The new dry hermetically sealed transducer-transmitter (DHT) is ideally suited for commercial HVAC equipment where accuracy, vibration tolerance, and the ability to operate in harsh environments is vital, states the manufacturer. It offers pressure ranges from 50 to 750 psi and is designed to operate in temperatures from -40 degrees to 275 degrees F (-40 degrees to 135 degrees C). The unit features a stainless steel casing that is environmentally sealed to protect the nondrift, ceramic capacitive sensing element from contaminants.
