Large 1" Digit Loop Powered Process Indicators
The LPM4200 series of large digit
loop powered indicators is designed for
areas where a local readout of a particular
process variable is required and ease
of viewing is important. Powered by the
4 to 20 mA loop, these meters drop only
2.7 volts from the loop being monitored
and can be scaled to readout directly in
the engineering units desired.
The Martel Loop Panel Meter,
LPM-420, is an easy to install, loop powered
panel meter offering accuracy of
0.05% FSR, above average stability, and
an operating temperature range of -20°C
to +65°C.
Accepting inputs from 4 mA to 20 mA,
the loop panel meter can be scaled to display
a wide range of engineering units for
monitoring process current loops.
For cost effective mounting flexibility,
a variety of housings are available to
fit most requirements.
