Edwards D14701000 WRG-S-NW25 Active Wide Range Gauge
Product Description
Edwards D14701000 WRG-S-NW25 Active Wide Range Gauge
Pressure Range Atmosphere to 10-9 mbar/Torr Accuracy Typically ± 15% < 100 mbar and ± 30% < 10-3 mbar Adjustments Atmosphere and Setpoint
Features
- Single push-button atmosphere setting
- Ultra compact, featuring recessed electrical connector
- Easy service; both Pirani and magnetron elements are individually replaceable
- Comprehensive failure mode diagnostics facility
- Compatible with Edwards TIC, TAG and ADC controllers
- Magnetron uses an advanced technique for highly reliable striking, even at high vacuum or in relatively contaminated conditions
- Automatic vacuum setting of Pirani gauge element
- Easily programmed set point covering entire measuring range
- Extended service intervals and gauge lifetime, through reduction of HT voltage after ignition and low discharge current
- Microprocessor signal processing gives seamless transition between Pirani and magnetron outputs as well as linear output (log pressure scale)
The Edwards D14701000 WRG-S-NW25 Active Wide Range Gauge is a compact and efficient solution for pressure measurement across a wide range, from atmospheric pressure to 10-9 mbar. This gauge is highly adaptable, halving the space and connectivity hardware typically required, which is crucial for many applications. It features an innovative striker technology and easy-to-use push-button calibration and set point controls, enhancing its usability and integration into system controls. The gauge is particularly effective in applications requiring rapid pump-down from atmospheric to high vacuum levels. It includes comprehensive diagnostics for failure modes, and both its Pirani and magnetron elements are individually replaceable, ensuring easy maintenance. Compatible with Edwards TIC, TAG, and ADC controllers, the gauge uses advanced techniques for reliable magnetron striking in various conditions. Additionally, it boasts extended service intervals and lifespan by reducing HT voltage post-ignition and operating at low discharge currents, with a microprocessor that ensures smooth transitions between outputs and a linear output on a logarithmic pressure scale.
INCLUDED: The Edwards D14701000 WRG-S-NW25 Active Wide Range Gauge includes:
- Manufacturer's Documentation
- 1 Year Manufacturer's Warranty
