M12 – Differential Pressure Type Velocity Transmitter
|
Description
Description:
M12 series velocity transmitter is used for measuring low pressure of air and non-combustible gases in order to monitor and control building automation, HVAC, and cleanroom systems. These transmitters boast of their outstanding performance, high quality, and economical pricing. This transmitter can detect differential pressure or gauge pressure then convert this pressure difference to a proportional analog output signal, in order to monitor and control building automation with precise pressure and flow.
Technical Detail:
- Selectable measuring unit
- LCD backlit digital display or without display
- Auto zero point when power on optional
- Selectable response time field adjustable from 0.5s to 4s
- Manual zero-point push button
- Easy installation
