Carbon Dioxide Transmitter
Product Description

As a quality-oriented organization, we are focused to give our customers excellent quality Carbon Dioxide Transmitter. It is a new simple, low cost, state-ofthe-art, infrared and maintenance-free carbon dioxide transmitter for installation in the climate zone or in the ventilation duct. This measures the carbon dioxide concentration in the ambient air up to 2000 ppm and transforms the data into an analogue output. Also, before providing to our clients Carbon Dioxide Transmitter is thoroughly checked on several quality parameters by our skilled quality checkers assuring its flawlessness.

Features :

  • SenseAir's patented state-of-the-art gold-plated infrared (NDIR) waveguide technology offers reliable measurements
  • Measurement range: 0 - 2 000 ppm CO2
  • Two analogue outputs (not model -I):
  • Internal automatic self-diagnostics.
  • Maintenance-free in normal applications
  • Cost-optimized for connection to DDC:s
  • Prepared for complementary passive temperature element (model -Tr).
  • Different housing options

Applications :

  • eSENSETM is an extremely cost-optimized sensor solution for climate control of buildings and other processes.
  • By controlling the ventilation based on actual demand, it helps you decrease your energy consumption and yet have a healthy indoor climate!
  • The different housing options makes the eSENSETM available to almost any application or environment for example in greenhouses, residential and commercial buildings.
  • eSENSETM -Tr is also prepared for quick mounting of a complementary passive temperature element, which can easily be done by the customer.
  • eSENSETMII has a new housing that fits directly on top of EU and US electrical junction box standards
