1. Important details for your information

Read these operating instructions before installing and starting the pressure transmitter. Keep the operating instructions in a place that is accessible to all users at any time.

The following installation and operating instructions have been compiled by us with great care but it is not feasible to take all possible applications into consideration. These installation and operation instructions should meet the needs of most pressure measurement applications. If questions remain regarding a specific application, you can obtain further information:

Via our Internet address www.wika.de / www.wika.comThe product data sheet is designated as PE 81.47

Contact WIKA for additional technical support (+49) 9372 / 132-295

With special model number, e.g. C-20000, please note specifications in the delivery note.

If the serial number on the product label gets illegible (e.g. by mechanical damage or repainting), the retraceability of the instrument is not possible any more.

WIKA pressure transmitters are carefully designed and manufactured using state-of-the-art technology. Every component undergoes strict quality and environmental inspection before assembly and each instrument is fully tested prior to shipment. Our environmental management system is certified to DIN EN ISO 14001.

Use of the product in accordance with the intended use C-2:

Use the pressure transmitter to transform the pressure into an electrical signal.

Knowledge required

Install and start the pressure transmitter only if you are familiar with the relevant regulations and directives of your country and if you have the qualification required. You have to be acquainted with the rules and regulations on measurement and control technology and electric circuits, since this pressure transmitter is „electrical equipment“ as defined by EN 50178. Depending on the operating conditions of your application you have to have the corresponding knowledge, e.g. of aggressive media.

2. A quick overview for you

If you want to get a quick overview, read Chapters 3, 5, 7 and 10. There you will get some short safety instructions and important information on your product and its starting. Read these chapters in any case.

Notice, important information, malfunction.

The product complies with the applicable European directives.

	The supply current is the measurement signal.
3-wire	Two connection lines are intended for the voltage supply.
	One connection line is intended for the measurement signal.

4. Function

The pressure prevailing within the application is transformed into a standardised electrical signal through the deflection of the diaphragm, which acts on the sensor element with the power supply fed to the transmitter. This electric signal changes in proportion to the pressure and can be evaluated correspondingly.

5. For your safety

	!	Select the appropriate pressure transmitter with regard to scale range,
		performance and specific measurement conditions prior to installing and
	Warning	starting the instrument.
		Observe the relevant national regulations (e.g.: EN 50178) and observe the
		applicable standards and directives for special applications (e.g. with
		dangerous media such as 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!

Screw in or unscrew the instrument only via the flats using a suitable tool and the prescribed torque. The appropriate torque depends on the dimension of the pressure connection. Do not use the case as working surface for screwing in or unscrewing the instrument.

When screwing the transmitter in, ensure that the threads are not jammed.

For tapped holes and welding sockets please see Technical Information IN 00.14 for download at www.wika.de -Service

Electrical connection

Connect the instrument to earth via the pressure connection.

Use power supplies which guarantee reliable electrical isolation of the operating voltage as per IEC/DIN EN 60204-1. Consider also the general requirements for PELV circuits in accordance with IEC/DIN EN 60204-1.

Ingress protection per IEC 60529 (The ingress protection classes specified only apply while the pressure transmitter is connected with female connectors that provide the corresponding ingress protection).

Please make sure that the ends of cables with flying leads do not allow any ingress of moisture.

When mounting the instrument, ensure that the sealing faces of the instrument and the measuring point are clean and undamaged.

Functional test

The output signal must be proportional to the pressure. If not, this might point to a damage of the diaphragm. In that case refer to chapter 9 „Troubleshooting“.

		Open pressure connections only after the system is without pressure!
		Observe the ambient and working conditions outlined in section 7 „Technical
	Warning	data".
		Please make sure that the pressure transmitter is only used within the over-
		load threshold limit at all times!
