Low Differential Pressure Transducer LFM108

 Low Differential Pressure Transducer LFM108

This product is suitable for heating, ventilation and air conditioning (HVAC), energy management systems, VAV and fan control, environmental pollution control, static pipelines and clean room pressure, smoke hood control, oven pressurization and furnace ventilation control, etc. The LFM108 low pressure sensor detects differential pressure or gauge pressure and converts this differential pressure into a  proportional electrical signal output. LFM108 has an analog output of 0～5/10Vdc or 4～20mA for building energy management systems. This transducer can measure the precise pressure and flow required for building pressurization and airflow control.LFM108 adopts an imported pressure core, which has the characteristics of sensitive pressure response, stable long-term output, and superior temperature performance.

 

Features

* 1% exactness at low pressure measurements

* Optimal for HVAC application
