Description
These
large digit process indicators feature a
large-digit, 4-digit (±9,999)
flip digit display which can be scaled for
readout in engineering units such as PSI,
GPM, or degrees. Depending on the model,
the signal may be a DC voltage (1-5 V,
0-10 V, etc.), a DC current loop (4-20 mA,
0-20 mA etc.), or a frequency (30 Hz
to 10 KHz). The units are microprocessor
controlled. Broad Range Scaling is
accessible from the front by removing an
access plug.
Exceptional
viewing distance, even outdoors in bright
sunlight, is achieved with large, 4", 6"
or 9"
tall, fluorescent yellow electromagnetic
flip digits. The sealed surface-mount case
provides protection for dirty or damp
environments. Please see our
Mechanical Section for dimensions. Standard power is 115 Vac.
Options include
230 Vac power, 12 Vdc power, 24V dc
excitation voltage output to power
transducers, special scaling, decimal
points, and low temperature operation.
An 18-Month
Warranty is standard.
