GDS - 10 - Single Point Gas Sensor - Datasheet

GDS10ApplicationA fixed gas sensor that meets the requirements for economic and reliable monitoring of gaslevels in a wide range of environments and applications.Initially designed for the monitoring of gases within cabins, enclosures and cabinets the additionof an optional mains supply input expanded its use into conventional areas of gas detectioncovering boiler plant rooms, gas meter houses, battery charger rooms and many othercommercial and light industrial applications.TECHNOLOGIES LTD Single Point Gas Sensor• Flammable, Oxygen or Toxic Gases• Compact size• Single stage alarm• Alarm relays• Alarm Sounder / LED• Digital display• Wall or panel mount• 4~20mA analogue outputSpecification Sheetref C991Technical DataPower Supply • 12 to 30 vDC - 24v nominal230/115v AC optionalSensor Type • Catalytic, Electrochemical, Infra Red, Semiconductor, Thermal conductivityMeasuring Range • Combustible gas - LEL, % vol, ppm• Toxic gas - ppm, % vol• Oxygen - % volOutput • 4~20mA Analogue option 1~5 voltsGDSISO 9001This document is not contractual and the equipment specification may be modified at any time without prior notice.
