CET20A, also known as contact electric transducer, is a device used for measuring and monitoring the contact pressure. It’s usually installed in electrical appliances like circuit breakers, switches and regulators. The transducer sends contact pressure signals to a meter or display for real-time monitoring or recording. It’s widely used in low voltage applications to protect the electric equipments from overload conditions, short circuit or other faults.

CET20A contact electric transducer works on the principle of capacitive sensing. It consists of two metallic plates (electrodes) and a dielectric material in between. When the contact pressure is applied, it causes electrical charge to move from one electrode to the other. The amount of current that flows between the two plates depends on the capacitance of the material, which is a measure of the electrical charge it can store. This current gives an indication of the contact pressure. The transducer then converts this information into a voltage signal, which is sent to a meter or display for monitoring or recording.

CET20A has a wide range of applications. It’s used to measure and monitor contact pressure in various electrical appliances such as circuit breakers, switches, regulators, motors and transformers. It can also be used to check the contact pressure of electric contacts in ground fault protection systems. Additionally, it can be used to measure and monitor the pressure in fuel injection systems. This helps in controlling the fuel consumption of an engine and ensuring optimal efficiency.

CET20A contact electric transducer has several advantages over other pressure sensing devices. It’s accurate, reliable and easy to install. It’s also highly resistant to temperature and mechanical shock, making it suitable for use in harsh environments. Furthermore, it has a wide range of applications including but not limited to, electrical machinery, fuel injection systems and ground fault protection systems.

In conclusion, CET20A contact electric transducer is an indispensable device in many industrial and home applications. It measures and monitors contact pressure in various electrical appliances, helping to protect them from overload conditions or short circuits. It has an accurate, reliable and robust design, making it suitable for use in harsh environments. Additionally, it has a wide range of applications, including but not limited to, electrical machinery, circuit breakers, fuel injection systems and ground fault protection systems.
