Introduction to Analog and digital Panel Meters
A panel meter is an instrument that displays an input signal in either a digital or analog form from a sensor or a transmitter
. Many panel meters also include alarm options
as well as the ability to connect and transfer data to a computer. OMEGA's iSeries digital panel meters are available with an ethernet option which
allows the indicator reading to be accessed across a local area network (LAN) or even through the internet.
Since panel meters are generally mounted inside an instrument panel, the panel must be cut to accommodate the instrument. In order to
provide interchangeability between digital meters, most panel meters are designed to standard DIN sizes. The most common DIN sizes are shown below.

Temperature and Process Panel Meter
The most common types of meter is one that accepts a single input and provides a digital display of the signal.
These digital meters typically accept inputs from temperature sensors such as thermocouples and RTDs as well as process signals such as 4-20 mA, 0-5 Vdc and 0-10 Vdc.
A totalizer is a type of panel meter that provides a summation over time of the input signal. Totalizers are commonly used with
pulse inputs to provide a count of the number of pulses. This is typically used in flow measurement applications.
Large Display Panel Meters
Large display meters are commonly used when the display must be visible at a distance. OMEGA's ILD series
features digits as large as 4 inches in height.
Multi-Input Indicators and Scanners
OMEGA offers several panel meters that can accept more than one input. Some meters can switch from one channel to the
next by pressing a button on the front of the meter while others will automatically scan through a series of channels.
OMEGA's CN612 can accept up to 12 temperature inputs.
OMEGA offers panel meters built into a benchtop case. The benchtop case provides portability and is
commonly used in laboratory applications.
At one time most meters were analog style, however, with the advent of digital technology analog meters have become
rare. Analog meters are dial type gauges, like the speedometer in most cars. However there are some applications
which still dictate analog meters.
