1 General Safety Instructions

• Select the appropriate pressure transmitter with regard to scale range, performance and specific measurement conditions prior to installing and

starting the instrument.

Warning

•Observe the relevant national regulations (e.g.: EN 50178, NEC, CEC) and observe the applicable standards and directives for special applications (e.g. with dangerous media such as oxygen, acetylene, flammable gases or liquids and toxic gases or liquids and with refrigeration plants or compressors).

If you do not observe the appropriate regulations, serious injuries and/or damage can occur!

•Open pressure connections only after the system is without pressure!

•Please make sure that the pressure transmitter is only used within the overload threshold limit at all times!

•Observe the ambient and working conditions outlined in chapter 6 "Technical Data"

•Ensure that the pressure transmitter is only operated in accordance with the provisions, i.e. as described in the following instructions.

•Do not interfere with or change the pressure transmitter in any other way than described in these operating instructions...

•Remove the pressure transmitter from service and mark it to prevent it from being used again accidentally, if it becomes damaged or unsafe for operation..

•Take precautions with regard to remaining media in removed pressure transmitter. Remaining media in the prsesure port may be hazardous or toxic!

•Have repairs performed by the manufacturer only.

•Consider the details given in the EC-type examination certificate as well as the respective specifications for explosion hazard use of the country concerned (e.g.: IEC 60079, NEC, CEC). If you do not observe these stipulations, serious injuries and/or damage can occur.

Other important safety guidelines can be found in the different sections of this instruction manual.

Special Intrinsic Safety Instructions

2 Special Intrinsic Safety Instructions

2.1Protection of diaphragm

As soon as the diaphragm of an instrument gets damaged, absolutely no intrinsic safety can be guaranteed any longer! Thus the diaphragm must not come in con- Warning tact with abrasive substances! The diaphragm must be protected against pressure

peaks and must not be touched by tools! Information about material consistency against corrosion and diffusion can be found in our WIKA Handbook, 'Pressure and Temperature Measurement' (German: ISBN 3-9804074-0-3, English: ISBN 3- 9804074-1-1).

2.2Special wiring advice

The housing must always be connected to earth to protect the instrument against electromagnetic fields and electrostatic charges.

Warning The cables and wires must not be damaged.

Cables for applications in Zone 1 and 2 or Zone 21 and 22 must be checked with a test voltage between conductor/earth, conductor/screen, screen/earth of more than 500 V (AC).

Flying leads with fine wires must be covered by an end splice (cable preparation). Both the internal capacity and inductivity must be considered.

Conductive screens may only be connected to earth one-sided and outside the hazardous area.

2.3Connection to Zone 0

(In general Zone 0 is given when the instrument is surrounded by a mixture of

explosive gases more than 1.000 hours per year = continuous hazard. The trans- Warning mitter may only be operated under Zone 0 conditions, as long as an atmospherical

pressure of 0.8 to 1.1 bar is guaranteed). The circuits must be of type Ex ia.

The ingress protection must comply to IP 67 according to IEC 529.

2.4Special precaution for connection to Zone 0 and or Zone 20

Make absolutely sure to follow the advice given in the IEC publication 60 529 for connection to Zone 0 and/or Zone 20 for IP 67 pressure connections!

Warning

Installation in non-metallic vessels:

All metallic parts reaching into Zone 0 and/or Zone 20 must be grounded. The intrinsically safe circuit must be decoupled from the regular circuit.

If the mounting position is less than 1m away from the transition into Zone 0 and/or Zone 20 an overvoltage protection must be integrated. This can either be done within the transmitter (option: overvoltage protection), or outside the transmitter by the customer himself.

Special Intrinsic Safety Instructions

2.5Instructions for temperature ranges

Warning

Observe the permissible surface temperatures applicable for this range according to the defined temperature classes.

Observe the maximum temperature value (of the temperature range defined under item 15.3.4 in the EC type test certificate at the hexagon of the process connection.

