Dwyer pressure transmitter series 672 Low Pressure Transducer

The Series 672 Low Pressure Transducer is a perfect solution to any application where a very accurate low pressure transducer is necessary. Using
variable capacitance technology, the Series 672 is designed to measure pres-sures as low as 10 w.c. up to 400 w.c., very low ranges for a single connection
pressure transducer. The 672 also features a 0.25% F.S. accuracy. Use the Series 672 in liquid level, flood warning, waste water, clean room, and open
channel flow applications.
