672-1/2/3/4/5/6/7/8/9-A 低压力变送器 Dwyer德威尔-上海茂培供应672系列 低压力变送器采用了可变电容技术，广泛用于低压力应用场合。它能测量低至10英寸水柱，高至400英寸水柱。对于单压来说，这是非常低的测量范围。精度为0.25%，它可用于监测液位，水位，洁净室，明渠流量等应用场合。

The SERIES 672 Low Pressure Transducer is a perfect solution to any 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 pressures as low as 10 in w.c. up to 400 in w.c.,

very low ranges for a single connection pressure transducer. The 672 also features

a 0.25% FS accuracy. Use the Series 672 in liquid level, flood warning, waste water,

clean room, and open channel flow applications.
