Nokeval Loop Powered Panel Meters
The auto powered panel meter features a bright red LED display and requires no external power supply. It utilises a current signal of 4-20 mA to provide the necessary energy, making it suitable for installations where auxiliary power is unavailable. With its superior visibility, the meter offers an upgrade from LCD displays.
There are two models available: the basic model 201 without alarms, and model 202 with two alarm contacts. Display scaling and configuration can be easily adjusted using the front panel buttons. The unit includes a digital filter to ensure stability in the 4-digit display.
Model 202 allows the configuration of two optional alarms, both high and low. Password protection is available for entering configuration and alarm stages. The front panel is protected with an IP65 rating.

What is a Loop Powered Panel Meter?
A loop powered panel meter is a device used for measuring and displaying process variables, such as temperature or pressure, in industrial applications. It is powered by the current loop signal (typically 4-20 mA) that carries both the measurement information and the power required for the panel meter’s operation. This eliminates the need for a separate power supply for the panel meter, simplifying installation and reducing wiring complexity.
