Differential Pressure Transducer LFM11

Name: Differential Pressure Transducer LFM11
Brand: LEFOO INDUSTRIAL CO.,LTD.

The LFM11 series differential pressure transducer/transmitter detects differential pressure or gauge pressure and converts this pressure value into a proportional electrical signal output for use in intelligent building energy management systems. It measures the precise and required pressure and flows for building pressurization and airflow control. It is widely using for the monitoring of air or neutral gas, and a variety of pressure units and ranges can be switched. It adopts imported micro pressure core, digital pressure acquisition, and temperature compensation, this differential pressure transmitter has the characteristics of sensitive pressure response, long-term stable output, and superior temperature performance.

Features

* LCD digital display

* 1% exactness for low-pressure measuring

* Multiple measure scale and various output signals
