D Series Inclinometer Rated IP67 for Harsh Environments
Description
The D Series Inclinometer can be used for any levelling application, including mobile and stationary cranes, lifting platforms, mobile weighing systems and outdoor equipment. This CE-approved tilt sensor is housed in a rugged aluminum package to protect the electronics from the elements.
Features include:
- IP67 rating for total protection against dust and immersion in up to 1 meter of water
- Robust technology that withstands shock and vibration
- .001 degree resolution
- High accuracy over wide temperature range due to internal compensation
- Meets EMC-Standard EN 61000-6-2,4
- High reliability and repeatability
- Easy to use; ready for installation via connector
- Excellent cost-performance ratio
The D Series Inclinometer is available in 3 measurement ranges: +/- 5º, +/- 15º or +/- 30º. Outputs are available as analog (0.5 to 4.5 VDC or 4-20 mA), digital (RS232) or switching output signals (.1 degree step).
Proprietary Sensing Technology
The D Series inclination sensors operate on a proprietary capacitive technology using electrolytic fluid. Platinum electrodes are deposited in pairs on the base of the sensor’s cell parallel to the sensitive axis. The chamber is partially filled with an electrolytic liquid. When an alternating voltage is passed between two electrodes, the electric current will create a dispersed field.
By tilting the sensor and thereby reducing the level of the liquid, it is possible to confine this stray field. Because of the constant, specific conductivity of the electrolytes a variance of resistance is formed in relation to the liquid level. A basic differential principle will yield an angle of inclination from the polarity signs, as demonstrated in the figures below.
