Hydrostatic testing module is a high reliability of ceramic capacitance pressure sensor, has the excellent properties of corrosion resistance, high impact elasticity, and water, oil, gas and so on most direct contact with the medium, able to handle the water hammer effect, perfect ceramic high thermal stability at the same time Can make it work temperature range - 40 ℃ ~ 150 ℃, ceramic capacitance pressure sensor work no liquid in the process of transmission, direct effect on the ceramic membrane process pressure, base between the electrode and membrane electrode capacitance change is proportional to the pressure value.When overloading, the diaphragm will not be damaged, and when the pressure returns to normal, the performance will not change.It thoroughly solves the problem of poor overload capacity at low range, and is the updated product of diffused silicon pressure sensor.At the same time, the power consumption is smaller, specially designed for the Internet of things, which can work continuously for 10 years without replacing the battery.
