PUSH BUTTON

PT100 TX

1.0 DESCRIPTION

The TX12 head mounted temperature transmitter connects to any standard pt100

resistance sensor and converts the linearised temperature to a (4 to 20) mA signal. The

transmitter is a two wire device, and is fully configurable by the user, over a wide

temperature range, with the aid of a simple push button. This new TX12 design

incorporates additional configuration menus, allowing the user to push button trim the

transmitter output at both zero and span, ideal for trimming out sensor errors. The

transmitters advanced circuitry guaranties high stability over the wide operating ambient

temperature ranges experienced by head mounted devices.

One of the transmitters features is the program LED, which provides visual indication of

sensor fault when in normal operation and is also used to guide the operator through the

simple menus during configuration.

2.0 RECEIVING AND UNPACKING

Please inspect the packaging and instrument thoroughly for any signs of transit damage.

4.1 Mechanical

The TX12 transmitter has been specifically designed to fit inside a DIN standard probe

head enclosure (such as the Omega NB series), which provides adequate protection

from moisture, dust, corrosive atmosphere etc. All cable entries must be sealed using the

correct size gland. Likewise any probe assembly fitted must be sealed.

Care must be taken when locating the transmitter to ensure the working ambient

temperature range of (-40 to 85) °C is not exceeded. The TX12 enclosure has a centre

hole allowing the sensor wired to enter screw terminals from the transmitter centre, this is

applicable when the sensor is mounted directly below the transmitter.

4.2 Electrical

Electrical connections to the transmitter are made to the screw terminal provided on the

top face. The sensor wires must be equal length and type for the lead compensation to

work correctly. The screw terminals allow for wires to enter either inner or outer direction.

The transmitter is protected against reverse connection and over voltage. If no sensor

(input) connection is made the transmitter will go into either up or down scale output

current, depending on configuration.

Figure 2 gives connection details, the output is shown connected to a 24 V supply. The

load symbol represent any other device connected in the loop, such as Monitoring

equipment , panel indicators and loop isolators. The load value can range from 0 ohms to

the max loop load for given supply, refer to section 3 “Max load” for more information.

The transmitter conforms with EC directive BS EN 61326 : 1998 when correctly installed

in a termination head providing at least IP20 protection and with sensor wires less than 3

metres. Screened or twisted pair wires are recommended for output wires. Always ensure

the (4 to 20 ) mA loop is grounded at one point, this would normally be at the monitoring
