Electrolytic Tilt Sensors - General Information

Tilt Measurement Product Overview
Company Overview
The Fredericks Company is an ISO 9001:2015 certified company
founded in 1935. Our facility is located in Huntingdon Valley,
Pennsylvania and we are a leading designer and manufacturer ofelectrolytic tilt sensors and inclinometer assemblies. Because we
design and manufacture both the core electrolytic sensing technology
and the completed inclinometer assembly at our facility, we maintainfull control over the production process of our units. This ensuresquality from unit to unit and eliminates any problems associated withparts obsolescence. Electrolytic tilt sensors manufactured at our facility
have performed reliably in the field for many years, testifying to thequality of our workmanship.
The long history of The Fredericks Company provides assurance that
we will continue to support and manufacture our products in comingyears; we also guarantee support of our products for as long as they
are being used in our customers’ products and the raw materials
remain available. Our skilled engineering team has decades ofcombined experience and can provide in depth implementation
recommendations upon request.

Inclinometers - General Information
Inclinometers are an assembly of a signal conditioner and tilt sensor.
The assembly provides an output of tilt position in one or two axes
through a variety of standard interfaces. Our inclinometers utilize
either electrolytic or MEMS technology to sense tilt angle. A regulated
power input is available as well as potting for all housed units. Potting
provides an environmental protection rating of IP67.

Electrolytic tilt sensors from The Fredericks Company provide highaccuracy angular position measurement in one or two axes. Thesesensors require signal conditioning circuitry to provide an angularoutput. The Fredericks Company offers a variety of low cost signalconditioners to run our electrolytic sensors. Customers can also designtheir own signal conditioning circuitry; TFC can provide circuit andsoftware design input and analysis upon request.

Tilt Switches - General Information

Typical Inclinometer Functional Diagram

Tilt switches provide an on/off indication of whether the unit is tilted
past a certain angle which is field programmable. The type of output
and availability of communications is dependent on the unit. All tilt
switches utilize an electrolytic tilt sensor and signal conditioner. They
are also enclosed in an ABS plastic housing with potting to provide anenvironmental protection rating of IP67. They also include a regulated
power input.
