandreceiver.Also,Iftheantennasaremountedjustbarelyothe

ground, over half of the Fresnel zone ends up being obstructed by the earth

resultinginsignicantreductioninrange.Toavoidthisproblem,theantennas shouldbemountedhighenoughoofthegroundsothattheearthdoesnot

interfere with the central diameter of the Fresnel zone.

NOTE:

It is important to understand that the environment may change over time due to new equipment or machinery being installed, building construction, etc. If new obstacles exist between your connector/transmitter and receiver, the devices can be raised on one end or on both ends to hopefully clear the Fresnel Zone of obstructions.

NOTE:

No co-location with other radio transmitters is allowed. By deﬁnition, co-location is when another radio device or it’s antenna is located within 20 cm of your connector/ transmitter and can transmit simultaneously with your MWTC unit. Never install MWTC connector/transmitters within 20 cm or less from each other.

4.2.4 Antenna

NOTE:

Use of any other antenna then what’s supplied with your device will void all FCC and CE regulatory compliance.

Section 6 - System Operation

6.1 Introduction

Compared to wired thermocouple systems, wireless thermocouple systems provide much simpler installation. Based on the physical principle of the propagation of radio waves, certain basic conditions should be observed. The following simple recommendations are provided to insure proper installation and correct operation of your MWTC Series system.

6.2 RF Communication Basics

The Model MWTC wireless Thermocouple Connector/Transmitter sends wireless transmissions to the MWTC-REC1, MWTC-REC5, or MWTC-REC6 receiver. The receiver checks the incoming data for accuracy and processes this data for use by the measurement software on your PC. Radio signals are electromagnetic waves, hence the signal becomes weaker the further it travels. While radio waves can penetrate some solid materials like a wall, they are dampened more than when a direct line-of-sight between the transmitting and receiving antenna exist.

System Operation

6.3 Basic System Overview

The MWTC wireless thermocouple system is comprised of only two main components; a Thermocouple Connector with a built-in battery powered radio transmitter, and a USB powered radio receiver.

6.4.2 Ambient Temperature Readings

The ambient temperature reading displayed on your screen when running the TC-Central program, is the actual ambient temperature that your connector/ transmitter is being exposed to. This reading is only provided as reference and to aid you in proper installation of your unit. The ambient temperature reading will blink and change to RED digits to alert you that your have exceed the maximum recommended safe operating conditions for your connector/transmitter. You should not rely on this feature as sole protection. Additional protection should be taken by you “the user” to protect your unit from extreme conditions.

NOTE:

Operating your connector/transmitter outside the speciﬁed ambient conditions listed in Section 9 of this manual may cause your unit to malfunction and stop working correctly.

6-2

6.4.3 Indicator Lights

Transmit (TX) Green Indicator Light

①

The green indicator light marked “TX” on the front of the connector/transmitter will blink every time the unit sends data to the receiving unit. Example; If you selected a 5 sec sample rate the green TX led will blink one time every 5 seconds.

Low Battery (Low Bat) Red Indicator Light

②

The red indicator light marked “Low Bat” on the front of the connector/ transmitter will blink when the battery voltage reaches a level at or below the power level required for normal operation. When this indicator turns on it’s time to install a fresh battery in your unit. For procedures on how to change your battery see Section 4.5. For information on battery life see Section 6.11. (See diagram on next page)

Page 49

System Operation

If the red LED blinks twice or is out of sequence from the green LED, it is an indication of an open thermocouple input (MWTC-D).

On the MWTC-D, when turning on the unit, if the red LED blinks once, it means record only. If the red LED blinks twice, it means record & wireless together. If the red LED does not blink, it means wireless only.

6.6 Environment/Operating Conditions

6.6.1 Environment

Omega’s MWTC series connector/transmitter and receiver unit has been

designedtobexedmountedandoperatedinacleananddryindoor

environment. Care should be taken to prevent the components of your wireless system from being exposed to moisture, toxic chemicals and extreme cold or hot

temperaturethatareoutsidethespecicationslistedinthismanual.

6.6.2 Operating Conditions

The following is a list of basic good practice you should apply when operating your wireless system.

• Never operate your wireless device outside the recommended

environmentallimitsspeciedinthismanual.

 •Neveroperateyourwirelessdeviceinammableorexplosive

environments.

• Never use your wireless device in medical, nuclear or other dangerous applications were failure can cause damage or harm.

• Never operate your transmitter/connector with any other battery or power

sourcethanwhat’sspeciedinthismanualoronthebatterycompartment

label.

 •Noco-locationwithotherradiotransmittersisallowed.Bydenition,

co-location is when another radio device or it’s antenna is located within 20 cm of your connector/transmitter and can transmit simultaneously with your MWTC unit.

• Never install a connector/transmitters within 20 cm or less from each other.

• Never use your connector/transmitter as a portable device. Your unit has been designed to be operated in a permanent installation.

