Ultra High Purity Transducer

WU-10: Single End; WU-15: Flow Through; WU-16: Modular Surface Mount
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

6. Packaging

Has everything been supplied?

Check the scope of supply:

 Completely assembled transducer
 Inspect the transducer for possible damage during transportation. Should there be

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

 The transducer is purified, evacuated and double-bagged for clean-room service

and should remain packaged until installation. A protective cap is used to protect the
face sealing beads from nicks or scratches. This plug should remain in place during
storage and handling, in order to prevent damage to the bead. Therefore remove the
inner ESD (Electro-Static Discharge) bag only at the place of installation.

 Keep the packaging, as it offers optimal protection during transportation (e.g. chan-

ging installation location, shipment for repair).

 Ensure that the pressure connection thread and the connection contacts will not be

damaged.

 Remove this protection cap only just before installing the pressure transmitter
 Mount the protection cap when removing and transporting the instrument.

Unpack the transducer

1. Remove the transducer from the box.

2. Remove the outer protective bag and discard.

For version FM-Approved please note the special connection conditions on the enclosed
control drawing.

When designing your plant, take into account that the stated values (e.g.burst pressure,
over pressure safety) apply depending on the material, thread and sealing element used.

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 10 „Troubleshooting“.

 Open pressure connections only after the system is without pressure!
 Observe the ambient and working conditions outlined in section 7

Warning

„Technical data.

 Please make sure that the transducer is only used within the over load

threshold limit at all times!
When touching the transducer, keep in mind that the surfaces of the instru-

ment components might get hot during operation.

Caution

8. Adjustment of zero point

These Transducers are maintenance free.
If a zero offset occurs anyhow, this can be adjusted by means of a built-in potentiometer.

For verification and adjustment of the zero point, vent the transducer to zero (0)PSI for gage
reference transducers. The potentiometer for the zero adjustment is protected inside the trans­ducer housing. Use a 0.040" to 0.060" (1 to 1.5 mm) jeweler's screwdriver for adjustment.

Span adjustment is not necessary after zero point correction.

14

WIKA Operating instructions/Betriebsanleitung/Mode d'emploi/Instrucciones de servicio WU-1X

8. Adjustment of zero point

Procedure for Transducer without Side-Access

1. Remove all power to the transducer.

2. Remove the locking ring, on the top of transducer, in order to expose
the zero adjusting potentiometer. Carefully pull the assembly out of the
transducer housing, as far as the internal connector cable will allow.

3. Restore power to the transducer.

4. Vent the transducer to pressureless state. Monitor the output signal,
and adjust the zero screw to 4mA or 0.1V depending on the signal
output. The Zero adjustment screws are both turned in a clockwise
direction to increase the signal or in a counter clock-wise direction to
decrease the signal.

5. Remove all power to the transducer again.

6. Rotate the electrical connector on the transducer housing to
the keyed insertion. After this, replace and hand tighten the
locking ring on the top of transducer.

Procedure for Transducer with Side-Access

1. Turn the grip ring until the access to the
potentiometer is free.

2. Adjust the zero point by means of the
potentiometer in pressureless state.
When doing this, do not contact other
components with the screw driver to
excluse a short circuit in the instrument.
Check the zero point by means of a
suitable instrument. Clockwise rotation
means an upward zero offset,
anti-clockwise rotation means a down
ward zero offset.

3. After this, turn the grip screw until the
access to the potentiometer is closed
