The ProSense DPTA series differential air pressure transmitters are precision-engineered for accurate low differential pressure management of air and non-condensing, non-corrosive gases. Units are equipped with an ultra-thin single silicon crystal diaphragm capacitive sensor to provide inherent repeatability and stability. These systems are designed with brass barbed pressure ports, removable terminal blocks and a rugged ABS housing for DIN rail or panel mounting. The series is available in ranges from 0.1 in. to 25 in. water column to measure positive, negative and bi-directional pressures, with the ability to withstand 15 psi overpressure without damage or calibration shift.
