1. Intended use
The PD111 is a pressure transmitter with internal diaphragm made of stainless steel AISI
316L and with a silicon measuring cell. The transmitter is applied for gauge pressure
measurement in liquid and gaseous media compatible with stainless steel AISI 316L /
1.4435 (AISI 304L / 1.4307). The pressure is converted into an electrical signal 4-20mA.
Restrictions on process medium:
– process medium may not corrode the wetted parts of the transmitter
– process medium may not crystallize or harden in process connection
– process medium temperature must be between -40 and +100 °C
The pressure transmitters described in this guide may be operated only in explosion proof
areas without aggressive vapors and gases.

4. Wiring
The transmitter is connected in accordance with the wiring diagram (Fig. 4.1) considering
the load resistance requirements.
►
NOTICE Signal cables should be routed separately or screened from the supply cables.
►
NOTICE Only a shielded cable may be used for the signal lines.
Fig. 4.1 Wiring diagram
Use the diagram (Fig. 4.2) to select the permissible load resistance.
Recommendation:
U = 24 ± 2 V
R = 500 ± 50 ohm
Fig. 4.2 Load diagram
►
NOTICE
Switch on the power supply only after the wiring of the device has been complete-
ly performed.

5. Connector mounting
– Strip approx. 35 mm of the cable and remove approx. 5 mm insulation from each wire
end.
– Loosen the screw 1.
– Lever the terminal holder 5 out of the enclosure 2 using the mounting hole on the seal
6.
– Unscrew the cable fitting 4 and take out the cable seal 3.
– Lead the cable through the cable fitting 4 and the cable seal 3 in the enclosure 2.
►
NOTICE
Inproper mounting.
Enclosure seal can become damaged.
Do not push the terminal holder 5 out using the screw hole or the cable fitting 4.
– Unscrew the cable fitting 4 and take out the cable seal 3.
– Lead the cable through the cable fitting 4 and the cable seal 3 in the enclosure 2.
– Connect the cable ends in accordance with the wiring diagram (Fig. 4.1).
– Loosen the screw terminals of the terminal holder 5, connect the stripped wire ends in
accordance with the wiring diagram (Fig. 4.1) and screw the screw terminals in tight.
– Put the terminal holder 5 and snap the connector seal 6 in the enclosure 2.
– When screwing the cable fitting 4, make sure the cable fitting 4 with the cable seal
are assembled correctly and the cable seal 3 is not damaged.
– Plug the socket (2+5+6) to the contacts 7.
– Tighten the screw 1.

6. Maintenance and cleaning
The pressure transmitter PD111 is maintenance-free. If needed the housing of the device
can be cleaned using a damp cloth and non-aggressive cleaning solutions, in switched-
off state.
When cleaning the diaphragm, the following is to observe:
−The device may be cleaned only after placing the device out of service correctly.
−The diaphragm can usually be cleaned carefully with a non-aggressive cleaning solu-
tion and a soft brush or sponge.

7. Transport and storage
The device packaging must ensure a shockproof transport and storage. The original
packaging offers an optimal protection.
If the device is not taken into service immediately after delivery, it must be carefully stored
in a safe and protected place.
Storage temperature range: -40...+80 °C.
WARNING
Remove all the adherent media rests on the process connection before storing
the device after operation. This is particularly important if the medium is hazard-
ous to health, e.g. radioactive, carcinogenic, toxic, caustic, etc.
►
NOTICE
The device may have been damaged while shifting.
Check the device for transport damages and completeness!
