Any vacuum system that requires pressure measurement over a wide range. The WEG with AGD represents a very simple and extremely cost-effective means to achieve this.
The linear output and balancing make the WRG an attractive option for industrial 0EMs where vacuum gauges may be integrated directly into the process controller.
The WEG is suitable for use in a wide range of y and UV applications. However, if the process spends a lot of time between 5×10-4 and 5×10-3 mbar, Edwards recommends the use of standalone APG100 Pirani gauges and AIM Penning gauges, as this will improve the gauge’s availability in the application. Functional Advantages.
Microprocessor signal processing allows seamless switching between Pirani and magnetron outputs as well as linear outputs (recorded pressure scale).
D-Type includes cable strain relief and enhanced dust protection – IP44
Low magnetic field version (SL) for sensitive applications such as mass spectrometry and electron microscopy
Easily programmable setpoints cover the entire measuring range
Highly reliable discharge using magnetron technology, even in high vacuum or relatively contaminated environments, for automatic vacuum setting of the Pirani gauge element
Single push-button atmosphere setting
Extended service intervals and gauge life due to reduced HT voltage after ignition and low discharge current Extremely compact construction with recessed electrical connectors
Easy to service; both Pirani and magnetron elements can be replaced individually
Comprehensive failure mode diagnostics
