WPTG-1 Smart Pressure Switch transfers pressure signal through high precision instrumentation amplifying, MCU data processing, and temperature compensation by built-in temperature sensor. It can be used in most of areas of pressure measuring and controlling for liquid and gas. Because of convenient and flexible adjustment, simple installation, it can be also used in most of occasions of liquid level controlling.
