Air Differential Pressure Transmitter LFM52

LEFOO LFM52 differential pressure transmitter is an ideal product for industrial pressure measurement, which has both the flexibility of multi-range sensors and the high performance of single-range sensors. It has built-in a variety of optional pressure ranges and unit selections, and can be easily adjusted on site through the built-in dial switch. It adopts an IP65 protection grade shell and is equipped with stainless steel conduit connectors for easy wiring. It is suitable for HVAC, energy management System, VAV and fan control, environmental pollution control, static pipeline and clean room pressure, smoke hood control, oven pressurization and ventilation control and other fields.


Features


* High-precision MEMS micro-pressure core body, wide temperature compensation, and sensitive pressure response

* 5-digit LCD digital display, clear display

* Field-available zero button, selectable pressure ranges

* Strong stability and long service life

* IP65 protection grade shell
