KTD Thermistor & RTD Sensor
Brand: Kele
The Kele KTD Duct Thermistor and RTD Sensors are designed to be cost effective with accuracies of ±0.28° C (±0.5° F).
Each uses metal enclosures and is constructed for easy installation with any building automation system (BAS).
The thermistor is made of a very stable, pre-aged material that offers long-life reliability for HVac control.
The platinum RTD comes in 100 Ohms and 1000 Ohms versions.
Features- Economical
- Metal enclosures with stainless steel probes
- Thermistor or RTD sensor selections
