Models
RSA-TCOA Wall Mount Carbon Monoxide (CO) Transmitter
Applications & Features
-
~ It’s necessary to control the ventilation of car park and vehicle maintenance and test work shop according to many building HVAC regulations. Considering of energy efficiency, demand controlled ventilation(DCV) is recommended. It is designed for the applications which can effectively control the ventilation to safety and energy-saving operations
- Environmental friendly electrochemical sensor gives good long term accuracy, sensitivity and reliability
- Better than most other sensors 1~3 years life span, it gives more than 7~10 years life span to protect customer’s long term investment
- Better than most other sensors which may need recalibration every 6~12 months, it only need periodical recalibration as long as 3~5 years or more, maintaining 5% accuracy
- Two wire 4~20mA output, the simplest and most economical way to connect with DDC (some brands can be directly connected without additional power supply)
- Digital technology applied, over voltage and reverse polarity
protection, high reliability and anti-interference capability
- LED working status indication, with high protection housing
