MTS Sensors has unveiled its T-Series of magnetostrictive linear position sensors. These high resolution devices, which are based on the company’s Temposonics technology, are optimised for use in hazardous working environments, where they might be exposed to flames, caustic substances and potentially explosive atmospheres, such as in chemical plants or offshore oil/gas rigs.
They are the first linear positioning sensors in the industry to meet Safety Integrity Level (SIL)-2 standards. They are compliant with ATEX and IECEx Zone 0/1, Zone 1, Zone 2, Zone 21 and Zone 22 safety certifications, designated as ‘flameproof’ and ‘increased safety’.
T-Series devices are supplied in an all stainless steel design, and a corrosion-resistant stainless steel version is available. These devices can withstand shocks of up to 100g, vibrational force of up to 15g (for frequencies from 20 to 2000Hz). When operating at 60°C, their MTTF figure is 100 years and have an extensive operational temperature range covering -40 to +85°C in certain models and can cope with pressures of 350bar (5000psi) static. Protection from liquid ingress is assured thanks to these devices’ IP66, IP67, IP68, IP69K and NEMA 4X compliances. They also offer a high degree of immunity to electromagnetic radiation, in accordance with IEC/EN 61326-2-3 (Class B).
The Temposonics technology developed by MTS provides an accurate non-contact method for measuring position which is suited to use in demanding modern industrial applications. The sensors based on this technology are thus highly resilient to vibrations, shock, extreme pressures. Since these sensors are not reliant on moving parts, they have prolonged operationally lifespans, with little or no maintenance required. Furthermore, they can be mounted within even the most space constrained settings.
“The T-Series delivers a combination of performance and reliability not previously available to a broad cross section of industries sectors,” explains John Emholz, Senior Vice President and General Manager, MTS Sensors. “This series is the only one to currently offer SIL-2 capability, giving the user added value for their application, while still being cost effective.”
