Unit Tube Pressure

SKU:U130

Description

Tube pressure is a wide range air pressure sensor that supports -100 ~ 200Kpa. You can connect one end of the tube to the gas inlet. This sensor transmitted onto mapping value -100 ~ 200Kpa and 0.1 ~ 3.1V voltage output. Also having a protective housing for long term stability. It’s an accessory that your industrial use cannot live without.

Output voltage and pressure value conversion

//P: Actual test pressure value, unit (Kpa)
//Vout: sensor voltage output value
P = (Vout-0.1)/3.0*300.0-100.0
