For cable lengths up to 5 m (0.34 mm conductor cross-section) the out- put signal can be measured directly between the positive signal output (Pin 2) and supply common (Pin 5). At greater cable lengths, differential measurement between signal output (Pin 2) and signal common (Pin 12) is recommended.

4 Operation 4.1 Measuring Principle, The BPG402-Sx vacuum gauges consist of two separate measuring systems (hot cathode Bayard-Alpert (BA) and Pirani). Measuring Behavior Bayard-Alpert The hot cathode measuring system uses an electrode system according to Bayard- Alpert which is designed for a low X-ray limit. The measuring principle of this measuring system is based on gas ionization.

However, filament selection can be commanded via the interfaces (→ 29, 31, [1], [2] and [3]). INFICON recommends the replacement of the sensor as soon as the first filament failure has been detected. The replacement can be carried out during an appropri- ate off time such as the completion of a process or a planned maintenance brake.
4.2 Operational Principle of The analog measuring signals of the Bayard-Alpert and Pirani sensors are con- verted into a digital form by a micro-controller and subsequently converted to a the Gauge value representing the measured total pressure. After further processing this value is available as analog measurement signal (0 …...

4.7 Emission Control Mode General The emission control mode function defines the rules by which the emission of the gauge is switched on and off. The manual mode feature has a positive effect on gauge live time, mainly in process situations where the process chamber has to be vented frequently.

The physical interface and communication firmware of BPG402-SD comply with the DeviceNet standard (→ [5], [7]). Two adjustable switching functions are integrated in BPG402-SD.
