The MDM-21PH003L-A30 is an electronic pressure switch made by the company Danfoss. It was designed to measure and control pressure in hydraulic or pneumatic systems. Its reliable and robust construction makes the MDM-21PH003L-A30 an exceptional choice for a broad range of applications.

The MDM-21PH003L-A30 is a single stage, adjustable differential electronic pressure switch with two analog outputs. It provides good accuracy and repeatability with a wide range of adjustable set points. The external set point adjustment allows you to easily adjust the pressure switch to a specific pressure requirement. This makes the MDM-21PH003L-A30 ideal for applications such as water pressure control, air pressure control, and refrigeration systems.

The MDM-21PH003L-A30 is designed with an aluminum housing and a stainless steel diaphragm. This construction makes the pressure switch highly resistant to corrosion. It is rated for pressures up to 21 bar, with a switching accuracy of ±2 % of the full scale. It also has a range of adjustable setting thresholds and is capable of switching between 0 to 2 bar.

The MDM-21PH003L-A30 is extremely easy to install and maintain. It has an electrode-free design and can be easily connected with standard ¼” NPT (National Pipe Thread) pressure connections. The built-in LED indicator allows you to easily monitor the switch’s status.

The MDM-21PH003L-A30 is a versatile pressure switch that can be used in a broad range of applications. It is ideal for controlling pressure in heating, ventilation, and air conditioning systems. It can also be used for controlling pressure in water and waste-water systems as well as controlling pressure in industrial machinery.

The working principle of the MDM-21PH003L-A30 pressure switch is based on a diaphragm system. A pressure port is connected to the diaphragm, and as the system pressure increases the diaphragm is forced upword, which causes the switch to move into the ‘on’ position. When the pressure drops, the diaphragm forces the switch back to the ‘off’ position. The range of pressures that the switch can detect is adjustable with the external set point adjustment.

The MDM-21PH003L-A30 pressure switch is an ideal choice for a wide range of applications. Its robust construction and adjustable settings make it easy to use and maintain, while its wide pressure range and reliable performance make it an effective tool for a variety of applications. Its versatile design makes it a great choice for a broad range of industrial and commercial applications.
