Overview

Edward WRG active wide range vacuum gauge WRG-S-NW25 from the UKProvide single interface pressure measurement results at pressures ranging from atmospheric pressure to 10-9 mbar, and provide linear output. It is a compact solution that reduces the required space and connecting hardware by half, which is a significant advantage for many applications. WRG has many novel features, including new discharge devices, button calibration, set point control, and comprehensive diagnostic functions. WRG is an economically efficient vacuum management solution that can be used in conjunction with Edwards controllers or directly integrated into system control.Edward WRG active wide range vacuum gauge WRG-S-NW25 from the UK

application

• Any vacuum system that requires measuring pressure over a wide range. WRG with AGD represents a very simple and highly cost-effective means to achieve this goal.
  

• For industrial OEMs who may need to integrate vacuum gauges directly into process controllers, linear output and balancing make WRG an attractive option.

• Edward WRG active wide range vacuum gauge WRG-S-NW25 from the UKSuitable for use in various HV and UHV application fields. However, if the process takes a significant amount of time between 5x10-4 and 5x10-3 mbar, Edwards recommends using independent APG100 Pirani vacuum gauges and AIM Penning vacuum gauges, as this will improve the reliability of the vacuum gauges in applications.Edward WRG active wide range vacuum gauge WRG-S-NW25 from the UK.

Features and advantages

• The microprocessor signal processing allows seamless conversion between Pirani and magnetron outputs as well as linear outputs (recording pressure scales).

• D-type includes cable strain relief and enhanced dust protection - IP44.

• Low magnetic field type (SL) is suitable for sensitive applications such as mass spectrometry analysis and electron microscopy.

• The easily programmable set points cover the entire measurement range.

• Magnetrons use advanced technology for highly reliable discharge, even in high vacuum or relatively polluted environments.

• Automatically set the vacuum for Pirani vacuum gauge components.

• Single button atmospheric setting.

• By reducing the HT voltage after ignition and using low discharge current, the maintenance interval and vacuum gauge life have been extended.

• The structure is extremely compact, using recessed electrical connectors.

• Easy to repair; Both Pirani and magnetron components can be replaced separately.

• Comprehensive fault mode diagnosis device.
