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.
