Submersible tilt sensor provides high-resolution, large-angle position feedback for harsh-industrial and marine applications

Positek’s non-contacting linear, rotary, and tilt displacement sensor technology is well proven for its durability, long life, and exceptionally reliable operation in industrial, marine, and scientific applications. The leading UK sensor designer and manufacturer has now further expanded its tilt sensor range with the new S613 series that integrates the high-resolution inductive sensing technology in a fully sealed IP68-rated 10-Bar submersible housing design with a large tilt angle measurement capability.

With factory setting of the customer’s tilt travel requirement between +/- 7.5° to +/- 80°, the S613’s calibrated angle output, which may be specified in a wide choice of voltage or current output options, has an independent linearity/hysteresis specification of less than +/- 0.25°.

Particularly suited to severe industrial and marine-based applications such as crane & hoist, construction machinery or drilling platforms, although competitively priced for use on less arduous measurement tasks, the S613’s 10 g shock and 40 g vibration rating (IEC 68-2) contributes to exceptional reliability over an operating temperature range of -20°C to +85°C.

Positek’s ASIC control technology interprets the absolute position of embedded inductive coils to provide a proportional, high-bandwidth DC analogue output signal with essentially infinite resolution. In comparison to alternative LVDT/RVDT and magneto-strictive sensors, no further signal condition is required, and furthermore the space-efficient Positek sensor has a much smaller coil design, a superior stroke-to-length ratio and does not require the use of expensive magnetic materials. In this way, Positek sensors cost-effectively offers the simplicity of potentiometer-based sensors while its non-contacting LVDT principle, developed and patented by Positek, provides exceptionally long life (MTBF - 350,000 hrs at 40°C Gf).

The compact S613 features a robust and fully sealed 35 mm diameter by 44 mm long stainless-steel housing. An integral 60 mm diameter mounting flange with two wide mounting slots and a choice of input shafts facilitates straightforward mounting. A wide choice of output options include 0.5 … 4.5 V ratiometric from a 5V supply, several buffered DC voltage outputs and 2- or 3-wire, 4…20 mA current outputs from a nominal 24V DC input. Electrical connection is via a Pg7 gland and cable arrangement with customer specified length up to 50 cm.

Positek Limited is an ISO9001:2015 designer and manufacturer producing a wide range of linear, rotary and tilt position sensors for use across demanding applications in industries as diverse as oil & gas, mining, marine, agriculture, construction, off-road, motorsports, and more. Several product lines have optional ATEX, IECEx and CSA certification. A complete specification for the S613 tilt sensor is available on Positek’s website along with comprehensive information across its broad range of standard and customised products at with further information from or by calling +44(0)1242 820027.

Acquired by the Variohm Group in 2019, Positek Limited was established over 25 years ago and today operates as an ISO9001:2015 certified designer and manufacturer of linear, rotary and tilt sensors with several specialist quality standard certifications including ATEX, IECEx, and CSA for both sensors and galvanic isolation measurement amplifiers. With its own patented non-contact inductive position sensor technology the specialist enjoys a high reputation for a fast-turnaround standard range as well as customised sensors and transducers that are extensively used in intrinsically safe, hazardous, automotive, submersible and other challenging environment measurement tasks. The extremely robust and highly accurate technology allows linear position measurement up to 1500 mm or more with compact form factor angular position measurement capabilities from between 5° and 160°. Application areas include, but are not restricted to, oil & gas, mining, medical, marine, hydraulic & pneumatic cylinder position feedback, tilt sensing on construction and heavy machinery, and more.
