K3TF-A915 is a type of panel meters. It is used to measure current, voltage, etc., once applied with a DC power supply(0 ~ 20 mA). The following introduces its application field and working principle.

Applications of K3TF-A915

Generally, K3TF-A915 panel meters are used in automation systems, energy management systems and instrumentation systems. For automation systems, they are used to measure and control various physical parameters such as current, voltage, power, temperature and pressure, and then the real-time control is carried out based on these measured values. For energy management systems, they can be used to monitor and optimize energy consumption. For instrumentation systems, K33TF-A915 panel meters can provide reliable reading accuracy for measurement of voltage, current and other physical parameters.

Working Principle of K3TF-A915

K3TF-A915 panel meters are composed of a DC power supply, a current-sensing resistor and a sensing circuit. The DC power supply supplies power to the resistor, and then the sensing circuit converts it to a usable direct current (DC). The sensing circuit is composed of various circuit elements like a spring, which can detect the current passing through the resistor. After being converted by the sensing circuit, the DC current is transformed to a voltage signal, which is then displayed on the meter.

When the K3TF-A915 panel meter is powered, the current-sensing resistor conducts current of 0 ~ 20 mA, then it passes through the sensing circuit, and the voltage generated by it is sensed and snapped in the sensing circuit, and the voltage signal is amplified to its final display value. So, this is the working principle of K3TF-A915 panel meters.

In conclusion, K3TF-A915 panel meters are suitable for measuring and controlling physical parameters in automation systems, energy management systems and instrumentation systems, and their working principle is mainly composed of a DC voltage source, a current-sensing resistor and a sensing circuit.
