Setting up TH Thermometer Amplifier and Sensor
The TH amplifier and its sensor are designed to measure the temperature of the fluid
perfusing a heart or an organ (liver, kidney, mesentery) in order to determine the
temperature of the organ.
Fig. 6—The TH Temperature Amplifier, front and back.
If the temperature sensor is going to be used:
1. Plug the microphone jack on the end of the temperature sensor to the
TH IN
socket on the back panel of the amplifier. The sensor is now connected to the
TH amplifier module.
2. Plug the microphone jack of one of the output cables into the TH OUT socket of
the TH pressure amplifier. Connect the other end of the output cable to one of
the analog inputs of the data acquisition unit.
3. Turn the 3-way program switch to GND . Place the temperature probe on or into
the area where the temperature needs to be measured. Turn on the amplifier
unit. The actual temperature of the area being monitored appears on the 3-digit
display on the front panel of the TH module.
4. Check the baseline level of the temperature recording channel. A signal of
zero (0) volts is sent by the amplifier to the data recorder. If necessary, set the
baseline of the recording channel to zero (0) using the controls of the data
recording system.
5. Turn the 3-way program switch to the 45ºC position. The voltage level on the
recording channel should change from 0 to 450mVDC corresponding to the
programmed 0-45ºC temperature range.
6. Turn the program switch to MEAS . The voltage level on the recording channel
should now correspond to the actual temperature at the location of the sensor.
