Frequently Asked Questions - PX3237 IFM
How should I mount the PX3237 pressure sensor?
Mount the sensor with the process connection (G1/4) tightened to the required torque. Ensure the sealing surface is clean and use a suitable gasket. The sensor can be installed in any position, but avoid direct vibration.
What is the maximum pressure this sensor can measure?
The PX3237 has a measuring range of -1 to 10 bar relative pressure. Do not exceed the maximum burst pressure of 30 bar to avoid damage.
How do I set the switching output?
Use the two integral buttons and the display to access the parameters. Navigate to SP1 (switch point 1) and rP1 (reset point) to define the hysteresis. Confirm with the ENT button.
Can I use this sensor with 12V supply?
The PX3237 requires a supply voltage of 18 to 32 V DC. Operating below 18V may cause incorrect readings. Use a regulated power supply that delivers at least 18V.
How do I connect the sensor to a PLC?
Connect the brown wire to positive supply (+24V), the blue wire to 0V, and the black wire carries the 4-20 mA analog signal. For the switching output, use the white wire if present; otherwise consult the manual.
What is the accuracy of the PX3237?
The sensor has an accuracy of ±0.5% of full scale, meaning ±0.05 bar over a 10 bar range. This ensures reliable pressure monitoring.
How often should I clean the sensor?
Clean the sensor when it is dirty or before calibration. Use a soft, dry cloth. If needed, dampen with water or a mild detergent. Avoid abrasive cleaners or solvents that could damage the membrane.
Is the sensor suitable for outdoor use?
With an IP67 protection rating and a stainless steel housing, the PX3237 is resistant to dust and temporary immersion. It is suitable for industrial environments, but do not expose the cable to continuous bending.
Can I adjust the zero point?
Yes, the sensor has a zero point calibration function. Press and hold the button for several seconds to reset the zero point in pressureless condition. This helps compensate for mechanical drift.
What should I do if there is no output signal?
First check the supply voltage (18-32V DC) and the wiring connections. Ensure the process pressure is within the measuring range. If the display shows 'Err', perform a power cycle. If the problem persists, contact IFM technical support.
