The HGSI TCA-MS-K-8-A4 EGT Probe Thermocouple Amplifier Module functions to convert the low output voltage signal from up to 8 Type K thermocouple probes into 8 independent linearized 0 to 5 VDC output voltages. This output is ideal for interfacing to dataloggers, aftermarket ECU's, temperature indicators, chart recorders, controllers, or other instrumentation equipment.
Temperature Measuring Range: -193 to +2282°F (-125 to +1250°C)
Output Scale Factor: 2.2 mV / °F (4.0 mV / °C)
