Product Description:
The digital differential pressure transmitter adopts the original imported differential pressure sensor as the pressure sensing element,which has the characteristics of high accuracy and good long -term stability.
Users can choose 4~20mA current output or RS485 Modbus RTU output according to their needs.
The product adopts wall -mounted installation,which is suitable for ventilation system,fire prevention and smoke exhaust system,fan detection,air conditioning filter system and other fields that require slight differential pressure detection.
Technical Characteristics:
4 digits LED displays pressure in real time.
4~20mA / RS485 output
Unit switch,reset function etc
Support address,baud rate,filter constant,display digit setting
Product anti-electromagnetic interference design,stable and reliable date
Application:
Smoke prevention system
