KELE OSA Thermistor and RTD Sensors KTO* Series

KELE OSA Thermistor and RTD Sensors

 

The Kele KTO* OSA Thermistor and RTD Sensors are designed to be cost-effective with accuracies of ±0.5°F (±0.28°C). 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 100Ω and 1000Ω versions. All sensors come with a three-year warranty.
