Air/Water/Oil Pressure Sensor Output 4-20mA/0-5V/RS485
This pressure sensor can be used for air/water/oil pressure measurement. 
It uses the piezoresistive principle and the core components are made of high-performance silicon pressure cores. The measuring range -0.1~100MPa/ -1~1000bar/ -14~14503psi, medium temperature -40~+60℃ (-40~+140℉). The housing of the pressure sensor is a 304/316L stainless steel sealing structure, which has small size and light weight. It has good anti-vibration and anti-shock performance. The pressure sensor output signal are available with standard current (4-20mA / 0-20mA), voltage (0-5V / 1-5V / 0-10V) and RS485 signal.
Stability is an important performance specification for a pressure sensor. It refers to the ability of a pressure sensor to remain unchanged after a period of use. If the pressure sensor need to operating for a long time and it is difficult to replace or recalibrate it under certain environment, it requires high stability for the pressure sensor. The main factor affecting the long-term stability of pressure sensors is their application environment. Therefore, before selecting a pressure sensor, it is necessary to have a good grasp of the environment in which it is used, and select a right product according to the specific environmental characteristics.
