Hansen introduces pressure/temperature transducer for industrial refrigeration

Hansen Technologies Corporation introduces the first integrated pressure/temperature transducer model HPT717 for industrial refrigeration service. This robust transducer can be used in a variety of applications including superheat sensing, subcooled liquid sensing, and non-condensable gas sensing. The HPT transducer measures both temperature and pressure at the same point in the system, calculates superheat or sub-cooling, and outputs a 4-20 mA signal. The HPT transducer measures superheat or sub-cooling of refrigerant over a temperature range of -35ºF to +150ºF (-37ºC to +65ºC) with higher accuracy than other commonly available methods.
