CMT200 Carbon Monoxide Transmitter

Description: The Model CMT200 Carbon Monoxide Transmitter is designed to provide accurate monitoring of carbon monoxide (CO) concentration in various environments, including underground parking garages, vehicle maintenance facilities, and mechanical rooms. Featuring a field-selectable current or voltage output proportional to gas concentration, this transmitter utilizes a field-replaceable electrochemical sensor for reliable performance over time. With simple field calibration procedures and durable construction, the CMT200 offers a practical solution for CO detection and monitoring.

Specifications:

  • Sensor: Field-replaceable electrochemical, 4-year typical lifespan.
  • Range: 0 to 200 ppm.
  • Output Drift: <5% per year in air.
  • Coverage Area: 5000 to 7000 sq. ft. typical.
  • Accuracy: ±2% FS at the time of calibration.
  • Temperature Limits: -4 to 122°F (-20 to 50°C).
  • Storage Temperature: For best sensor life, 32 to 68°F (0 to 20°C).
  • Humidity Limits: 15 to 90% RH constant; 0 to 99% RH intermittent.
  • Response Time: <45 seconds to 90% of final value.
  • Calibration: 15-turn span and zero adjustment potentiometers.
  • Housing: UV-resistant polycarbonate.
  • Output: Jumper selectable 4 to 20 mA (loop powered) or 2 to 10 V (load must be >50 KΩ).
  • Power Requirements: Current Output: 18 to 28 VDC; Voltage Output: 18 to 28 VDC/VAC, reverse polarity protected.
  • Electrical Connection: Removable terminal block, add two PG11 and one PG 16 knockouts for conduit fitting.
  • Weight: 0.28 lb (0.11 kg).
  • Agency Approvals: CE.

Benefits/Features:

  • Field Selectable Output: Offers flexibility with field-selectable current or voltage output proportional to CO concentration.
  • Long Lifespan: Utilizes a field-replaceable electrochemical sensor with a typical lifespan of 4 years, ensuring reliable performance.
  • Simple Calibration: Field calibration can be easily performed using calibration gas and on-board adjustment potentiometers.
  • Durable Construction: Features UV-resistant polycarbonate housing for durability and longevity in various environmental conditions.

Applications:

  • Underground Parking Garages: Monitors CO concentration to ensure safety in enclosed parking environments.
  • Vehicle Maintenance Facilities: Provides early detection of CO buildup to protect personnel and equipment.
  • Mechanical Rooms: Helps maintain safe working conditions by monitoring CO levels in mechanical equipment areas.

With its reliable performance, easy calibration, and durable construction, the Model CMT200 Carbon Monoxide Transmitter offers a practical solution for CO detection and monitoring in diverse indoor environments.
