-40 to +85°C Operating Temperature (Optional)
Made in the USA, these Newport LCD indicators provide
extensive zero and span adjustment capability, so the units can
read out directly in percent or in engineering units for process
variables such as pressure, flow, temperature, or level. The liquid
crystal display provides 3 1/2 active digits, two-jumper selectable
dummy right hand zeroes, and five programmable decimal points.
The 508B series, in the NEMA-4 die-cast metal housing, is
weatherproof to 5 PSI, with a temperature range of -40°C to
+85°C. The popular 558B series fits a 1/8 DIN panel cutout.
Electrical connections are via a three-pole male header connector
on the circuit board and a removable mating plug-in socket
connector with screw clamps, allowing for easy and reliable
electrical connections.

The LPM4200 Loop Powered Indicators are
ideal for areas where local readout of a
process variable is required and ease of
viewing is important. Powered by the 4 to 20
mA loop, they drop only 2.7 volts from the loop
being monitored. These meters are easy to
