Measurement & threshold gas detectors DG/P

Detectors DG/P are used for continuous monitoring of premises for combustible and toxic gases. The detector performs cyclic measurement of gas concentration in the air and transmits the measured value in 4-20 mA standard (passive output).

DG/P detectors are designed to work with:

• measuring and threshold control units of type MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16;
• addressable control units of type MDD-1, MDD-1/T, MDD-1x/T;
• with any other control panels accepting the 4-20 mA input line standard (with current emission).

For use with control units from other manufacturers, GAZEX recommends to use detectors type DG/PV with dual outputs (active 4-20 mA and 2-10 V).

Features

• 4-20mA standard analog output (passive);
• easily exchangeable sensor unit and easy maintenance;
• easy change of the detected gas or calibration of the detector;
• built-in temperature compensation;
• infra-red sensor for combustible gases or electrochemical sensor for toxic gases or oxygen;
• sensor unit with “zero” and “span” regulation (calibration outside the detector);
• low-cost operation;
• all detectors are calibrated in GAZEX Calibration Laboratory operating in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation no. AP150).
