Gas Detector
The gas detectors are stationary, continuously working
control devices to which sensors for the measurement
of toxic gases can be connected.
The devices stand out for their reliability and the
low
installation and maintenance work required.
They can be used in industrial and private applications.
Sensor connection
The sensors are connected via a shielded two-wire line.
The sensor enclosure accommodates the electrochemical
sensor and the sensor PCB. The sensor receives the measured
signal and the printed circuit board converts it into
a 4...20mA signal.
At the same time the PCB is supplied via the same line
with a 24 V DC auxiliary voltage. For this reason sensors
with an external power supply must not be connected.
Please make sure that every sensor is shielded when
the gas detector system is installed. Only then can
immunity from interference be guaranteed for the detector.
