LFM73 series digital diferential pressure transmitter adopts high-precior, LED digital sion MEMS sensdisplay and transmitter output combination, used to detect the size of the pressure difference; Can completely replace the pointer type mechanical pressure gauge; The differential pressure transmitter pressure measurement range pressure unit can be easily adjusted by pressing the button, with IP65 protection grade housing, suitable for energy management systems, HVAC, VAV and fan control, environmental pollution control, static pipeline and clean room pressure, smoke hood control, oven pressurization and boiler risk control system and other fields.
High-precision MEMS digital pressure sensor to detect positive pressure, negative pressure or pressure difference, a better alternative to the traditiona pointer mechanical watch.
Versatile product that combines high-lighted LED digital display, switch control and transmitter output.
The output range of the internal range is adjustable, and a variety of pressure units can be switched.
Buit-in buzzer, provide sound and light alarm, can set the alarm pressure value range on site.
Optional relay output or alarm, and at the same time LED indication.
RS-485 serial communication, supportfor standard Modbus RTU protocol.
Cast aluminum shell, with good impact resistance, heatresistance and so on.
No moving parts, shock-proof.
