2088Industrial pressure transmitter 4-20mA/HART/RS485M20*1.5

 KY3002 series products provide high performance intelligent configuration pressure measurement solutions.KYUE  advantages of silicon technology, capacitance and analog circuits enable excellent performance in sensor stability, low power consumption and high frequency response.Modular design and unique production technology can provide users with flexible choice of products, can meet the application needs of users in various industries 

The series transmitter consists of two parts: the pressure sensor and the pressure signal converter. 

Includes two parts ：pressure transmitter and pressure signal-transform device.

Pressure sensor utilizes the piezoisor effect of silicon and good mechanical properties, applying diffusion and ion injection techniques to photoengrave piezoo-resistor elements on the silicon membrane.When the measured pressure is applied on the sensitive element of the core, the sensor output has a corresponding voltage signal output, whose size is proportional to the added pressure.The pressure signal converter, providing a constant current source to the pressure sensor and amplifying the weak voltage signal output by the pressure sensor, then V/I and 4~20mA constant current signal.
