655A-00/01/02/03/04/05/06/07-C/P 液用差压变送器 Dwyer德威尔

655A系列 316L不锈钢液用微差压变送器用于高静压场合的微差压监测，特别适用于OEM设备，它能在过压非常高的情况下用于低至3英寸水柱的量程范围，精度达到0.25%。

655A系列变送器采用了先进的科技来保证高低压口的平衡。自动焊接制造技术使它在承受很高的压力的应用场合可靠耐用，寿命长。每个产品都带有NIST六点校准证书。

655A系列微差压变送器是全焊接的316不锈钢材质，在设计中没有采用任何O型环，特别适用于高静压应用场合，和保证不能泄露的应用场合。

SERIES 655A Differential Pressure Transmitters are designed for high static/low

DP applications designed especially for the End Users and OEM’s where extreme

overpressure and high performance of 0.25% accuracy and stability are required at

ranges down to 3 in w.c. Each unit includes a 6-point NIST certificate of calibration

which demonstrates the unit’s high level of performance.
