The P399 Series electronic pressure transducer is a compact, direct-mount transducer designed for higher accuracy and for use with a variety of controls in commercial refrigeration and air conditioning applications, says the company. Its stainless steel construc-tion provides durability, prevents potential refrig-erant loss, and resists electro-magnetic interference and damage due to shock, vibration, and pressure pulsations, the company says. Environmentally sealed electronics withstand the effects of temperature swings, high humidity, condensation, and icing.
