LEFOO Pressure Sensing and Control Technology LEFOO is committed to become the leading and world-class enterprise in R&D and manufacturing, to supply professional mechanical structure controls, electronic digital sensing controls, micro pumps, which can be widely used in environmental control, mechanical equipment, intelligent equipment, home appliances, medical, power, Internet of things, data center, water treatment, water purification, and other industrial fields. LFM32 series differential pressure controller is widely used for air or neutral gas detection control. Internal provides multiple working modes, more suitable for a variety uses of air pressure control. 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 function of 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 acousto-optic alarm and digital damping filtering degree 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. Programmable Differential Pressure Transmitter Optional analog signal is 4~ 20mA, 0~10V or RS485 digital signal output. Built-in buzzer with sound and light alarm & alarm signal output Field programmable alarm pressure value and custom alarm mode setting. Buzzer Alarm System The buzzer alarm device is installed inside, and the alarm will sound immediately when the set value is reached, and the set pressure value can be adjusted manually.
