Passive Vacuum Sensor Absolute Pressure 1000...100 to 1 x 10-3 mbar The VSP841 and VSP842 Pirani half bridges measure absolute pressure in the fine vacuum range. The robust heat conduction sensor is compact, preadjusted and temperature compensated and is suitable for controlled and passive bridge circuit. Typical Applications • Appliances with integrated electronics for regulation and evaluation • Economical Pirani sensor • Compact dimensions • Long time stability • Lockable, electric connector • Apparatus engineering • Durable sensor, elastic helix filament • Optionally with cap to protect the sensor against dust and humidity • Filament protected from condensing solvents by a metal screen • Sensor pre-adjusted • Analysis instruments • Chemical process engineering • Freeze drying • Monitoring of vacuum insulations • Concentrators • Extremely small sensor volume • Temperature sensor integrated • Vacuum connection by stainless steel small flange DN 16 ISO-KF (VSP841) or 1/8" NPT male thread (VSP842) • Proposal for eval
