RSA-MCAA & RSA-MCD Carbon Monoxide (CO) Transmitter/Controller
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 sensor life 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
- All electrical terminals are on the inside bottom, avoid any possible destroy to PCB when wiring (for RSA-MCAA)
- Digital technology applied, multiple ranges and outputs selection, over voltage and reverse polarity protection, high reliability and anti-interference capability
- Wide range of operating temperature, optional relays to actuate the alarm or control function output
LCD & function keys can set various parameters, calibrate and adjust output, so that the product can be a stand alone controller (for RSA-MCAA)
