Threshold gas detectors DG/EF

New

The DG/EF two-threshold, economical detectors are designed to detect the presence of dangerous gas concentrations in the air in industrial, enclosed spaces. They have a replaceable sensor module with two standard alarm thresholds (thresholds set at the production stage, built-in third threshold signaled only optically).

DG/EF detectors are designed to work with:

• threshold control units of type MD-1.A/T, MD-1, MD-2, MD-4;
• measuring and threshold control units of type MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16.

DG/EF are detectors of standard design and cannot be used in areas classified as hazardous due to the presence of gases, vapors, or dust.

Features

• replaceable gas sensor: semiconductor, optical (Infra-Red);
• two standard alarm thresholds set during production (the third threshold is usually the upper measurement range of the gas sensor, signaled only visually), 4-wire interface;
• built-in event history (analysis available from the manufacturer), indication of the recommended calibration period expiry; built-in test procedure for recognizing output cables (after power-up);
• thermal compensation system (can be used in variable environmental conditions);
• easy gas penetration through the sensor cover = relatively short detector response time;
• built-in optical signaling (multi-color LED);
• removable terminals with the possibility of mounting single- and multi-wire cores (cable – without crimping sleeves);
• splash-proof IP44 gas sensor cover (in the recommended mounting position);
• can be equipped with a mechanical cover made of AR-1 profiled pipes (installation in areas exposed to mechanical damage, e.g., warehouses, wholesale stores, parking lots);
• all detectors are calibrated in GAZEX Calibration Laboratory operating in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation no. AP150).
