LFM11 series differential pressure transmitter adopts high-precision MEMS sensor, digital pressure acquisition and temperature compensation method; it has the characteristics of sensitive pressure response, long-term stable output, and excellent temperature performance. It can detect positve pressure, negative pressure or differential pressure. It is widely used in the monitoring of air or neutral gas. Various pressure units can be set inside, and range switching can be performed on site. It can be used for differential pressure detection in applications such as fans, blowers, filters, furnace ventilation, purfhication workshops,nuclideinspecion booths and building ventilation.
Pressure range can be set on site through the built-in DIP switch.
The responsetime (0.5s-4s) can be adjusted through the builtin DIP switch.
The product is fixed byinstalling backboard, which can be flexibly disassembled.
Adopt flame-retardant ABS shell, with good impact resistance, heat resistance and other properties.
Intuitive LCD digital display.