• Never install and/or operate your connector transmitter closer than 20 cm to nearby persons.

• Never operate your connector transmitter with any other antenna than what is supplied or listed here in this manual for approved use.

6.7 Determining and Maximizing Range

The available maximum range speciﬁed for the wireless Series system in this manual is only achievable under optimum installation conditions. Mounting height, obstructions in your “Fresnel Zone” and ambient conditions can cause a decrease in signal strength resulting in a shorter range between your transmitter/connector and receiver unit.

The following recommendations will help to improve the range of your wireless system.

Position your receiver in a central location

When multiple connector/transmitters are in operation, position your receiver unit in a central space if possible in equal distance to each connector transmitter.

Test your system before permanent mounting

Before permanently mounting your connector/transmitters in your application

trymovingthedevicestodierentlocationsandmountinganglestodetermine

what installation achieves the best signal strength.

Move your system components higher o the oor and away from exterior walls

Avoidinstallingyoursystemcomponentstoclosetotheoorornearyour

buildings exterior walls. The closer your connector/transmitter and receiver unit are the greater the interference and lose of signal strength will be.

Maintain a line of sight (LOS) between antennas

Maintaining a line of sight between your connector/transmitter and receiver unit will produce greatly improved signal strength over a system were the antenna’s in your system have obstacles blocking them.

Maintain a constant ambient temperature environment

Maintaining a constant ambient temperature environment is important to achieving maximum signal strength. Exposing your system components to extreme hold or cold temperatures, or sudden changes in ambient conditions

willhaveaneectontheperformanceofyoursystem.

System Operation

6.7.1 Operation in Buildings

Your Connector/Transmitter sends wireless data transmissions to a receiver connected to your PC. Radio signals are electromagnetic waves. A radio signal

becomesweakerthefurtherittravels.Rangeisdecreasedbydierenttypesof

materials found in the direction of the signals propagation. Radio waves can penetrate most types of wall materials, but they are dampened more than they would be by a direct line-of-sight installation.

6.7.2 Building Materials

Examplesofhowdierenttypesofwallmaterialmayreduceyoursignal:

Material Type Possible Signal Reduction

Wood, Plaster, Sheetrock, Uncoated 0 to 10% Glass w/o Metal, Fiberglass

Brick, Pressboard 5 to 35%

Reinforced Concrete 10 to 90%

Metal Walls, Metal Doors, Elevators, Metal Stair Cases, Metal Piping, 90 to 100% Metal Mesh, Metal Screening

Figure 6-6. Operation In Buildings

Avoid dampening materials by repositions the connector/transmitting and/or receiver.

6.7.3. Penetration Angle of Radio Waves Through Walls

The angle at which the transmitted radio signal hits a wall is very important

andalsohasabigeectonmaximizingrange.Signalsbetweenyourconnector/

transmitter should be transmitted as directly as possible.

6-6

6.8 Antenna Basics

6.8.1 Antenna Basics

Bydenition,anantennaisadeviceusedtotransformanRIsignal,travelingon

a conductor, into an electromagnetic wave in free space. Antennas demonstrate a property known as reciprocity, this means that an antenna will always maintain the same characteristics regardless if it is used to transmit or receive.

Mostantennasareresonantdevices,whichmeanstheyoperateecientlyover

a relatively very narrow frequency band. An antenna must be tuned to the same frequency band of the radio system to which it is connected, otherwise the reception and the transmission will be impaired. The antennas in your wireless thermocouple connector system have been tuned to operate in the 915 or 868 band.

6.9 Antenna Placement

Proper antenna installation is important and will allow you to achieve maximum performance and range between your connector/transmitter and receiver unit.

NOTE:

System Operation

Your connector/transmitter should not be installed on the same side of the wall as the receiver. If mounted close to each other on the same wall, the radio waves are likely to be subject to interfering dispersions or reﬂections. The best positioning is to have the connector/transmitter installed on the opposite or connecting wall to the receiver.

6.9.2 Vertical Antenna Placement

If your Connector/Transmitter is mounded in a vertical position in your application you should mount your receiving so that the same polarization is achieved with the receiving antenna. As shown in the “Vertical” example Fig 6-8.

6.10 Factory Preset Values

Your Connector/Transmitter has been factory programmed for the following default operation; Channel Number: 1, Thermocouple Type: By model number, Transmit Rate: 1 sample/5 sec

6.11 Transmit Rate vs. Battery Life

Many factors such as ambient temperature conditions and transmitting rate can have a

bigeectonthelifeofthebatteryusedinyour

connector/transmitter. Transmitting data places a big demand of the battery in your connector/ transmitter. The transmit rate is the single most contributing factor in the life of your battery. The slower the transmit rate you set, the longer the battery in your device will last. The table below give some estimates on how long the battery should last vs. the transmit rate you selected when you setup your connector/transmitters and under normal operating conditions.
