Supply
DANGER
The gauge may only be connected to power sup-
plies, instruments or control devices that conform
to the requirements of a protective extra-low
voltage (PELV). The connection to the gauge has
to be fused. Grounding concept →  25.
Supply voltage
at the gauge +14 … +30 V (dc) or
±15 V (±5%)
Ripple ≤1 V

Power consumption
while being heated
at operating temperature
≤20 W
≤17 W
The gauge is protected against reverse polarity of the supply
voltage and overload.
Electrical connection 15-pin D-Sub, male
Sensor cable 15-pin plus shielding
Cable length
Supply voltage 15 V ≤ 4 m (0.14 mm²/conductor)
≤ 7 m (0.25 mm²/conductor)
Supply voltage 24 V ≤20 m (0.14 mm²/conductor)
