Acceleration sensors for derailment protection Predict and prevent damage on all types of rolling stock Critical accelerations in rail traffic can cause high damage. Sensors can detect these vibrations and initiate appropriate countermeasures in good time – for the protection of people and materials. The AccTRANS acceleration sensor measures precisely vibrations that can be caused by a pendulum movement between the gauge of the rail vehicle and the track gauge. This instability due to the track clearance is permanently detected as acceleration in a measuring range of ± 4g. The sensor is installed in the outer area of the vehicle directly on the bogie and is thus coupled with its mechanical components with sufficient strength. If the measured vibration values exceed a tolerable limit, this can cause damage to the rail vehicle. The risk of derailment of the rail vehicles arises. The sensor converts the measured values to an analog electric signal of between four and twenty milliamperes. The signal can be used to initiate preventive slowdown or temporary limitation of the train's speed. Accidents and damage caused by unstable running of the bogie are avoided successfully in this way. In accordance with DIN EN 50155, the AccTRANS is designed to operate directly in the on-board network of rail vehicles. The extremely robust housing allows the sensor to perform under the toughest conditions in the outdoor area of the train. The housing is extremely resistant to stone impact, dust and moisture and ensures high functional reliability. In the standard configuration, the sensor is available in out webshop - with a measuring range of ± 2, 4 or 5g and 24 or 110 volts supply voltage. Customized solutions, adaptation of technical parameters or retrofitting are also possible on request.
Our sensor modules, consisting of highly developed inertial and gas sensors, offer precise and reliable solutions for a wide range of measurement and analysis requirements in demanding applications.

Convenient solution for the demand of small volumes offered by Micro-Sensor. Within an average 30 years’ service life of a piece of rolling stock safety requirements for rail traffic are changing. Operators must upgrade their fleets with latest sensor technology to ensure safety standards. For this so-called retrofit, often only a small number of sensors is required. Micro-Hybrid offers a convenient solution for this case and also for prototype construction or field tests. They deliver acceleration and rotation rate sensors in small series starting, e.g. 50 pieces. Micro-Sensor also develops reliable and durable sensor solutions for OEM projects with small quantities and act as your international expert in railway applications. With more than 20 years of experience and established technologies, Micro-Sensor is a specialist for inertial sensors in the regular service and develops sensors to be used in applications in harsh environments like heat, sand and a lot more. The production processes allow manufacturing of even small series. The sensors are produced modularly and adapt all necessary steps to the individual customer requirements. This decisive advantage is enabled by the deep value chain (PCB assembly, packaging, calibration) and the broad technological expertise in the corporate group of Micro-Hybrid and Micro-Epsilon.
