Loop-Powered Gauges
Gauges can be powered by
any 8 to 32 VDC source for lowvoltage operation or use as a
transmitter with an analog 4
to 20 mA output. Units feature
a rugged, epoxy-coated extruded
aluminum case, rear cov
er with ABS/polycarbonate
front bezel, and front-accessible
calibration adjustments. Test
level adjustment and push
button allow output to be
checked. Include a 3-ft (1-m) L,
two-conductor 22 AWG cable
with stripped ends.
