Rotation speed sensors
|
|
Rotation speed sensors are used to monitor, regulate and control mechanical drive systems and play a major role when it comes to protecting elements of a rotational system (e.g., in the engine, drive) from mechanical overload. Micro-Epsilon offers two sensor systems for rotation speed measurement. The capaNCDT CST6110 is a universal rotation speed sensor for counting tasks and rotation speed applications of any type. Moreover, the turboSPEED DZ140 measuring system is specifically designed for the detection of turbocharger rotation speeds. |

How do non-contact rotation speed sensors work?
Non-contact rotation speed sensors from Micro-Epsilon use two different measuring techniques for rotation speed measurement. The CST6110 rotation speed sensor is based on the capacitive measuring principle while the inductive measuring principle is used for turbocharger rotation speed measurement using the DZ140. Both measuring techniques impress with their high signal stability and interference immunity. Unlike optical measuring procedures, rotation speed sensors from Micro-Epsilon are insensitive to dust and dirt.

Universal rotation speed measurement
The capaNCDT CST6110 capacitive rotation speed sensor is designed for industrial counting tasks and rotational speed applications. Regardless of the material, the sensor detects blades, gear wheels, nubs and similar objects with the highest precision. The measuring range is 1 to 400,000 rpm. Rotation output is performed from the first detection which means no system run up is required. The robust IP67 controller and a compact sensor design make the rotation speed sensor ideal for confined installation environments.

Turbocharger speed sensors
The inductive turboSPEED DZ140 sensor system is specially designed for engine compartment and turbocharger speed measurements. The controller is integrated in an IP65-protected miniature housing intended for operating temperatures up to 115 °C. The sensor resists temperatures up to 285 °C. Therefore, the robust miniature measuring system can be easily installed in the engine compartment. The inductive DZ140 measuring principle offers excellent interference resistance for increased EMC requirements, as well as in test cells and on-road testing, while providing precise measurement results in the range of 200 rpm to 400,000 rpm.

| Non-contact, inductive displacement sensors from Micro-Epsilon operate according to the eddy current measuring principle. Unlike conventional, inductive displacement sensors, they measure on ferromagnetic and non-ferromagnetic materials providing high accuracy, frequency response and temperature stability. Due to their immunity to oil, dirt, pressure and temperature, these inductive eddy current sensors are primarily used for integration in machines and facilities. |

Performance and universality for industrial use
The new, powerful & inductive eddyNCDT 3060/3070 measuring systems are ideal for fast and precise displacement measurements. Equipped with a compact controller, a sensor and an integrated cable, these systems are factory-calibrated either for ferromagnetic or non-ferromagnetic materials. With numerous sensor models, high speed and smart signal processing, they define a new performance class in inductive displacement measurement.

New benchmark in controller technology
The industrial-grade M12 Ethernet interface enables a modern fieldbus connection. Configurable analog outputs enable to output the measured values as voltage or current. When connecting a PC via the Ethernet interface, a modern web interface can be accessed without any further installation and enables the software setting of sensor and controller.
