VACUUM GAUGE – ANALYTICAL INSTRUMENTS

________

Vacuum gauges for electron microscopy and analytical instruments

VSP841 – Passive Pirani vacuum sensor for spectrometry 

•     Passive vacuum gauge with long time stability
•     Durable vacuum sensor, elastic helix filament
•     Vacuum sensor pre-adjusted
•     Extremely small sensor volume
•     Screwable, electric connector of the vacuum gauge
•     Proposal for evaluation circuit available on request

Ideally suited for:

• XRF spectrometry

SMARTLINE VACUUM GAUGES FOR ANALYTICAL INSTRUMENTS:

VSM combination sensor vacuum gauge with Pirani / Cold cathode sensor

• Resilient vacuum transducer with patented pulsed Pirani sensor with extended lifetime
• RS485 interface, signal output 0 – 10 V, logarithmic
• Vacuum gauge sensor head is easily replaceable
• Dry relay switch points, independent from each other

VSP Vacuum gauge with Pirani-sensor

• Very good reproducibility, accurate measurements with optimal compensation of temperature
• Ample measuring range 1000-1e-4 mbar
• Vacuum gauge with high resolution and accuracy
• Vacuum gauge is adjustable by one button click
• Durable Pirani vacuum gauge

VSH combination sensor Pirani / Hot cathode sensor (Bayard-Alpert)

• Vacuum gauge with a patented pulsed Pirani sensor – the extended range allows use of the hot cathode at a lower pressure and therefore increases the lifetime of the vacuum sensor
• Outstanding repeatability as well as accuracy
• RS485 interface, signal output 0 – 10 V, logarithmic
• The sensor heads of the unit are replaceable and bakeable up to180 °C without electronics
• Double filament Bayard-Alpert gauge – if one filament fails, the gauge will automatically switch to the backup filament
• Dry relay switch points, independent from each other
• Accurate pressure readings due to separate gas type correction factors for hot cathode and Pirani sensors

Matching display and control units:

• VD12 – Dual channel vacuum display and control unit
• VD14 – Four channel vacuum display and control unit

Ideal suited for:

• Vacuum gauge for electron microscopy
• Vacuum instruments for optical spectrometry
• Vacuum gauge for LC / MS
