The LFM 53 series differential pressure transmitter adopts the thermal micro-pressure core, use the micro-flow path integrated by the sensor chip, detecting air pressure by detecting the changes in thermal flow. LFM53 has the characteristics of strong overload capacity, strong anti-interference ability, wide measurement range, and multi-signal output. It is widely used in the detection of air or neutral gas, such as HVAC, process control, environmental control, clean room, clean room or other systems that require micro-differential pressure detection.
Adopt imported thermal micro-pressure core, sensitive pressure reactions.
Overload pressure up to 2 bar.
Accuracy up to 0.5%F.S, strong stability and good repeatability.
Easy to install, not sensitive to the installation location.
Strong anti-interference ability, optional isolation output.
Min Measurement range ±25Pa.
