Passive Temperature Probes

Passive Temperature Probes

Shop all Passive Temperature Probes at iACS. Unlike active transmitters, a passive temperature sensor operates by changing electrical resistance in response to thermal fluctuations—typically using NTC (Negative Temperature Coefficient) or PTC thermistors—without requiring a separate power supply. For a deeper understanding of how these components fit into broader building management architectures, read our guide on the application of sensors in the HVAC and air handling systems.

If you need assistance matching a probe to your controller, please Contact Us. Browse the full range at iACS.
