Pressure gauge
YTT-150 differential remote transmission pressure gauge

Purpose
是二线制本质安全型隔爆仪表,用于测量对铜及其合金不起腐蚀作用的液体、气体和蒸汽的压力。 YTT-150 differential remote transmission pressure gauge is a two-wire intrinsically safe explosion-proof instrument for measuring the pressure of liquids, gases and vapors that do not corrode copper and its alloys. After the instrument is equipped with a damper, it can measure the pressure of pulsation, shock and sudden unloading medium. With the diaphragm in place, it can measure pressures with high viscosity and corrosive properties. In addition to the pressure indication on the spot, this instrument also continuously outputs a 0-10mA or 4-20mA DC signal that is linear to the measured pressure signal. It can be combined with the DDZ-II or DDZ-III transmission unit display, Record and adjust the instrument for networking and form an automatic recording, adjustment and control system. Suitable for petrochemical, metallurgy, power station, light industry and other departments.
