Speed, vibration and temperature sensors

Our robust speed, vibration and temperature sensors deliver reliable information about the condition of your system, enabling you to detect malfunctions at an early stage and avoid unplanned downtimes.

Alternatively, you can use a CombiCODER to acquire rotational speed, temperature and acceleration in a single pick-up encoder if the installation space is tight.

Our speed sensors

detect rotational and linear motion of a measuring scale that is structurally separated from the sensor like target wheels or measuring rods. Thanks to the magnetic sensing principle they are particularly suited for continuous operation in durable capital goods.

Additionally, they are also protected against extreme weather conditions, humidity, shock, and vibration due to an encapsulation process and specially developed production methods. Thus they are in compliance with DIN EN 50155 and meet the requirements of protection class up to IP 68.

Our temperature sensors

use resistance thermometers that feature an almost temperature-linear resistance curve, and output the resulting measurement data as electrical signal.

They are suitable for a measurement range from -40 °C to +250 °C. A thin stainless steel tube protects the electronics from dirt, humidity and corrosion, allowing the sensors to meet the requirements of protection class IP 68. The sensors are in compliance with fire protection standards EN 45545 and are type-tested according to EN 50155.

Our vibration sensors

are mainly used to measure the tower oscillation of wind turbines. Even though conventional, mechanical oscillation sensors provide reliable measurement in the high frequency range, they experience problems with low frequencies as produced in wind turbines.

For this reason, our tower oscillation monitors work with micro-electro-mechanical systems (MEMS), which acquire oscillations in a frequency range of 0 to 10 Hz.

They are extremely robust, dew-point resistant, and in accordance with IP 67. The sensors are not subject to ageing, and provide wear-free and maintenance-free operation.

Our odometers

is an cost-efficient solution for the mileage acquisition of goods and tank wagons.

The device is unobtrusively installed on the cover of the wheel set bearings and performs contactless measurement of the number of axle rotations.

The integrated temperature threshold monitoring serves as indicator for technical defects on the wheel set, and thus significantly increases reliability. The energy required is generated by means of induction from the rotary motion of the axle.

By eliminating temperature-sensitive batteries, in combination with a contactless measuring system, the service life of the device is virtually unlimited!
