Diaphragm pressure transmitter
Diaphragm pressure transmitter
Diaphragm pressure transmitter
Liquid, gas
solid
This product is widely used in water plants, oil refineries, sewage treatment plants, building materials, light industry, machinery and other industrial fields to realize the measurement of liquid, gas, and vapor pressure.
Pressure transmitter is a device that converts pressure into pneumatic signal or electric signal for control and remote transmission. It can convert the physical pressure parameters of gas, liquid, etc. sensed by the load cell sensor into standard electrical signals (such as 4-20mADC, etc.) to provide secondary instruments such as indicator alarms, recorders, regulators, etc. for measurement and indication And process regulation.
The pressure transmitter selects sputtering film sensor, imported silicon diffusion type, ceramic pressure sensor as sensitive components, and adopts a dedicated integrated module. After fine temperature drift, zero point, and nonlinear compensation, it can realize the control of liquid level, gas, and steam. Accurate measurement and transmission of pressure changes of other media. Realize ideal monitoring of pressure vacuum in various places in industrial and mining enterprises, scientific research institutes and other departments.
