Panel meters are devices displaying a physical quantity in the form of an analog signal. This makes them ideal for applications such as process monitoring and control, safety monitoring, and general process measurement. The DLA20-ACA5-1-AC1-B is a type of panel meter featuring an analog output signal. This article will explore the application field and working principle of the DLA20-ACA5-1-AC1-B.

The DLA20-ACA5-1-AC1-B is a 4-20 mA current output panel meter designed for process control applications in hazardous environmental areas. It is suitable for a wide variety of industrial physical inputs such as pressure, vacuum, temperature, and level. As with many panel meters, it features a 0-10V voltage signal output, and is available with a selection of power supply options, depending upon the requirements of the user. The output signal is adjustable from -10 % to +10%; this makes it ideal for applications with varying degrees of accuracy. Additionally, the DLA20-ACA5-1-AC1-B features a high accuracy of 0.2 % linearity, making it suitable for a variety of industrial applications where accuracy is critical.

The working principle behind the DLA20-ACA5-1-AC1-B is based on the principle of analog signal conversion. This is accomplished by way of a voltage-to-current converter, which takes a given input voltage and converts it into a corresponding current signal. This current signal is then applied to the panel meter, which will then display the corresponding output signal. This output signal can range from 4-20 mA, which is the usual range for most panel meters. This output signal can then be used to display the readings of various process variables, such as pressure, temperature, and flow.

In terms of design and construction, the DLA20-ACA5-1-AC1-B is constructed from a stainless steel housing, with an anodized aluminum bezel. Additionally, the unit has a 4-20 mA output signal, as well as an adjustable mounting bracket for easy installation. This makes it suitable for mounting in environments where general vibration, as well as extreme temperature and humidity levels, can be expected. Additionally, the panel meter is also designed to meet the stringent requirements of ATEX, CSA, and IECEx. This makes the unit suitable for use in hazardous locations, where explosive gases may be present.

In terms of installation, the DLA20-ACA5-1-AC1-B is fairly simple to install. All that is required is a power connection, as well as a 4-20 mA signal from the process control system. This signal is then connected to the panel meter through the 4-20 mA terminals. Additionally, calibration is also performed simply, by adjusting the potentiometer on the panel meter.

To conclude, the DLA20-ACA5-1-AC1-B is a type of panel meter that can be used for process control in hazardous locations. It features a 4-20 mA output signal, and has a high accuracy of 0.2% linearity. Additionally, it is constructed from stainless steel and an anodized aluminum bezel, and can easily be installed and calibrated. As such, it is suitable for a variety of industrial applications where safety and accuracy are of paramount importance.
