Devar's 3011 series of  strain gage, temperature and indicator controllers accept temperature  inputs J/K/T/E/R/S/N/B type thermocouples  and strain gage millivolt inputs between +/-125mV. To measure temperature simply specify the thermocouple type and C or F. Thermocouple curves are linearized displaying the temperature with +/-0.2°C.

Strain gage measurements are made by connecting the 4 wire bridge directly. The unit is calibrated by applying the desired min and max mV range to the meter and configuring what is to be displayed in engineering units. All programming is done via the front keypad. The +/-10V excitation supply may power up to four 350 Ohm cells.

The 3011 series is housed in an 1/8 DIN aluminum housing with a splash proof front panel. The six digit 0.54" high LED display provides easy viewing under all ambient light conditions and it's 14 segment alphanumeric display provides plain English prompting during configuration. Five active characters display process values between 99999 and -19999. The sixth character displays a C, or F when measuring temperature, a zero when measuring temperature, a zero character description such as a (#).
