Lefoo Differential Pressure Controller LFM32

Lefoo differential pressure controller is widely used for air or neutral gas detection control. Internal provides multiple working modes, more suitable for a variety of uses of air pressure control. The optional analog signal is 4~ 20mA, 0~10V, or RS485 digital signal output. The range of upper and lower pressure values for switching output type operation can be set independently. It has the function of a built-in buzzer with sound and light alarm & alarm signal output, field-programmable alarm pressure value, and custom alarm mode setting. Various pressure units can be switched to view the lowest and highest pressure values. It also provides an acousto-optic alarm and digital damping filtering degrees can be programmed on-site. The product adopts imported micro-pressure core body, digital pressure acquisition, and temperature compensation, with sensitive pressure response, long-term output stability, superior temperature performance, and other characteristics.
