NoShok 820 Series digital indicators provide electronic temperature measurement and a solution for most industrial temperature monitoring and indicating applications. The gauges features an bright large 4-digit red LED display and an analog 4-20mA output. The 820 series is an ideal replacement for bi-metal, liquid bulb and gas thermometers, they are also suitable to replace Mercury reduction programs. The indicator comes factory scaled and calibrated to the specific temperature range. No costly field calibration is needed. If the application changes the temperature indicator can be re-scaled and re-calibrated using the optional interface module and software must be at any range within the sensor limits and it will maintain its accuracy.
The 820 series housing, probe and fitting are constructed of 316 stainless steel and is rated to NEMA 4X (IP65) with M12 x1 (5-pin) electrical connection.
