Differential Pressure Transmitter LFM33

Name: Differential Pressure Transmitter LFM33
Brand: LEFOO INDUSTRIAL CO.,LTD.
Price: 8-360 USD
Rating: 4.8 (50 reviews)

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.
