LFM32 Differential Pressure Transmitter/Controller adopts high-precision MEMS digital pressure sensor, which can detect positive pressure, negative pressure or differential pressure.
It has 4~20 mA & 0~10V or RS485 signal output, and variety of working mode settings to match the actual application requirements. Relay switch control is optional and can set pressure point independently. The internal buzzer and LED will indicate pressure alarm. Pressure unit switching and digital damping filter degree can be edited on site. It is widely used in air or neutral gas detection and control. It is suitable for air pressure detection of various ventilation and air conditioning systems and equipment, and for differential pressure detection of filter resistance in clean-room, laboratories, and gas pipelines.
Adopt high accuracy of MEMS digital pressure sensor, detectpositive pressure, negative pressure and differential pressure.
Combine LCD digital display, switch control and transmitter output.
Internal output range scope can be adjusted.various switchable pressure units.
Built-in buzzer with sound-light alarm, alarm pressure range can be set on site.
RS-485 serial communication, support standard ModBus RTU protocol.
Housing is made of FR-ABS, satisfactory impact resistance and heat resistance, etc.
Support setting replay working mode. Optional control or alarm output mode, with LED signal.
