Choosing Temperature Sensors for HVAC and Chiller Equipment – A Variety of Sensors Designs Offer Options and Trade-offs in Performance and Reliability.

Highlighting that efficient operation of industrial HVAC and chiller equipment depends upon optimum temperatures of refrigerant and lubricating oil, this paper states that negative temperature coefficient (NTC) thermistors of various resistance values are the most common sensors used for efficient operation. It presents durability, and quick response to temperature change as the advantages of thermistor,…
