LEFOO LFM11 micro differential pressure transmitter adopts high-precision MEMS sensor, digital pressure acquisition and with temperature compensation; with sensitive pressure response, long-term stable output, superior temperature performance and other characteristics. Can detect positive pressure, negative pressure or differential pressure, widely used in air or neutral gas monitoring, the internal pressure can be set up a variety of units, the range can be switched on site. It can be used for differential pressure detection in applications such as fans, blowers, filters, furnace ventilation, clean rooms, nuclear testing booths and building ventilation.
Features
* The range can be set on site with the built-in dip switch
* Response time (0.5s-4s) can be adjusted by the built-in dip switch
* The product can be fixed by mounting the back plate, and can be disassembled flexibly
* Flame-retardant ABS housing with good impact resistance and heat resistance
* Intuitive LCD digital display
