655A-00/01/02/03/04/05/06/07-C/P 液用差壓變送器 Dwyer德威爾

655A系列 316L不銹鋼液用微差壓變送器用于高靜壓場合的微差壓監(jiān)測，特別適用于OEM設(shè)備，它能在過壓非常高的情況下用于低至3英寸水柱的量程范圍，精度達(dá)到0.25%。

655A系列變送器采用了先進(jìn)的科技來保證高低壓口的平衡。自動焊接制造技術(shù)使它在承受很高的壓力的應(yīng)用場合可靠耐用，壽命長。每個產(chǎn)品都帶有NIST六點(diǎn)校準(zhǔn)證書。

655A系列微差壓變送器是全焊接的316不銹鋼材質(zhì)，在設(shè)計中沒有采用任何O型環(huán)，特別適用于高靜壓應(yīng)用場合，和保證不能泄露的應(yīng)用場合。

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.
