The Kele DPA Series Differential Pressure Transmitter is a very cost-effective, low-range differential air pressure transmitter for duct pressure applications where measurement of pressure differentials up to 10 "W.C. is required. The DPA Series incorporates a piezoresistive, silicon, micromachined sensing element and integrated temperature compensation for excellent performance and accuracy.
