Model INFCS-100 Shown

The INFINITY C process meter is a low-cost high performance process indicator. Four full digits and broad scaling capability allow for display in virtually any engineering units. A wide variety of DC voltage and current input ranges cover any typical process application. Excitation for transducers or transmitters is provided on every unit. Digital tare function from the front panel and remote is included on every unit. A hardware lockout prevents unauthorised changes in setup.
The INFINITY C strain meter is ideal for use with pressure transducers, load cells, or any strain gauge type transducers. The strain meter has all the standard features of the process meter plus it accepts ratiometric inputs and has a front panel NET/GROSS feature for weighing applications.
