Frequently Asked Questions - PX9134 IFM

What is the power supply voltage for the IFM PX9134?

The power supply voltage is 24 VDC.

How do I connect the sensor to a PLC?

Connect the output signal (4-20 mA or IO-Link) to the analog input of your PLC. Refer to the manual for wiring diagrams.

What is the output signal of the PX9134?

The output signal is 4-20 mA analog or IO-Link digital.

Is the sensor suitable for wet environments?

Yes, it has IP67 protection, meaning it is dust-tight and can withstand temporary submersion.

How should I clean the sensor?

Clean with a dry cloth. Do not use solvents or harsh chemicals.

What is the operating temperature range?

The operating temperature range is -25 to 80 °C.

Where can I find the user manual?

The user manual can be downloaded for free from notice-facile.com or the IFM website.

What spare parts are available?

Spare parts include connecting cables and mounting brackets.

How do I troubleshoot if there is no output signal?

Check the power supply, wiring connections, and ensure the sensor is within its rated pressure range. See the troubleshooting section in the manual.

Can the sensor be used with IO-Link?

Yes, the PX9134 supports IO-Link for digital communication with IO-Link masters.

1 Safety instructions

Please read the product description prior to installing the unit. Please check that the product is suitable for your application without any restrictions.

If the operating instructions or the technical data are not adhered to, personal injury and/or damage to property may occur.

Please check in all applications that the product materials (see Technical data) are compatible with the media to be measured.

For gaseous media the application is limited to max. 363 PSI.

High-pressure units (5000 PSI) are supplied with a pressure relief mechanism and an integrated damping device to comply with the regulations for UL approval and to avoid any risk of injury in case of bursting when bursting pressure is exceeded.

Any manipulation of the damping device is not permissible.

When the damping device is removed, there is no damping function any more. ATTENTION: risk of injury!

For units with cULus approval this approval becomes invalid when the damping device is removed.

For units with cULus approval and the scope of validity cULus:

The device shall be supplied from an isolating transformer having a secondary Listed fuse rated as noted in the following table.

Overcurrent protection
Control-circuit wire size		Maximum protective device rating Ampere
AWG (mm)	2
26 (0.13) 1
24 (0.20) 2
22 (0.32) 3
20 (0.52) 5
18 (0.82) 7
16 (1.3) 10

The Sensor shall be connected only by using any R/C (CYJV2) cord, having suitable ratings.

2 Function and features

The pressure sensor detects the system pressure and converts it into an analog output signal.

• 0 to 10 V (PX9xxx)
  • 10 to 0 V (PX9119)
  • 4 to 20 mA (PX3xxx)
  • 20 to 4 mA (PX3229)

Avoid static and dynamic overpressure exceeding the given over-load pressure.

Even if the bursting pressure is exceeded only for a short time the unit can be destroyed (danger of injuries)!

3 Installation

Before mounting and removing the sensor, make sure that no pressure is applied to the system.

Mount the pressure sensor on a suitable process connection (see type label “Port Size”).

4 Electrical connection

The unit must be connected by a qualified electrician.

The national and international regulations for the installation of electrical equipment must be adhered to.

Voltage supply to EN50178, SELV, PELV.

▶ Disconnect power before connecting the unit as follows:
