Miniature linear thermocouple amplifier

The MicroTC Linear Thermocouple Amplifiert provides:

  1. A standard miniature female thermocouple connector
  2. Solder terminals on the back for easy connection for power and signal
  3. A cold junction compensation and amplifier for a thermocouple signal to a linear 5 mV/°C over a measurable range of -50 to +400°C The measurable range expands to -200 to 1360°C with the use of post-processing polynomials. The amplifier accepts a wide power supply range (7 à 16 VDC), and separate configurations are available for dual or single power supplies.

The drift is extremely low, no recalibration is required. The zero and the range can be adjusted within ± 3% to enhance the accuracy. The setup is completed with the help of potentiometers located below the unit.


Thanks to a miniature and light housing (5g only), and a thru-hole in the center of the unit, MICRO-TC can be glued, screwed to a surface or tied to the mating connector. The thermocouple plugs directly into the unit, the signal output and the power voltage wires are welded on solder terminals.
