Characteristics: Pratical, multi-functional, and economical. Easy to install and compact size. The operation is flexible. With LED displaying gauge outfit and controlled contact for selection. Strong pressure sensitivity: when the total range is less than 1MPa, it can bear ten times pressure the range.

Profile: The PTS10 series economical pressure transmitter adopts the diffusion silicon or ceramic piezoresistive diaphragm as the measure unit. This series include two models: PTS11 and PTS12. The PTS11 is ordinary model. It can be used for measuring the pressure of a vairety of gas and liquid(include the absolute pressure measurement).  The PTS12 is smart and economical model. 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.
