Pressure Sensor Transmitter Working principle

 

Process pressure via the pressure sensor to change pressure signal to electrical signal, through the difference normalized amplifier, the output amplifier amplification, then via current voltage (V/I) converter, transformed as 4-20mA or 0-10 mADC standard current signal.

Pressure Sensor Transmitter Application

 

Widely used in petroleum, chemical industry, metallurgy, electric power, light industry, building materials, medicine, environmental protection, scientific research, and other enterprises and institutions, realize to test the process fluid pressure, and is suitable for various occasions all-weather environment and all kinds of corrosive liquid.

 

Pressure Sensor Transmitter Characteristics

 

• High accuracy, high stability. Except import original sensor has been used laser correction, for temperature drifting, it is also subtly compensated, therefore in the working temperature range, the nonlinear for transmitter is small, and temperature is stable.
• Good cost performance.
• Reliable mechanical protection, explosion protection, suitable for all kinds of severe environments.
• 4 ~20mA standard current signal output, two wire, or 0 ~ 10 mADC standard current signal output, three wire system.
• Can be used for measuring viscous, crystallization and corrosive medium.
• Small volume, light weight, installation/ adjustment, easy to use.
