DK-3716-E222-CS is a type of sensor used in air-conditioning and refrigeration systems. It is designed to detect the pressure in the condenser and evaporator of an air-conditioning or refrigeration system and compare the pressure against a reference level. The DK-3716-E222-CS is capable of sensing pressure over a range of up to 40 bar (400 kPa). It is suitable for any type of air-conditioning or refrigeration system.

The DK-3716-E222-CS is comprised of a housing containing a metal diaphragm on the end housed by a metal mounting plate and attached to the system by a compression fitting. Pressure is sensed through the diaphragm. The other end of the pressure sensor has two electrical terminals. A signal is generated when the reference pressure set on the outside of the diaphragm is exceeded. This signal can be used to activate an alarm, open or close valves, or turn on a motor or other device associated with the system.

The working principle of the DK-3716-E222-CS is based on Wheatstone Bridge technology. Such a bridge uses two tension-sensitive resistors connected to the two surfaces of the diaphragm to sense any variation in the potential difference between the two points. When the pressure within the system exceeds the reference value, this difference will cause a change in the resistance of the Wheatstone Bridge, which will in turn produce a signal.

The DK-3716-E222-CS is widely used in industrial, commercial, and residential refrigeration and air-conditioning systems. It is particularly useful as a safety measure to prevent the condensation or evaporation pressure from reaching dangerously high levels. This device can be connected to a computer or other system control device, allowing for remote monitoring and control of the pressure within the system.

The DK-3716-E222-CS is a reliable, accurate, and cost-effective solution for a wide range of air-conditioning and refrigeration applications. It is highly resistant to environmental conditions such as humidity and temperature, making it suitable for use in even the most extreme conditions. Additionally, it is easy to install, making it a versatile and practical solution.
