DLA20-DCA-G-4 is a type of panel meter designed to measure electrical current. It\'s a compact and accurately calibrated device suitable for most applications.

Application Field

DLA20-DCA-G-4 is suitable for applications in numerous industries, including automotive, aerospace, agriculture, construction, energy, industrial, and medical fields. It is especially applicable in large-scale electrical systems such as robotics, computer networks, telecommunications, and power plants. Whether in a control system, or as a monitoring tool, DLA20-DCA-G-4 provides the accuracy, reliability, and ease of use required for almost any application.

Working Principle

The DLA20-DCA-G-4 utilizes a shunt resistor in the electrical chain to measure current using magnetic flux technology. This type of panel meter utilizes a current coil or series of windings through which current passes and induces a magnetic field. This magnetic field is then used to measure the current and relay the results to the user.

The working principle behind the DLA20-DCA-G-4 is based on Faraday’s Law of Induction. When current passes through the coil, a magnetic field is generated around the coil which interacts with a permanent magnet in the panel meter. This magnetic field induces a voltage in the coil which is measured and used to calculate current.

The DLA20-DCA-G-4 is designed to measure both AC and DC current. AC current is measured using a current transformer which allows the current to be measured without the need to break the circuit. DC current can be measured using a current shunt resistor, integrated into the panel meters circuitry.

The current measurement accuracy of the DLA20-DCA-G-4 is ±0.1% of full scale current, and it can measure currents up to 1000 A. It has built in LED displays and a 4-20mA output signal can also be used for remote control and monitoring applications.

Conclusion

In conclusion, DLA20-DCA-G-4 is a highly accurate and reliable panel meter suitable for a variety of applications. It is easy to install and is designed to measure both AC and DC current. With its 4-20mA output signal and LED display, DLA20-DCA-G-4 provides ideal current measurement across various short-circuit and overload conditions.
