Panel meters refer to electrical instruments installed in the control panels. As the name implies, the panel meters are used to measure and calculate the electrical parameters of the circuit when the system is operating. Different from the vast majority of instruments using numerical displays, panel meters are characterized by the use of pointers, such as a dial and discs to represent the values. The most commonly used panel meters are ammeters, ohmmeters, voltmeters, and watt meters.

The DLA-201R automatic panel meter is a device that specifically uses the thermoelectric principles for measuring voltage, current, and power. It is suitable for a range of low-voltage applications, ranging from 48V to 380V systems. The device offers a high accuracy of +/- 0.02 percent and features a digital display through a 4 digit alphanumeric display for the parameters. It also offers outputs to connect to a data acquisition system.

To understand how the DLA-201R panel meter works, we need to know a few important points about the use of thermoelectric principles. The DLA-201R utilizes a magnetic core to detect and measure current. An alternating current flows through the core, generating an alternating magnetic flux which in turn induces three measurement sources: one secondary coil, to measure current, and two toroidal windings, to measure voltage. These three signals are then balanced and amplified by a differential amplifier to produce an accurate output.

The output is then converted into a readable form and shown on the 4 digit alphanumeric display. Based on the parameters that are displayed, the user will be able to determine all the necessary electrical characteristics of the system. This makes the DLA-201R ideal for use in monitoring and controlling applications, as it can be used to quickly and easily set up and maintain desired system parameters.

The DLA-201R is designed to be highly reliable, with a wide operating temperature range of -20 to +50 degrees Celsius. It has been tested to EN50081-2 emissions and EN55022-1 immunity standards, a high level of protection is ensured even when the instrument is operating in harsher environments. This high degree of tolerance makes the device suitable for use in a range of industrial and commercial applications, including industrial process monitoring, automotive testing, and marine applications.

The DLA-201R is a highly versatile and reliable panel meter that offers users the ability to quickly and easily set up and maintain desired system parameters. With its high accuracy, wide temperature range, and high level of protection, the device is an ideal choice for a range of industrial and commercial applications. Furthermore, with its integrated digital display, the user can quickly and easily access the device’s settings and understand the readings.
