Unit Tube Pressure

SKU:U130

Description

Unit Tube Pressure is a positive and negative pressure gauge that supports a wide measurement range of -100 ~ 200Kpa. When in use, it is connected via a tube, with the other end connected to the gas measurement environment. The sensor maps the range -100 ~ 200Kpa to output a voltage of 0.1 ~ 3.1V. It comes with a fully enclosed protective shell, effectively ensuring the stability of the sensor, making it very suitable for applications such as gas pressure detection in industrial equipment.

Features

• Internally integrated and compensated pressure sensor
