4100-DP GMA 4100-DP Dew Point Monitor by GfG

The GMA 4100-DP continuously provides information on the measured dew point level, exceeded alarm thresholds and its operational status. As soon as the dew point exceeds one of the three pre-set levels, the GMA 4100-DP gives a warning by means of the LED display, the console mounted horn/strobe, and controls the relevant alarm relays. In addition to this, the GMA 4100-DP provides the measurement value as an analog output signal for further evaluation. The GMA 4100-DP is easy to operate and maintenance-free. The dew point sensor is self calibrating and lasts for years. Should unexpected failures or system faults occur, the comprehensive failure recognition allows a quick and specific service.

Alarm points

Each alarm can be adjusted separately. Relay chatter is eliminated with the adjustable alarm delay. The alarm point values can be freely adjusted using the keypads on the controller.

Alarm relays

The controller provides four voltage-free relays for the three alarms and one fault warning. The relays may be used to control additional alarm devices like lights or horns.


  • Dew point value readings on a 3-digit display
  • Menu display
  • 3 adjustable alarm thresholds (alarms must be +1 or higher)
  • Peak value memory
  • Adjustable relay functions: NC or NO contact
