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.

  (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).
