Industrial Digital Panel Meters & Signal Converters

Monitoring critical process variables requires instrumentation that is both highly accurate and clearly legible from a distance. Our digital panel meters and signal converters are designed for harsh factory automation environments, providing real-time data visualization for voltage, current, temperature, and frequency.

Upgrading from analog needle gauges to our digital meters eliminates parallax errors and provides exact numeric readouts. Advanced models include programmable setpoints, relay outputs for automated control (e.g., triggering alarms or shutting off pumps), and serial communication interfaces (RS-485, Modbus) for seamless integration into centralized SCADA or PLC systems. Our signal converters complement these meters by translating noisy or incompatible field signals (like raw thermocouple millivolts or varying frequencies) into clean, standardized 4-20mA or 0-10V analog signals.

Selecting the Right Panel Meter

Input Type Typical Application Key Feature to Look For
Process (4-20mA / 0-10V) Pressure, flow, and level sensors in fluid processing. Loop-powered operation (no separate AC/DC supply needed).
Temperature (TC/RTD) Industrial ovens, chillers, and HVAC monitoring. Built-in cold junction compensation and linearization.
AC/DC Voltage & Current Power distribution panels, motor load monitoring. True RMS measurement for distorted AC waveforms.

Frequently Asked Questions

What is a "Loop-Powered" meter?

A loop-powered panel meter draws its operational power directly from the 4-20mA signal loop it is measuring. This eliminates the need to run separate power wires (120VAC or 24VDC) to the meter, simplifying installation and reducing wiring costs.

Can these meters trigger external alarms?

Yes, many of our digital panel meters can be equipped with optional relay output cards. You can program high and low setpoints via the front panel to trigger alarms, strobe lights, or shut down machinery if parameters exceed safe limits.

What is the standard cutout size?

The industry standard for panel meters is the 1/8 DIN size (92mm x 45mm cutout). We offer meters in 1/8 DIN, 1/16 DIN, and custom miniature sizes to fit your specific enclosure requirements.
