G5+ Gauge – Removable inclinometer

Technical specifications

Advantages of the G5+ removable inclinometer

The G5+ gauge is a removable inclinometer designed to measure changes in an inclination or a tilt. The principle is the same as the G5 gauge, but this removable version is positioned in specific baseplates to take the reading; the gauge is then removed and stored in its carrying case. Repeatable readings are ensured by centring on machined parts.

This approach has several advantages:

• Durable and hard-to-vandalise solution: only the aluminium G5+ baseplate stays on the surface after the reading, so there is no risk of damage to the measuring instrument and no protection needs to be added.
• Flexible positioning: depending on requirements, the G5+ gauge can be placed flat or perpendicular on the baseplate to take the reading.
• Cost-effective: when a large number of points need to be monitored, buying additional G5+ baseplates is more economical than buying several G5 gauges.

Fixing the G5+ baseplate and positioning the G5+ inclinometer

The G5+ gauge is held magnetically in a baseplate with locating pins. A G5+ baseplate must therefore always be fixed, using the screws supplied, before the G5+ gauge can be used.

The G5+ gauge is simply positioned by magnetic attraction, using the positioning guides on the body of the gauge. 3 positions are possible:

Reading the G5+ inclinometer

The reading principle is exactly the same as for the G5 gauge. Stand directly in front of the needle, with your eyes level with the dial, to avoid any parallax error. To make sure you are exactly in front of it, you should not be able to see the sides of the needle.

Read according to the vernier principle:

• The lower scale is graduated in mm from 0 to 70 mm: this is the measuring scale.
• The upper scale, on the pendulum needle with the T, is movable: this is the vernier, reading to 0.1 mm (10 vernier divisions correspond to 9 mm on the measuring scale)

1. Reading the millimetres

   The T mark of the vernier lies between two graduations of the measuring scale. Example: between 28 and 29. The number of mm corresponds to the graduation to the left of the vernier T mark: 28 mm in the example.

2. Reading the decimal

   Look for the vernier line that coincides with a line on the measuring scale. In the example, vernier graduation 7 coincides with graduation 35 on the measuring scale. In other words, the decimal reading is 0.7 mm.

3. The reading in the example photo is therefore 28.7 mm

The difference between two consecutive readings, MULTIPLIED by 5, gives the change in mm per metre of height.

So, change in inclination or tilt at the top = Absolute value (M2 – M1) x 5 x H
