MEASUREMENT & MONITORING THERE NEED BE ONLY ONE! RHEINTACHO ONE SENSOR, TWO SIGNALS: ROTATIONAL SPEED SENSOR WITH AN INTEGRATED TEMPERATURE SENSOR M8-rotational speed sensors from RHEINTACHO now include two important features including not only the monitoring and measuring of rotational speed but also detect temperature additionally. This is a trend setting move of RHEINTACHO to integrate temperature recording alongside of rotational speed measurement. The sensor offers features such as temperature detection, standstill detection (0 Hz) and of course speed measurement. It is easy to set up with no alignment required. It can be used in wide temperature ranges as well as a wide range of frequencies. And all of this in just one small sensor! conditions. In hydraulic applications, the homogenizing effect is supported by hydraulic fluid. In electro-motors, the use of a temperature signal side in a speed sensor requires significantly more adaptation as the installation position has very different ambient conditions from the common installation position of the temperature sensor. The indisputable advantage of being able to call up several parameters at the same time is more present than ever. The cost advantages are complex and are not only limited to the installation costs, but also do not include requiring further sensor access gates, a very obvious advantage. For recording temperature, an NTC temperature element with the following specifications is used: ± 1.5 °C above the total operating range, NTC 4.7 kOhm, ±1 % @ R25; B25/85-value: 3830 K. The other benefits: RHEINTACHO has announced that further sensor series are now being developed in addition to the M8. Installation effort: complete elimination of one installation process. Depending on the application, the evaluation of the temperature signal has to be adapted to the differing installation Rheintacho explains: “At first glance, the idea is captivating and logical, as is every good idea. However, as usual, we can certainly say that the problem was in the detail. Especially when considering the realization of the series product, many challenges had to be overcome. But now, the products are available, and sales is developing above our expectations. We are sure further sensor series will follow.” Material costs: one complete sensor with its own electronics, own housing and connection interface are saved. Design simplification: Saving an additional sensor access including all possible side effects such as improving design freedom and reducing leakage opportunity.
