Sensors For heavy-duty applications

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.

Put your trust in our wear-free, long-lasting sensors, which we are happy to adapt to your particular application. We have the appropriate certified solutions!

Contactless and wear-free speed sensors

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. Additonally 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.

You need a customised product version? By adapting the housing, or different cable and plug fabrication, we can implement almost any installation position. Depending on requirement, the sensors generate single or multi-channel square-wave signals - alternatively as voltage or current signal - ranging from 0 to 25 kHz. A standstill signal can also be implemented. On customer request we also produce, for instance, ATEX-protected product variants, special output signals for functional testing, and sensors with integrated pulse division or pulse multiplication.

Robust temperature sensors

Conventional thermometers measure the temperature by means of length or volume change of a material, and are only suitable as display instrument. 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.

Extremely resistant acceleration sensors

Our acceleration 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.

Energy self-sufficient odometers

Our odometer 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! The odometers from Lenord+Bauer are in accordance with standards EN 50155, IEC 61373 Category 3 and EN 50121-3-2. 

Ratings such as wheel set and wagon numbers are freely programmable for each counter; this ensures that the acquired data can clearly be assigned to the individual vehicles. The wheel set diameter can be individually set, allowing precise readjustment according to wear, or after wheel reprofiling. The acquired data is read via RFID and can be transmitted to an ERP or maintenance program via the USB port of the reader.
