THERMOVAC TM 101 Vacuum Gauge – Flexible, Rugged & Reliable Vacuum Measurement
The temperature compensated hand- held THERMOVAC TM 101 is equipped with a Piezo/Pirani combination sensor and capable for total pressure measurement in the range of 1200 to 5·10-4 mbar.
The instrument can also be operated completely under vacuum conditions. The pressure is displayed continuously over the whole measurement range.With the integrated memory-function it is possible to store and display up to 2000 measured values.
- Measurement range 1200 to 5 x 10-4 mbar (7 decades)
- Usage possible directly within a vacuum chamber
- Data logging via USB interface and internal memory for up to 2000 measured values
- Online measurement via USB possible; measuring data exportable
- Cordless power supply with standard 9 V battery or 12 V AC adapter
- Pressure unit selectable amongst mbar, Torr and Pascal
- Windows software VacuGraph for measuring data storage and PC analysis (optional)
- Mobile and fixed vacuum pressure measurement installations of all kind (service, maintenance, universities, laboratory)
- Food and packaging industry
- Vacuum process quality assurance
- Visualisation and documentation of vacuum pumps and systems
The TM 101 provides high resolution covering the complete measurement range due to the usage of two different physical sensor principles.
The TM 101 is equipped with an internal piezo-resistive sensor for measurements in the rough vacuum range. Under pressure a thin diaphragm is flexed, whilst a resistor bridge is applied on the back. The variation in resistance appearing thereby is subject to the applied total pressure.
The internal Pirani sensor applies in the fine vacuum range, using the thermal conductivity of gases for the vacuum measurement. The filament is heated to a constant temperature in a bridge circuit. The necessary bridge voltage is subject to the total pressure measurement.
The Piezo/Pirani combination sensors measures >15 mbar independently of the type of gas. In the lower measurement range the adjustable gas correction factor permits a measurement.
