Thermo Fisher Scientific mercury-free tilt sensor
The new Ramsey mercury-free tilt sensor from Thermo Fisher Scientific has been developed to address environmental concerns and to meet health and safety regulations, regarding mercury usage.
Simple to install, the sensors are available with various probe assemblies, making them suitable for use in a wide range of production and process environments, including aggregates and coal mining.
The tilt sensor, which uses a combination of opto-electronics and solid-state circuitry within the probe, is said to prevent jitter and provide stability not found in the typical non-mercury options.
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 hangar assembly is provided with every probe to allow it to be placed in the optimum position for each individual process.
The standard Ramsey mercury-free tilt sensor uses a rugged cast ductile iron housing with a nickel chrome finish, for good abrasion resistance. It also benefits from fully potted internal electronics, which provide excellent impact resistance.
The tilt sensor’s probes, say Thermo Fisher Scientific, perform consistently and have long service life even when they are used in the harshest applications. For special installations, different probe options are available, including stainless steel and an extra-heavy, or extra-light housing.
Typical applications for the Ramsey mercury-free sensor include: high-level detection in bins and vessels; plug detector for chutes/transfer points; level control in volumetric batching; motion control for stackers; and starvation/no-flow detector for belt and vibratory feeders.
