Frequently Asked Questions

What is the IFM LDH290 humidity sensor used for?

The IFM LDH290 humidity sensor is used for monitoring and controlling relative humidity and temperature in industrial environments. It is commonly applied in HVAC systems, clean rooms, and process control panels where accurate, analog signal output is required for integration with PLCs or building management systems.

What are the specifications of the IFM LDH290 humidity sensor?

The IFM LDH290 is a DIN rail-mountable, open-mounted humidity sensor with a plastic housing and analog display. It measures relative humidity from 0 to 100% with an accuracy of 4, and outputs a 4 to 20mA temperature signal with ±1K accuracy. Operating temperature range is -40°C to 60°C.

Where to buy the IFM LDH290 humidity sensor worldwide?

You can source the IFM LDH290 humidity sensor through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine IFM components for industrial applications.

How to install the IFM LDH290 humidity sensor on a DIN rail?

To install the IFM LDH290, snap the sensor onto a standard DIN rail in a panel or enclosure. Ensure the open-mounted housing allows proper airflow for accurate humidity measurement. Wire the 4 to 20mA output to your controller per the IFM manual. Avoid mounting near heat sources or condensation-prone areas.
