1 Technical Data

1.1 Electrical Data

1) T = +25°C, 90% total measurement range

2) e.g. temperature drift AGS005 (T= 0°C up to +55°C) = 55K * 0,001°/K = 0,055°

3) Supply voltage is applied.

4) Inclinometers should be connected only to subsequent electronics whose power supplies comply with EN 50178 (protective low
voltage)
