Frequently Asked Questions - PU1700 IFM
How do I wire the IFM PU1700 pressure sensor?
The sensor uses a 2-wire 4-20 mA connection. Connect the brown wire to positive supply (10-30 V DC) and the blue wire to the signal return. The output is a current loop proportional to pressure. Verify the load impedance stays within the specified range.
What output signal does the PU1700 provide?
The standard output is a 4-20 mA analog signal, where 4 mA corresponds to 0 bar and 20 mA to 100 bar. For additional options, check the model number suffix.
What is the maximum pressure range for the PU1700?
The standard measuring range is 0 to 100 bar relative. The sensor can withstand an overpressure of 150 bar without damage.
Can I use the PU1700 for hydraulic applications?
Yes, the stainless steel housing and G1/4 connection are suitable for hydraulic oils and compatible fluids. Ensure the fluid is compatible with the wetted materials (stainless steel and Viton seal).
How do I zero the sensor?
The PU1700 is factory calibrated and requires no manual zero adjustment. For precise offset errors, use the teach-in function of the connected controller or a multimeter to verify a 4 mA output at ambient pressure.
What is the ambient temperature limit?
The sensor operates in ambient temperatures from -10°C to +70°C (storage -25°C to +80°C). The process temperature can range from -25°C to +80°C without affecting performance.
What is the protection class of the PU1700?
The device is rated IP67 (IEC 60529), meaning it is dust-tight and protected against temporary immersion in water. The cable entry must be properly sealed.
How should I clean the sensor?
Use a soft, dry cloth to wipe the exterior. For stubborn dirt, use a mild detergent with water. Do not use aggressive solvents or high-pressure cleaners as they may damage the enclosure.
Does the PU1700 require regular maintenance?
It is maintenance-free under normal conditions. Periodically check the process connection tightness and inspect the cable for damage. Calibration should be verified annually for high-accuracy applications.
Can I repair the sensor if it fails?
The sensor is non-repairable and contains no user-serviceable components. If it malfunctions, replace the entire unit. Contact IFM support for a replacement model.
