The LPM10/12/16 series micro differential pressure sensor detects differential pressure or gauge pressure and converts this pressure value into a proportional electrical signal output. The LFM11 series has output modes such as 0~5VDC, 0~10VDC, or 4~20mA (separate voltage three wire system and current two wire system output, or simultaneous voltage and current three wire system output), which are used in intelligent building energy management systems to measure the precise pressure and flow required for building pressurization and air flow control.
Product Details
■ Range: 0~± 10Pa/0~± 10000Pa
Accuracy: ± 1.0% (standard type)/0.5% (high-precision type)
Output signal: 0~5VDC, 0~10VDC, 4~20mA (two-wire and three wire output, can be used simultaneously)
Multiple pressure units can be switched
■ LCD backlit digital display screen or no display screen
■ Automatic zero calibration upon startup
The response time can be adjusted on-site through the built-in dip switch of the product (20mS~2S)
■ Manual button pressure differential zero calibration
■ Adopting imported micro pressure core body
■ The rotation method is fixed to the installation back plate (the installation plate is separated from the main unit, which allows for step-by-step and staged installation)
