TH1M and TH2M

The one channel amplifier TH1M outputs one voltage which is proportional to the connected type K thermocouple’s temperature. The dual channel amplifier TH2M outputs two voltages which are proportional according to the connected two type K thermocouple’s temperatures.

The amplifiers amplify the voltage difference which is caused by the difference between the thermocouple’s temperature and the amplifier’s temperature. The amplifier’s temperature is internally measured and the output signal is correspondingly compensated.

There are 3 temperature ranges:

Range 1: -25 °C … 1150 °C (4 mV/°C)

Range 2: -40 °C … 430 °C (10 mV/°C)

Range 3: -45 °C … 190 °C (20 mV/°C)
