Characteristics: Easy to install and compact size. Apply to the pressure measurement of a variety of gas and liquid (include the absolute pressure measurement).  Powerful and flexible. Strong pressure sensitivity: when the total range is less than 1MPa, it can bear ten times pressure  the range.

Profile

The transmitter adopts the dry ceramic capacitance transducer  as the measure unit, in the process of measurement, the pressure react on the firm and corrosion-attack ceramic diaphragm, and then the diaphragm emerge the flexible displacement. According to the principle that the amount of capacitance is inversely proportional to the distance of the opposite poles,we can conclude out a accurate voltage signal, then the transmitter change the signal into the current signal of 4-20mA.
