CO233/A Carbon Monoxide Gas Sensor
Description
The CO233/A is a Carbon Monoxide (CO) gas sensor with IP65
protection that, together with a Duomo (UK) GS and BX control
units can detect the presence of Carbon Monoxide.
The sensor is fitted with an Electrochemical Cell and is managed
by a microprocessor which not only supplies an alarm signal to
the Control Unit connected to it, but also allows execution of self-
diagnosis in order to obtain the maximum detection accuracy at
any time.
This device is useful when both the maximum CO admissible
concentration threshold set to 300ppm is exceeded, and when low
CO concentrations persist in the environment for lengthy periods.
According to the principle of accumulation, could also be toxic. The
sensor has a 0-300ppm linear output conforming to the 4-20mA
standard.
