Holmer Maschinenbau GmbH, a German-based agricultural company, developed the first self-propelled six-row sugar-beet harvester in 1974. Since that time, the Holmer machines have been in successful operation by customers in over 40 countries world-wide.
Sugar beet harvesters from Homer Maschinenbau require precise data collection, provided by Rheintacho speed sensors.
On its sugar beet harvesters, it requires a precise collection of actual values directly at the place of consumption (propulsion, toppers, and sugar beet transport systems). These data points are an absolute requirement for the optimum balancing of performance requirements of its high-performance harvesters for various consumers. The entire system must react precisely and quickly to the changing demands of the decentralized consumer.
For example, harvesting when the soil is looser requires less power for the harvesting module and driving through deep soil requires more propulsion power. These parameters can change during a harvesting process, making constant adjustments necessary.
Rheintacho’s FC-series rotational speed sensor
Decentralized collection of the actual, current performance needs allows a precise adjustment to the power production. Rotational speed sensors from Rheintacho are used to record one of the most important performance indicators, namely the rotational speed of the hydraulically-driven operations, in a cost-effective way and without construction restrictions.
The sensor electronics of the fitted FC-series with asymmetric, one-eyed flange is constructed as a two-channel hall differential sensor. This sensor range complies with the standard DIN/EN 13309 (construction machines, agricultural technology). It is designed to withstand especially high temperatures (up to 160 °C) and pressures thanks to its special brass alloy. The brass sensor complies with protection type IP69K thanks to its intelligently designed sealing system.
FC-series sensors withstand especially high temperatures (up to 160 °C) and pressures thanks to their special brass alloy.
The sensors of the FC-series have two frequency outputs. The extremely narrow tolerated phase shift of 20° in identifying the direction of rotation means that the sensor provides a highly precise signal and enables highly sensitive controlling.
The prompt, contact-free measurement of shaft speed in these modern mobile hydraulic control circuits from Rheintacho has become an essential part of the Holmer system to guarantee the best harvesting results with minimal influence from the soil environment.
