9.20 PT100 Temperature Sensor Replacement
The temperature sensor is located below the chamber at the front. It is
mounted in a fitting (1) that is part of the chamber drain system (see
picture below).
Caution!
Before starting, disconnect the instrument from the power source
and ensure that there is no pressure in the autoclave’s chamber
and jacket.
1. Take off the autoclave cover (see para. 9.2 “Removing the Outer
Covers of the Autoclave”).
2. Unscrew the nut (3) attaching the sensor (2) to the fitting (1).
3. Remove the sensor from the fitting.
4. Disconnect the sensor’s wire (4) from the electronic box and
remove the sensor from the autoclave.
5. Install a new sensor. Ensure that the tip of the sensor is positioned
at, but not past the center of the nipple attached to the chamber.
Any other positioning will result in an inaccurate reading.
6. Connect the sensor’s wire to the electronic box.
7. Reassemble the cover.
8. After any replacement or repositioning recalibrating the machine is
necessary (see sec 5)