Protect the pressure transmitter against touching or affix a warning notice. Insulate heat sources thermally from the pressure transmitter (e.g. pipes or tanks).

2.6Special instructions for dust explosion protection

Warning

Ensure that under hazardous dust environments the pressure transmitter is mounted in a shielded section and protect it against shocks.

When installing the pressure transmitter or the cable gland into areas which require category 1D equipment, ensure that ingress protection IP 6X according to IEC 60 529 is guaranteed.

Observe the EN 50281-1-2 in relation to e.g. dust deposits and temperature.

The permissible ambient temperatures as well as the maximum surface temperatures are to be taken from the EC type test certificate.

Universal IS Pressure Transmitter UniTrans

Product Description

5Product Description

The intrinsically safe pressure transmitter UniTrans can be used in level control applications as well as for pressure measurement applications in process industry. A variety of process connections, measurement ranges, main boards and display options result in a product for a wide range of applications.

5.1Construction

The UniTrans consists of a pressure sensor, a control interface unit and a housing cover with optional display. Due to this modular design, different transmitter versions can be mounted (see “Model Key” on page 151).

Direct Mounted	Processing Unit Housing

5.1.1Pressure Transducer

The pressure transducer has a piezo-resistive or thinfilm measurement cell depending on the pressure range. The sensors are temperature compensated, and have a hermetically welded membrane which is "helium" leak-tested. The pressure transducers do not have internal sealing elements.

Pressure transducers further distinguish themselves from one another based on their pressure ranges and the different materials of wetted parts. Different process connections can be selected to serve a wide range of applications.

Never exceed the overpressure limit of the respective pressure transducer.

Product Description

5.1.2Processing Unit

The processing unit, which is integrated in the housing contains the terminal compartment and the keypad used for programming the transmitter. The four keys must be activated (unlocked) before use. During normal operation the keypad is locked to protect data and functions previously entered. The keypad is automatically locked when no key is hit for 10 minutes. The processing unit converts the digitalized signal from the measuring unit into a standard 4...20 mA current signal.

5.1.3 Display Unit

CALIBRATION

RANGE

The measured-value indicator has four digits (in a 7-segment display) + symbols. Below it, is line 1 (16-segment display) used to display error codes and the signal’s unit of measure. The unit of measure can be selected by the operator. Measurements over 9999 can not be correctly displayed. Please note this when choosing the unit (e.g. 9999 Pascal = 0,09999 bar). Additional information is displayed in lines 2 and 3 (16-segment display). The operator can enter commands in the programming mode on the display unit by means of menu guided, clear-text prompts.

Universal IS Pressure Transmitter UniTrans

Product Description

Transmitters with displays offer a larger number of programming and processing options. These options include alarm status, damping, signal inversion, tank linearization and diagnostic messages.

Display units can be easily upgraded (see chapter 7.2).

5.2Function

The pressure transducer converts the existing pressure into an electrical signal. Microelectronics further process the input signal and produce a proportional 4-20 mA standard signal.

The display-version allows programming (parameterization) and the display of extended functions such as inversion, damping, alarm status and linearization.

	5.2.1 Functions of Transmitters without Displays
	• Calibration of zero and span under pressure (see 8.3)
	• Calibration of zero and span without pressure (dry adjustment) (see 8.4)
	• Setting the dampening / integration of the output signal 0-40 s (see 8.5)
	• Reset to manufacturer’s default values (see 8.6)
	• Mounting correction of the sensor (beginning with software version 1.05, see 8.4.3)
	5.2.2 Functions of Transmitters with Displays
	• Settable units of measurement	(mbar, bar, psi, mA, %, m, mm WS) (see 9.5.1)
	• Volume-related unit of measuring value can be set (l, kg, t, m3, gal, lb) (see 9.5.1)
	• Temperature and Min/Max values shown in display (see 9.5.1)
	• Nominal pressure range of the sensor shown in display (see 9.5.1)
	• Zero and span calibration (with/without pressure) (see 9.5.2)
