差压变送器 636D-0/1/2/3/4/5/6/7/8-LP Dwyer德威尔

636D系列 防爆差压变送器能用于监测液体，气体和蒸汽的差压。精度为0.5%，4-20mA的标准输出信号，可选1-5VDC输出。NEMA 4 防护***别的外壳，全316不锈钢的材质能够用于恶劣的场合，可兼容绝大多数介质。它为CSA认证的防爆***别能用于危险场合，还达到美***腐蚀工程师协会的标准能用于海上设施。

SERIES 636D Differential Pressure Transmitter can be used for measuring pressures

of liquids, gases & vapors. All available ranges have an excellent 0.5% FS accuracy

with a 4-20 mA Output standard or optional 1-5 VDC output. The NEMA 4 housing is an

all 316 welded construction that is designed to withstand the harshest environmental

conditions. With all 316L wetted materials, this transmitter is compatible with most

media. These units are CSA approved explosion-proof for use in the specified

hazardous locations and meet NACE standards for off-shore applications.
