SDC-Q1 - Duct Mounted

#

Duct mounted VOC transmitter

Reliable evaluation of duct air quality: The sensing element used is a MOS (metal oxide semiconductor) based gas sensor 
component. It is specifically designed for a broad detection of reducing gases such as VOCs (volatile organic compounds) 
associated with bad air quality (cigarette smoke, solvents and cleaning agents, emissions, etc.).

The microprocessor samples the air quality once per second. It calculates an averaging signal over a preset number of 
samples and generates the output signal. The analog output signal range may be customized by jumpers and can also be set by using the optional internal or external display and programming module OPC-S or OPA-S/OPU-S.

Applications

  • Demand based ventilation for homes and offices based on measurement of the VOC concentration (air quality) 
  • Recording of minimum and maximum limits for critical environments 
  • Direct control of extraction fan

Features

  • VOC measurement for air ducts
  • Minimum and maximum value memory
  • 0...10 V, 0...20 mA or 2...10 V. 4...20 mA measuring signals selectable with jumpers
  • Optional alternative signal ranges programmable
  • May be used as simple P-controller
  • Selectable averaging signal
  • Optional internal or external display (OPC-S or OPA-S/OPU-S)
  • Status LED
