Lefoo Multi-Function Differential Pressure Transmitter LFM73 The LFM73 series of multi-function digital display differential pressure transmitters/controllers use a high-precision MEMS sensor, LED digital display and transmitter output to detect the pressure difference; it can completely replace the pointer-type mechanical pressure gauge; The pressure measurement range and pressure unit of this differential pressure transmitter can be easily adjusted on site through buttons. It adopts an IP65 protection grade housing and is suitable for energy management systems, heating, ventilation and air conditioning (HVAC), VAV and fan control, environmental pollution control, static pipeline and clean room pressure measurement, smoke hood control, oven pressurization and boiler ventilation control and other fields. Features of Multi-Function Differential Pressure Transmitter LFM73 High-precision MEMS digital pressure sensor to detect positive pressure, negative pressure or pressure difference, a better alternative to the traditional 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. Built-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, support for standard Modbus RTU protocol. Cast aluminum shell, with good impact resistance, heat resistance and so on. No moving parts, shock-proof.
