DIFFERENTIAL PRESSURE TRANSMITTER

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 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.

Differential Air Pressure Transmitter LFM11

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.

Differential Pressure Transmitter LFM33

LEFOO differential pressure transmitter LFM33 is a 3 in 1 instrument possessing a digital display gage, control relay switches, and a transmitter with current output all packed in the popular Dywer gage style housing. Combining these 3 features allows the reduction of several instruments with one product, saving inventory, installation time, and money

Lefoo differential pressure controller is widely used for air or neutral gas detection control. Internal provides multiple working modes, more suitable for a variety of uses of air pressure control. The optional analog signal is 4~ 20mA, 0~10V, or RS485 digital signal output. The range of upper and lower pressure values for switching output type operation can be set independently. It has the function of a built-in buzzer with sound and light alarm & alarm signal output, field-programmable alarm pressure value, and custom alarm mode settings.
