DG-PV0E.HCL

DG/PV are designed to measure and monitor dangerous concentrations of toxic and explosive gases (and oxygen) in the air in enclosed industrial spaces. They have an interchangeable module with a measuring sensor.

They are designed to cooperate with control units (systems) of various manufacturers requiring detectors with active current output 4-20 mA or voltage output 2-10 V.

DG/PV detectors have a standard casing and cannot be used in areas classified as explosive gas, vapor or dust zones.

(Note: DG/PV detectors are not intended for use with MDP, MDA or MDD type modules).

Features

• interchangeable gas sensor;
• 2 outputs: current in standard 4-20 mA (active, i.e. emitting current) and voltage 2-10 V;
• built-in signaling of exceeding the measuring and temperature range, operating time counter, history of emergency states and signalling the end of calibration;
• thermal compensation system (can be used under changing environmental conditions);
• short detector response time;
• built-in optical signalling (2 LED lights);
• removable terminals with the possibility of embedding single and multi wire conductors (without crimping the sleeves);
• splash-proof gas sensor cover IP44 (in recommended mounting position);
• additional mechanical shield made of profiled tubes available - type AR-1d (installation in zones exposed to mechanical damage, e.g. warehouses, wholesalers, parking lots);
• possibility of being equipped with an enclosure to be placed on a ventilation duct (option DG/w);
• sensor modules for DG/PV and DG/P are interchangeable (different modules can be used for the same DG/PV body) – however, the installation conditions for individual gas must be taken into account;
• all detectors are calibrated in our own GAZEX Calibration Laboratory operating in accordance with PN-EN ISO/IEC 17025 (PCA accreditation No AP150).
