Relative pressure transmitter LFM33

differentialdigitalanalog

Lefoo Differential Pressure Transmitter LEFOO LFM33 micro differential pressure transmitter/controller adopts high-precision MEMS digital pressure sensor, which can detect positive pressure, negative pressure or differential pressure products with optional analog signal 4~20mA & 0~10V or RS485 signal output; optional relay switch control, supporting a variety of working mode settings to match the actual application requirements; can independently set the relay switch action pressure point; through the internal The pressure unit can be switched and the digital damping filter can be edited on the spot, which is widely used in air or neutral gas detection and control. Suitable for all kinds of ventilation, air conditioning systems and equipment gas pressure detection, clean rooms, laboratories, gas pipeline filter resistance of differential pressure detection applications. Features * High precision MEMS digital pressure sensor to detect positive, negative or differential pressure * Multifunctional product combining LCD digital display, switch control and transmitter output * Adjustable internal range output range, multiple pressure units can be switched * Built-in buzzer, provide sound and light glance, can set the alarm pressure value range on site * RS-485 serial communication, support standard Modbus RTU protocol * Flame-retardant ABS shell, with good impact resistance, heat resistance and other properties
