Process indicators are used for display and/or control of
process variables in applications that use analog signals
representing pressure, temperature, weight, etc. Our
Dynapar brand instruments are especially well suited for
analog-input measurements in industrial environments.
Danaher Controls' leadership in designing products
suitable for severe industrial environments ensures the
highest level of value and performance.
DIGITAL PANEL METER FUNCTIONS
DC Volt Meters will display in proportion to the voltage
applied to the input. Several input ranges allow their use
in a variety of applications. In the lowest range, DC volt
meters can replace old analog meters and provide more
resolution and accuracy. Through the use of a shunt
(resistor), DC volt meters can also be used to display
motor load currents. The middle ranges accommodate
operator input devices or process control electronics. On
the high range, these meters can readout power supply
or DC motor voltages.
DC Current Meters are popular when noise interference
can disrupt voltage levels and are common signals used
to drive old analog meters. Reference outputs of 0 to 1
mA, 0 to 5 mA, and 0 to 10 mA which are proportional to
motor speed are also available from some AC drives.
Process Volt Meters and Current Loop Indicators
operate similar to DC voltage and current meters, but
include more extensive span and zero adjustments.
Some popular signal ranges include –10 to +10 VDC, 4
to 20 mA and 10 to 50 mA current loops. These sensors
are popular in industrial environments when their signals
must be reliably transmitted over large distances, or
when the signal is needed by more than one device. The
minimum and maximum signal levels require adjustments
at both ends of the range in order to provide a meaningful
display.

DISPLAY TYPES
Light emitting diode (LED) and liquid crystal displays
(LCD) are two popular choices for digital display of
numeric information. Our products are offered in a
range of price and size selections, in addition to the
display type.
LED’s can be viewed in very dimly lit areas since they
produce their own light. Their high contrast presentation
makes them the preferred type when the display must
be observed from a distance.
LCD’s are best suited for installation in areas where
there is reasonably good lighting. They are superior to
most other display types when viewed in very bright
ambient light, such as direct sunlight. Our S628
AWESOME Series feature an LED display that can
change color when an alarm or limit is reached.
SPECIFYING A DIGITAL PANEL METER
The selection of an LED or LCD display is dictated by
the amount of ambient light in the area. LCD’s are
better suited to sunlit environments while LED’s work
well in dimly lit areas. LCD displays usually come in
smaller package sizes and are often chosen when
space constraints are present.
Applications require a certain display range, which is
determined by the number of digits. For example, a 3-1/
2 digit panel meter can indicate value to ±1,999. A
7200 RPM motor speed indicator would require a 4-1/2
digit meter whose range is ±19,999. For process control
signals, the minimum display may not be 0. Zero
adjustments allow the minimum signal level to be set to
indicate the value desired while Span adjustments
handle the maximum level.
Finally, other convenience features should be consid-
ered. Setup and calibration methods can be potentiom-
eter adjustments or switch settings. Accessory power
may be needed to power sensing devices.
