    0-25 kPa, 0-50 kPa, 0-100 kPa and 0-250 kPa.

Flow Monitoring

Air Flow Paddle Switch intended to monitor air flow and non-agressive gaseous within a duct and provides a switched output on detection of either a specified air velocity or flow failure.

Air Quality (VOC) Monitoring

  • VOC = Volatile Organic Compounds.

  • Also named a Mixed Gas Sensor.

  • Used for better Indoor Climate and Energy Savings.

  • Room and Duct transmitters/transducers.

  • Output 0-10 Vdc or 4-20 mA, with or without LCD display.

Carbon Dioxide (CO2) Monitoring

  • Used for Field Controls in Green Building Applications.

  • Room and Duct transmitters/transducers.

  • Output 0-10 Vdc or 4-20 mA, with or without LCD display.

Carbon Monoxide (CO) Detection

  • CO detectors/transmitters/transducers to be used to detect toxic gas Carbon Monoxide  

  • In applications such vehicle exhaust in parking structures,
    (e.g. underground garages), engine repair shops, tunnels, equipment rooms, ventilation systems etc.

  • Electrochemical sensor element.

  • Output 4-20 mA or 2-10 Vdc.

Liquid Detection

  • Liquid Warning Detectors and
    Alarm Band for Detection of Moisture and Water

  • Early detection means Early warning.

  • Avoid leak damages.

  • Detect moisture and liquid.

  • Use VCP´s detectors and alarm band to prevent or minimize water damages.

Smoke Detection

  • Duct Smoke Detectors for Ventilation Systems.

  • The primary purpose of duct smoke detection is to prevent injury, panic, and property damage by reducing the spread (recirculation) of smoke.

  • Detection of smoke is achieved by monitoring a carefully controlled infrared beam within a perforated tube which is inserted into the ductwork.

  • This method senses smoke directly within the duct, eliminating the problems associated with conventional detectors mounted in sampling boxes.

  • IR-detection (obscuration).

  • Probe lengths 300 mm and 600 mm.
