Heated High-Voltage Displacement Meter (HB-PTB) or (HVDM II)
The Heated High-Voltage Displacement Meter - with designations HB-PTB or HVDM II - extends the capability of the High-Voltage Displacement Meter (HVDM) by adding electronics that combine an Philtec displacement sensor and a heater element that is controlled directly by the Vision program, through a separate USB channel.

Safety
The HB-PTB can reach internal temperatures or 230° C. Do not open the test fixture or attempt to touch your sample or internal parts of the HB-PTB before allowing the instrument to cool completely. The Vision Read Temperature Task can be used to monitor the internal temperature of the instrument.
Recalibration
Note that when operating over a range of temperatures, the Philtec displacement sensor will need to be repositioned after every temperature range to return the output to the 5.0-Volt position. This is the result of thermal expansion as the temperature changes. This requires supervision of an experiment that is being conducted over several temperatures. Future improvements to the HVDM are planned that will automatically keep the Philtec sensor positioned for optimal output.
