Catalogue

Systemic carbon oxide detector SC-CO/*2* is a device intended for continuous measurement of carbon oxide concentration in the range 0-200 ppm or 0-1000 ppm CO (or less on demand) and designed to measure gas content in the atmosphere of the mine.It is suitable for use with gas detection systems or as stand alone device monitoring parameters of underground mines and surface areas where is possibility of explosion of methane or coal dust.

Ouput signal from the detectors can be, depending on the version:

- Digital signal FSK;

- Voltage signal 0,4 ÷ 2 V or 1÷ 5 V;

- Current signal 4 ÷ 20 mA(passive);

- Frequency coded 5 ÷ 12 kHz.

Detector operates in one of following transmission configuration (depending on version):

- FSK with voltage signal;

- Frequency coded with voltage signal;

- FSK with passive current signal;

- Frequency coded with passive current signal.

SC-CO/*2* detector can operate in the stand-alone mode and then is supplied from intrinsically safe power supply unit.

The detector is also performing the function of two thresholds switch-off device, allowing control of external devices via 2 (galvanically isolated) two-state outputs. The detector is also fitted with 2 two-state inputs which can be used for confirmation of switching-off an external device.

Two alarm thresholds can be set to specific values in the range 0 ÷ 26 ppm CO.

Exceeding of given alarm threshold causes activation of alarm as a red diode (version SC-CO/*2L) or buzzer (version SC-CO/*2S) and change of given detector`s output (s). Green LED on the front informs about proper operation of the device.
