Low Differential Pressure Transmitter 4-20ma Modbus Output Hvac Application
Features Low Differential Pressure Transmitter 4-20ma Modbus Output Hvac Application
This transmitter can deteet differential pressure or gauge pressure then convert this pressure difference to a proportional analoguc output signal, in order to monitor and control building automation with precise pressure and flow
According to the specific conditions, set the pressure by dial-up switch
Range:0--10Pa/0--10.000Pa Accuracy:1.0%
Selectable pressure unit
LCD backlit digital display or without display Auto zero point when power on
Selectable response time field adjustable from 0.5S-4S Manual zero point push button
Adopt the imported core
Separated mounting blanket for stepped installation
