Measurement Principles
Select the PV201 for piezo-based precision or the TM201 for broader measurement with piezo and Pirani technology. Both models support system integrity and operational efficiency. The main differences between them are:
PV201 (Piezovac)
The PV201 utilizes a piezoresistive sensor for high-pressure measurements. This sensor detects changes in electrical resistance as pressure is applied, providing highly accurate readings for absolute pressures up to 2000 mbar. Ideal for applications requiring precise high-pressure measurements, the PV201 ensures reliable performance in various vacuum environments.
TM201 (Thermovac)
The TM201 combines a piezoresistive sensor for high-pressure measurements with a heat conducting Pirani sensor for low-pressure measurements. The Pirani sensor measures the thermal conductivity of the gas, which varies with pressure, allowing for precise measurements down to 5 x 10⁻⁵ mbar. This dual-sensor approach makes the TM201 suitable for a broader range of vacuum applications, from ultra-high to rough vacuum conditions.
