Panel Meters
Panel meters mount into a control panel or enclosure to give operators a continuous, at-a-glance reading of voltage, current, temperature, or process signals. We stock analog panel meters with a moving needle and dial, digital panel meters with LED or LCD displays, and process meters that add setpoint control and relay outputs for alarms and automation. Choosing between them starts with the input signal, DC voltage and current, AC true RMS, thermocouple or RTD temperature, or a 4-20mA process signal.
Digital panel meters convert an analog input through an ADC and display the value with higher accuracy than a moving needle can match, which makes them the standard choice for automation and energy monitoring. Analog meters still hold an edge for quick visual trend checks and installations where scanning many devices at a glance matters more than exact precision. Most digital models fit standard DIN cutouts, from 1/32 DIN up to 1/4 DIN, so panel space narrows the field quickly.
Types of Panel Meters
Analog panel meters display a reading with a moving needle against a calibrated dial, needing no external power and offering reliable performance in high-vibration environments. Digital panel meters convert an analog signal through an ADC and show the value on an LED or LCD display, delivering higher accuracy and easier integration with control systems. Process meters and controllers add setpoint adjustment, relay outputs, and sometimes PID control, letting the meter trigger alarms or drive a process directly rather than just displaying a value. Multimeter-style panel meters combine amp, volt, and frequency measurement in one unit, often with CT or shunt inputs for current sensing.
Common Applications
- Control panel and switchgear monitoring
- Process control and SCADA/PLC integration
- Energy and power monitoring
- Machine and equipment status indication
Choosing the Right Panel Meter
Start with the input signal type, since it determines the required signal conditioning, then match DIN size to your available panel space and decide whether you need relay outputs or digital communication like Modbus for automation integration.

Frequently Asked Questions
What’s the difference between an analog and a digital panel meter?
Analog meters use a moving needle against a dial and need no external power, while digital meters convert the signal through an ADC for a more precise numeric display and easier integration with control systems.
What does DIN size mean for a panel meter?
DIN size refers to a standardized cutout dimension, ranging from 1/32 DIN to 1/4 DIN and larger, that determines what size hole you need to cut in your panel to mount the meter.
What is a 4-20mA process meter used for?
A 4-20mA process meter reads a standard industrial current loop signal from a transmitter and scales it to display an engineering unit like pressure, flow, or temperature.
Do panel meters need external power to operate?
Analog panel meters typically don’t, since they read the measured signal directly, while digital and process meters generally require external power to run their display and internal electronics.
