- product introduction:Lfm208 residual pressure sensor - with imported differential pressure sensor, high-quality amplification circuit, strict production process, perfect inspection and aging test equipment, we have created a precision residual pressure sensor.
The precision residual pressure sensor is widely used in the residual pressure monitoring and control system of building elevator front room and aisle, elevator combined front room, fire stairs, etc.; it is also used in the differential pressure measurement and control system of indoor and outdoor pressure difference detection and control, filter blockage monitoring system, etc.
The simple and economical appearance design is satisfied with the complex installation site environment and engineering cost control, while retaining the accurate measurement of other differential pressure changes. The output mode of the product adopts RS-485 digital output of standard Modbus RTU protocol, two bus communication and computer programming. In the installation, only one bus is needed to connect each sensor to the RS-485 communication bus network or two buses to realize signal acquisition of multiple sensors. Compared with the traditional analog sensors, the trouble of wiring is greatly reduced.
