Combustible Gas Transmitter

Sieger Digi-CatCombustible Gas Transmitter

Sieger Digi-CatCombustible Gas TransmitterFeatures• Non-intrusive one person calibration– reducing downtime and maintenancecosts.• Linear 4 – 20mA output signal – industrystandard compatible with dedicatedcontrol equipment or plant controlsystems.• LED display – local indication of gasconcentration.• CENELEC and other certification– suitable for hazardous area installation.• Remote sensor mounting – ease ofcalibration for inaccessible areas.Applications• Petrochemical.• Pharmaceutical.• Chemical.• Manufacturing.• Aerosol Filling..The Digi-Cat is designed to interface witha catalytic sensor and has a conventional4 – 20mA output. The output may be selectedby means of a link to be floating, currentsource or current sink. The input to the unitis a resistive bridge input.
