STS
Sensors reliable for over 24 years
Sensor manufacturer STS from Sindelfingen received a returned combi sensor - after around 24 years in use on a ship's crane.
In autumn 2019, STS received a returned sensor: according to the company, this sensor was delivered to the former company Krupp Fördertechnik in July 1995. After around a quarter of a century of use in a heavy-duty deck crane on the high seas, Krupp Fördertechnik has now sent it back to the manufacturer due to a failure. The stainless steel housing and welded connections (IP68 protection) of the sensor obviously proved to be a worthwhile investment. According to the manufacturer, the reason for the failure was not the ingress of salt water or natural wear and tear, but a mechanical defect caused by user error.
The sensor was used to measure the hydraulic pressure and the temperature of the oil. The measurement of two process variables at a single pressure connection is considered a significant advantage of the combination sensors. Krupp Fördertechnik has been sold several times over the years and is now part of the Norwegian ship supplier TTS.
