9013-3-0101 is a three way normally closed differential pressure control switch, commonly used for system pressure monitoring or differential pressure control. The switch is very reliable and is widely used in HVAC applications, industrial gas and liquid systems, medical and industrial process control.

The 9013-3-0101 switch can be used in systems to monitor the pressure of a single point, for example a water or air mains. It can also be used in two point systems, such as HVAC systems, or in a differential pressure control application. In a differential pressure control, two pressure points are monitored and compared. The differential pressure is the difference between the two sensors. When the differential reaches a preset level, the switch activates. The advantage of this type of system is that the pressure switch can be set to trip at pre-determined differential pressures, for instance a 10 PSI differential pressure would trip the switch.

Differential pressure control switches, such as the 9013-3-0101, are widely used in the HVAC industry in order to control the operation of air conditioning fan outdoor units, compressors or heating elements, as well as in water systems to control zone valves. The switch operates on the principle of differential pressure on the two sides of a diaphragm, an enclosed bellows or a sealed piston. As internal pressure rises, the pressure difference across the diaphragm or other sensing element reaches a predetermined set point and the switch actuator will operate, triggering an electrical contact.

The main advantage of the 9013-3-0101 switch is its reliability and ease of installation. The switch requires minimal calibration and is designed to fit into most standard switch connections. With no mechanical parts, such as cams or levers, to wear out, the switch is also incredibly reliable and long lasting; this means that it will continue to operate at its reliable pressure set point for years. The switch also has two adjustable snap switches, enabling the user to select a wide range of set points. Finally, the switch has a field adjustable dial allowing the user to accurately set the required pressure set point.

In conclusion, the 9013-3-0101 switch is an incredibly reliable and versatile pressure control switch, suitable for various HVAC applications. It is easy to install and can be set up to operate at a wide range of pressures. With no moving mechanical parts, it is highly reliable and long lasting, ensuring that it continues to provide accurate pressure control for years.
