TCA01 User Manual
The Solid-Motion TCA01 is designed to amplify and filter
small thermocouple voltage
and output signals. The output of the TCA01 ranges from 0 to 10V and
may be connected
to an analog-to-digital converter (ADC), such as a Dataq, for digitization
and display on a
PC.
A battery voltage of anywhere from 12V to 15V may be used to power the
TCA01.
Features
- Cold junction compensated
- ±0.5șC linearity
- 10Hz 2-pole butterworth output noise filter
- 0-10V output. 0-5V output also avalible
- Diode protected battery connection. Accidently reversing the supply connection won't destroy the amplifier
- Supply voltage 12V to 15V
- Custom gains and bandwidths on request.

Troubleshooting
If no signal shows up in the Dataq oscilloscope with a thermocouple
connected, try these
fixes:
1. Make sure the supply voltage is at least 12V.
