ELECTRONSYSTEM MD > Products > Density Switches > 03.3 GM + GLI / LCD / HD

The GM + GLI/LCD was developed to eliminate challenges posed by traditional pressure indicators which require a direct connection to the pressure vessel and/or a power source. It can be used with any ELECTRONSYSTEM MD pressure or density switch and mounted in an easily viewed location. Since only wires connect from the switch to the GLI, there are no extra leakage points.Vibration is also of no concern.

The device is completely resin filled and there are no mechanisms. The resin also provides protection from the elements – dust, temperature, moisture, pollution, salt mist, etc. Gas levels are shown in brief, easy to understand messages. If the pressure or density is good,“OK” is shown. A low-level alarm will indicate “LOW.” Should levels reach alarm, “VERY LOW/ NOT OK” & “DO NOT OPERATE!” are shown on the display. Information is displayed by pressing “Density Check” button on the device. Power is generated by the piezoelectric effect when the button is pressed. Should it be preferred, the device can also be powered by a Li-Ion battery.

Density Switch MV switchgear by ELECTRONSYSTEM MD


  • The electronic display is piezo powered and no battery is necessary only the energy of finger pressing is able to get the local indication
  • Switching points from gas density switch are shown by simple symbols on the LCD display of manometer
  • No necessity of gas pipe till front panel allowed to avoid the risk of leakage
  • Electrical cable connection between density switch and manometer simplify positioning on front panel passing through mechanical assemblies
  • Manometer case in stainless steel AISI 316 and resin filled to resist harsh envirorments
