Novotechnik U.S. released its TM1 Series of magnetostrictive linear hydraulic and pneumatic position sensors. The sensor features a magnetic ring-shaped marker that affixes to an application’s moving cylinder and moves up and down the TM1 rod without contact. The series’ stroke lengths are from 50 to 2,000mm in 25mm steps. Operating pressure is up to 5,076 psi (350 bar) with peaks to 6,526 psi (450 bar). Both plug-in and screw type flange models are available. Other key specifications include absolute linearity of ≤ 0.04% F.S. (min. 0.3mm) and repeatability of ≤ ±0.1 mm. Output options include 4 to 20mA current as well as voltage output of 0.25 to 4.75V, 0.5 to 4.5V or 0.1 to 10V. Ingress protection is to IP 69K, shock and vibration 100g and 20g respectively. Operating temperature range is to -40 to +105°C.
