| | | Measurement Specialties Inc. offers rugged and cost-effective inclination sensors for industrial and automotive applications using multiple technologies. Inclination sensors from HL Planar, using proprietary electrolytic fluid technology, are featured below. Schaevitz® AccuStar® products, using capacitive fluid technology, are featured on page 27. The Measurement Principle HL Planar inclination sensors from Measurement Specialties operate on a proprietary 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 (see figure left). A basic differential principle will yield an angle of inclination from the polarity signs. Inclination sensors are available as modules mounted on ceramic board or as packaged inclinometers with IP ratings of 65, 66 or 67 for use in harsh conditions. | | |
