GDC - ELECTRONSYSTEM MD

Electronsystem MD products are designed not only for traditional SF₆, but also for alternative insulating gases such as Green Gas and Dry Air.

Visual indication of density level.
Temperature compensated pressure gauge.
Up to 4 switching levels and independent changeovercontacts with decreasing or increasing thresholds(up to 3 on GDH).
Based on reference chamber principle for ultimatestability and repeatability.
Follows SF6 Isochor (temperature vs. pressure curve), even in liquid phase, meaning no false alarms in low temperatures.
Pressure and reference chamber bellows made from stainless steel.
High resolution- can detect even the smallest leaks.
Can be configured for use on mixed gas switchgear (SF6 /N2; SF6 /CF4).
Use of micro-switches to eliminate contact bouncing.
Shock proof up to 50G on 3 axes.
IP65- Designed for outdoor installation
Maintenance free.
SF6 sample and reference chamber insulated fromoutside covering.
Switching tolerance < 0.2 bar.

Able to calibrate a “Self-diagnosis” contact for monitoring the reference chamber and alert user should leakage occur. The device would still function normally if there was a leak in the measuring bellow.
Available with digital or analogue output signal for continuous monitoring (GDHC); typically used with remote monitoring devices which totalize fugitive SF6 emissions and/or provide SF6 refill maintenance forecasting.
Customized gas connections.
Low temperature version available (-60°C).
