Temperature Scanners TempScan 15101

The panel mounted Digital Temperature Scaneers (TempScan 15101) are designed to monitor temperature of RTD or T/C sensors with 2 alarms. The instruments are designed with CMOS ICs and incorporate a relay based multiplexer to select a sensor. A signal-conditioner with open-sensor detection and necessary linearisation processes the output of the scanned sensor. These scanners can operate in Auto and Manual modes.
