Radio Energie RE.0444 R1S 0.06 CA DC Tachogenerator for Speed Measurement

The Radio Energie RE.0444 R1S 0.06 CA is a precision DC tachogenerator designed for converting rotational shaft speed into a proportional DC voltage. Derived from the RE.0444 N model, it is widely used for speed feedback in closed-loop control systems, elevators, industrial machinery, and process monitoring. The RE.0444 series offers high linearity and low ripple, enabling accurate speed measurement in demanding applications.

Electrical Specifications

The RE.0444 R1S 0.06 CA produces an output voltage of 60V per 1000 RPM, providing strong signal amplitude even at low speeds. The calibration tolerance is ±5%. Power consumption is 0.6W at speeds ≥5000 RPM. The armature-circuit time constant is<4 µs, ensuring fast response to speed changes. The tachogenerator does not require an external power supply, generating a DC voltage directly from shaft rotation. This self-generating principle ensures reliability and minimal signal propagation delay.

Mechanical Construction

The housing is made of aluminum, offering good mechanical strength and heat dissipation. The shaft type can be plain or keyed depending on system requirements. The protection class is IP55, providing protection against dust ingress and low-pressure water jets from any direction. Mounting is flange-mounted for secure installation directly onto motor shafts or equipment drive ends. The unit is designed to withstand industrial vibration and environmental exposure.

Compatibility and Interchangeability

The RE.0444 R is fully compatible with the Baumer Hubner TDP02LT in terms of form and function. If replacement of a TDP02LT tachogenerator is required, the RE0444 R serves as a suitable alternative without significant modifications to the existing setup. This interchangeability simplifies maintenance and parts replacement for legacy systems.

Regulatory Approvals

The RE.0444 R1S 0.06 CA carries CE and CSA approvals, confirming compliance with European and North American standards for electrical safety and electromagnetic compatibility. The unit can be used in machine control systems requiring certified speed feedback devices.

Applications

The tachogenerator is used for precise speed measurement in closed-loop speed control systems for DC motors and drives, monitoring elevator and lift motor speed for passenger comfort and safety, providing feedback in industrial machinery such as extruders, winders, and printing presses, process monitoring where real-time speed data is essential, integration into control loops for high-precision motor regulation, and replacements for Baumer Hubner TDP02LT units in legacy installations.

Conclusion

The Radio Energie RE.0444 R1S 0.06 CA tachogenerator provides 60V per 1000 RPM DC output in a rugged IP55 aluminum housing. Its fast time constant (<4 µs), flange-mount design, and compatibility with TDP02LT make it suitable for speed feedback in industrial motor control and elevator systems.
