4.4 Analogue output
The GLACIÄR MIDI series gas detectors feature a single configurable analogue output. During normal operation, the
device’s analogue output signal is proportional to the gas concentration measured, and can be selected from the
following options:
• 1 to 5 V
• 2 to 10 V
• 0 to 10 V
• 4 to 20 mA (default)
The GLACIÄR MIDI series gas detectors use different voltage/current values to indicate different operating modes. In
normal operation, the gas concentration is indicated by the analogue output signal level. The relationship between
output signal level and gas concentration is shown below:
