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 (data sheets, instructions, etc.) via our Internet address (www.wika.de / www.wika.com ) or contact WIKA for additional technical support (see section7 Starting, Operation/Further information). With special model number, e.g. F-20000 or F-21000, please note specifications in the delivery note. The product data sheet is designated as PE 81.19 WIKA pressure transmitters are carefully designed and manufactured using state-of-the-art technology. Every component undergoes strict quality inspection before assembly and each instrument is fully tested prior to shipment.

Use of the product in accordance with the intended use F-2

Use the pressure transmitter for pressure measurement.

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 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. Get some more detailed information on this product in Chapters 4 Function and accessories and 6 Packaging. Read Chapter 8 for Maintenance. In the case of failures please refer to Chapter 9.

4. Function and accessories

F-20: Standard pressure connection F-21: Pressure connection with flush diaphragm for highly viscous or solids entrained

media which might clog the pressure port.

Function: With the pressure transmitter you measure the pressure of your application, which is trans-formed into an electric signal. This electric signal changes in proportion to the pressure and can be evaluated correspondingly.

Accessories: For details about the accessories, please refer to WIKAs price list, WIKAs product catalog on CD or WIKAs web site www.wika.de. Please refer to our data sheet Pressure gauge sealing washers AC 09.08 in WIKAs product catalog Pressure and Temperature Measurement or our web site www.wika.de for details about sealing washers.

n Select the appropriate pressure transmitter with regard to scale range,

Warning

n Open pressure connections only after the system is without pressure! n Please make sure that the pressure transmitter is only used within the overload

n Observe the ambient and working conditions outlined in section 7 Technical data. n Ensure that the pressure transmitter is only operated in accordance with the provisions

n Do not interfere with or change the pressure transmitter in any other way than

n Remove the pressure transmitter from service and mark it to prevent it from being

n Take precautions with regard to remaining media in removed pressure

n Have repairs performed by the manufacturer only.

n Observe the relevant national safety regulations (e.g.: EN 50178)

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!

6. Packaging

n Inspect the pressure transmitter for possible damage during transportation.

Should there be any obvious damage, inform the transport company and WIKA without delay.

n Keep the packaging, as it offers optimal protection during transportation

(e.g. changing installation location, shipment for repair).

n Keep the protection cap of the pressure connection thread and the diaphragm

for later storage or transport. In order to protect the diaphragm, the pressure connection of the instrument F-21 is provided with a special protection cap.

n Remove this protection cap only just before installing the pressure

transmitter in order to prevent any damage to the diaphragm.

n Ensure that the pressure connection thread and the connection contacts

will not be damaged.

n Mount the protection cap when removing and transporting the instrument.

7. Starting, operation

Has everything been supplied?

Check the scope of supply: n Completely assembled pressure transmitters; with flush version F-21

including pre-assembled sealings and protection cap.

Required tools: wrench (flats 27), screw driver

Diaphragm test for your safety

It is necessary that before starting the pressure transmitter you test the diaphragm, as this is a safety-relevant component.

n Pay attention to any liquid leaking out, for this points to a diaphragm damage. n Check the diaphragm visually for any damage.

Warning

n Use the pressure transmitter only if the diaphragm is undamaged. n Use the pressure transmitter only if it is in a faultless condition as far as the

safety-relevant features are concerned.

n Remove the protection cap only just before installation and absolutely avoid

any damage to the diaphragm during installation as well.

n Ensure that the cable diameter you select fits to the cable gland of the

connector. Ensure that the cable gland of the mounted connector is positioned correctly and that the sealings are available and undamaged. Tighten the threaded connection and check the correct position of the sealings in order to ensure the ingress protection.

n Connect the instrument to earth via the pressure connection and/or

connection terminal 5. n Hold the instrument on the flat of the nut with an appropriate tool and tighten the screws to the required torque or unscrew it as the case may be. Do not hold onto the housing with pliers to screw or unscrew.
