GTR9

High-Precision speed measurement

The GTR9 measures rotational speed by generating a DC voltage directly proportional to the RPM value. This operating principle makes the GTR 9 well-suited for speed-controlled drives, monitoring processes and industrial systems that depend on reliable, real-time performance.

Key performance characteristics include:

• Low response time for rapid and stable measurement
• Open-circuit voltage of 20…60 mV per rpm
• High signal quality achieved through LongLife commutation
• Self-generating design requiring no auxiliary energy source

Because it operates independently of external power, the GTR9 offers high reliability even in installations with fluctuating voltage conditions.

Designed for harsh industrial environments

The GTR9 is engineered to withstand challenging industrial conditions, including vibration, shock loads and varying temperatures.

HeavyDuty mechanical construction

The proven design principle, with bearing support at both shaft ends, increases mechanical stability and extends operational lifetime, especially under continuous mechanical stress.

LongLife commutator technology

The patented commutator with a silver track provides:

• Consistently low contact resistance
• Clean and stable analogue output
• Significantly reduced brush wear

Low-maintenance design

Specially adapted brushes ensure long service intervals, making the GTR 9 ideal for continuous-run machines.

Blind hollow shaft for easy integration

The GTR9 features a blind hollow shaft (Ø16 mm), enabling quick, compact and reliable installation on motor or machine shafts.

Additional integration benefits include:

• Compact connector output
• High resistance to environmental influences
• Easy alignment and mounting
