Monarch's Industrial Speed Sensors
Sensors measure process parameters such as rotational speed in industrial automation and process-control applications. These sensors are essential tools for predictive maintenance to make environments safer, more efficient, and ultimately less costly.
Monarch offers optical, infrared, magnetic, proximity, and self-powered sensors. Which one is best for your application?

To recalibrate or not? That’s a good question.
The requirement for specific recalibration is dependent upon the company/industry standard operating procedures. Many industries require current certifications to comply with set regulations for safety and quality purposes.
Monarch makes it easy to schedule your device’s recalibration.

Why measure vibration?
Vibration is considered the best operating parameter to judge dynamic conditions such as balance (overall vibration), bearing defects (enveloping) and stress applied to components. Many machinery problems show themselves as excessive vibration. Rotor imbalance, misalignment, mechanical looseness, structural resonance, soft foundation, and gear mesh defects are some of the defects that can be measured by vibration. Measuring the “overall” vibration of a machine, a rotor in relation to a machine or the structure of a machine and comparing the measurement to its normal value (norm) indicates the current health of the machine.
