Thermo Fisher Scientific introduces new Mercury-free tilt sensor

International Mining

RUGBY, UK, 20 May 2008 – Thermo Fisher Scientific Inc. (+44 (0) 1788 820300 or visit, the world leader in serving science, has announced the launch of the Thermo Scientific Ramsey Mercury-Free Tilt Sensor, incorporating advanced probes and controls designed to provide enhanced stability, sensitivity and performance. Specially developed to address environmental concerns and meet government regulations, these new units are easy to install and available with various probe assemblies which makes them ideally suited to applications utilising an array of materials in a wide range of production and process environments in the power, aggregate, paper, coal mining and processing, and mineral mining and processing industries.

The new Ramsey Mercury-Free Tilt Sensor features a simple design which is easy to understand and use. The sensor is actuated when material causes the probe to tilt at an angle of 15° or more from its vertical position. The internal sensor has a 360° design and is precisely positioned so that, regardless of the direction of tilt, its normally closed contacts will open at 15°.  A hanger assembly is provided with every probe to allow the probe to be placed in the optimum position for each individual process.

The standard Ramsey Mercury-Free Tilt Sensor probe uses a rugged cast ductile iron housing with a nickel chrome finish, for unsurpassed abrasion resistance.  In addition, the fully potted internal electronics provide excellent impact resistance.  The probes will perform consistently and supply outstanding service life in even the roughest applications.  For special installations, different probe options are also available, including stainless steel, extra heavy or extra light housings.

Typical applications include high-level detection in bins and vessels in a variety of materials, plug detector for chutes or transfer points, level control in volumetric batching, motion control for stackers and loading spouts, crash probes for tripper cars, and starvation or no-flow detector for belt and vibratory feeders.
