The AQD-D4U8GE24-HE is an industrial grade digital pressure switch manufactured and marketed by Dongjin Technologies. The unit employs state of the art technology to accurately monitor and switch between specified pressure. It is suitable for industrial applications such as HVAC, cooling, air compression systems, pressurization systems and more.

The AQD-D4U8GE24-HE comes in an iron or cast aluminum housing and is designed to resist temperature extremes and offer both corrosion and vibration resistance. The unit has a standard 4-20mA output and is rated for use in hazardous locations requiring UL and CSA certification. It is extremely reliable and offers a long service life even in harsh environments.

The AQD-D4U8GE24-HE is capable of measuring pressure from 0-250 PSI and is capable of both high and low pressure settings. It offers a high accuracy of +/- 0.2% and is capable of switching on/off at up to 95% accuracy. It can be further adjusted to different settings with an accuracy of 1.5% per switch point.

The AQD-D4U8GE24-HE has a wide operating range of -40°F to 230°F and is equipped with a wide variety of functions. It offers both alarm and shutdown functions. The alarm contacts can be configured for either audio or visual warnings. It also has an adjustable time delay feature that can be activated for up to 30 seconds after a switch operation.

The AQD-D4U8GE24-HE works on a simple principle. When a set pressure is reached, it will change the output signal from 4-20mA. This can then be used to either activate an alarm or shut down the system. The unit also has two programmable parameters that can be used to control the hysteresis and trip time of the system. The hysteresis determines the range of pressure around the set pressure point where the switch will still be triggered.

The AQD-D4U8GE24-HE is suitable for a variety of industrial applications. It is especially well suited for HVAC and cooling systems, air compression systems, and pressurization systems. Its heavy-duty construction and long service life make it an excellent choice for any industrial application requiring accurate pressure monitoring and switching.
