Model PI 700 is a 4 digit (19,999 count) industrial process indicator with large, bright, 2" (57 mm) tall LED digits legible at up to 75 feet (23 m). It is designed to read out directly in engineering units, such as PSI, GPM or degrees, when placed in series with a 0-20 mA or 4-20 mA current loop. Scaling adjustments and decimal point selection are accessible from the front by removing an access plug.

The sealed surface-mount case provides protection for installation in dirty or damp environments. Three mounting methods are provided for: thru-panel mounting, raised surface mounting, or flush surface mounting. Electrical connections are via screw terminals. Please see our Mechanical Section. Standard power is 115 Vac.

Options include 230 Vac power, an excitation output adjustable from 1.3 to 24 Vdc to drive transducers, an analog output of 1 mV count to drive recording devices, and a NEMA-4 enclosure.

A Two-Year Warranty is standard.
