Current Transducers

CR5210S-30 is a type of current transducer. It is composed of a sensing element and a closed loop electronic conditioner. Its main function is to convert the current signal of the measured circuit into a standard signal, and transmit it to the control device. The CR5210S-30 is commonly used in corrosive or harsh environmental conditions. It is a combination of a temperature compensated shunt resistance in a stainless steel housing and a signal conditioning circuit.

Application Field

The CR5210S-30 current transducer can be applied in a variety of industrial installations to measure DC electric currents. It can be used for recharging and starting of machines, providing current measurements in systems such as cranes, elevators, escalators and industrial engines. It has excellent precision and accuracy of output signals. It is also used in power electronic equipment and instruments.

Working Principle

The working principle of the CR5210S-30 current transducer is based on its sensing element. It uses a temperature compensated shunt resistance to convert the electrical current into an appropriate voltage signal in a proportional way. The shunt resistance is connected in the system in such way that the measured current, through the shunt resistance, is converted into an output voltage signal which is representative of the current flowing in the circuit. The output voltage signal is then fed to the closed loop electronic conditioner. This is a signal conditioning circuit that provides the necessary protection, gain and offset adjustment, power range selection and temperature compensation.

The electronic conditioner helps to stabilize the output signal of the current transducer from possible damage due to interferences and noise from the environment. It also provides high accuracy and repeatability of the output signal. The collected signal from the conditioner is then fed to the control device for signal processing. The control device may be an AI system or a numerical display instrument. The display instrument displays the measured current.

Conclusion

In summary, the CR5210S-30 current transducer is a combination of a temperature compensated shunt resistance in a stainless steel housing and a signal conditioning circuit. It is commonly used for recharging and starting of machines, providing current measurements in systems such as cranes, elevators, escalators and industrial engines. It is accurate and repeatable and can be used in corrosive or harsh environmental conditions. Working based on the sensing element, it can convert a physical current into an appropriate voltage signal, which is then sent to the control device for further processing and display the measured current.
