LPG detectors (propane + butane)

LPG is an explosive hydrocarbon gas consisting of butane and propane. It is heavier than air and sinks to the floor in case of leakage. Therefore, the gas detector should be placed 15-25cm above the floor and within 1-2m horizontally within the range of possible gas leakage. REAL SAFE gas detectors respond audibly and visually before the leakage reaches 20% LEL. Detectors have microprocessor-based design.

Natural gas detectors (methane)

Methane is an explosive hydrocarbon gas. It is lighter than air and rises to the ceiling in case of leakage. Therefore, the gas detector should be placed 5-15cm below the ceiling and within 1-2m horizontally within the range of possible gas leakage. Real safe gas detectors respond audibly and visually before the leakage reaches 20% LEL (Lowest Explosion Level). Detectors have microprocessor-based design

 

Optional Function : Gas shut off valve/relay output for exhaust fan, Input to Central Security System

CDT series air quality transmitters are engineered for building automation systems in the HVAC/R industry. The CDT series measures carbon dioxide (CO2) utilizing the industry standard NDIR measurement principle, and temperature (T). Optional relative humidity (rH) measurement is also available in the same device. CDT series devices are available with large touchscreen display making configuration of the device quick and easy.

The CDT2000 series transmitters calibrate themselves automatically using ABC logicTM. The ABC logicTM requires that the space in which the transmitter is used needs to to be unoccupied for four hours per day so that the indoor CO2 concentration drops to the outside level. CDT2000-DC is a dual channel model with a measuring channel and a reference channel that makes a continuous comparison and the necessary adjustment accordingly. CDT2000-DC is also suitable for buildings that are continuously occupied.

CDT series devices include:
• Separate field configurable output for each measurement parameter (CO2, rH, T)
• Proportional output options including: voltage (0–10 V, 2–10 V) and current (4–20 mA)
• Offset feature enabling field calibration for each measurement parameter (CO2, rH, T)CDT2000 series device options offer:
• 2” x 3” touchscreen display
• Field configurable relay for any of the three parameters
• Modbus configuration

Applications:
  • CDT series devices are commonly used to monitor:
  • CO2 and humidity levels in offices, public spaces, meeting rooms and classrooms
  • CO2 levels of return air in ventilation systems
  • Incoming air and return air humidity levels in ventilation system
  • Humidity in various industrial applications
  • Temperatures in HVAC/R environment
  • CDT2000-DC series devices can also be used in applicationswhere there is a constant source of carbon dioxide present (forexample hospitals and greenhouses)
