Which advantages does the “ramp-impulse method” offer against the standard Pirani sensor?
The patented “ramp-impulse method“ measures conductivity by timing the duration of heating of the Pirani filament. It works at lower filament temperatures, therefore uses less power and offers a wider measurement range.
Is the Pirani sensor protected against pollution and dirt?
All Thyracont pirani sensors are fitted with a cover which protects against basic condensation and pollution. If the sensors are used in an extremely polluted environment, it is advised to additionally either use an extension pipe, an elbow fitting, a cooling trap or a seal ring with a sinter filter
Is it possible to clean the Pirani sensor?
Depending on the type and intensity of the pollution, it is feasible to clean the sensor with isopropanol. To do this, you need to fill the measuring cell completely with isopropanol and let it rest for a few minutes. After removal of the fluid it is necessary for the cell to completely dry out. Please note that e.g. oil debris is baked onto the filament and is very tough or even impossible to clean.
Do I have to mount the instrument into a specific position?
Basically the instruments can be mounted in every position. The best accuracy is achieved if the flange of the instrument is mounted vertically, because the instruments are calibrated in this position. Also it is not recommended to mount the sensor at the bottom of a pipe, because condensate and dirt could be collected in the sensor cell.
How often do I need to recalibrate the vacuum transducer?
This depends on the specific application. Especially if there are coatings and contaminations on the sensor-head or if it is used in extreme temperature conditions it can be necessary to readjust the instrument. For quality assurance matters, we recommend to return the instrument for calibration every one or two years. We can offer a test certificate (item no. TEST) or alternatively a works calibration (item no. ADJCERT).
