High Temperature Pressure Transmitter adopts imported thermost ability sensing element,make the transmitter work stability under 300℃.And it welds with cool lasing technology,there are cooling ribs between the pressure sensor chips and amplifier electrical circuit,it avoids the heat conduction efficiently. pressure sensitive core adopt shigh performance silicon piezore sistive pressure filling core.

diffusion silicon 4~20mA small differential pressure/pressure/liquid level injection can replace petrochemical,
metallurgy, electric power, food and medicine, papermaking, and textile industries. It is used to detect fluid differential
pressure, pressure, liquid level, density and other parameters, and is tested The signal is converted into 4~20mA.DC and sent to
display, calculation, adjustment or control instruments, which can form various automatic control systems.

The display pressure sensor uses diffused silicon core as sensitive element. The internal ASIC converts the sensor millivolt signal into a standard voltage, current or frequency signal, which can be directly connected to the computer interface card, control instrument, intelligent instrument or PLC. current output mode can be used for distance transmission. It is small, light weight, all stainless steel sealing structure, can work in a co-corrosion environment. The product is easy to install and has high vibration and impact resistance.

Pressure or differential pressure will cause changing of capacitance value, analog signal convert to digital signal via AD and then being transfered to microprocessor, processed by microprocessor then
convertted to 4～20mA analog electricity signal via DA
