Frequently Asked Questions

Do I need different probes for different types of tachometers?

Yes, typically. Magnetic pickup tachometers require ferrous teeth or magnets on the rotating shaft. Optical tachometers need reflective tape or clear visual line of sight. Contact probes work on any surface but require direct shaft access. Indeecon supplies adapters for all three—consult your equipment specs to identify which applies.

How accurate is ±0.1% in practical terms?

At 10,000 RPM, ±0.1% means ±10 RPM deviation—imperceptible in most applications. For critical processes (e.g., motor testing, aerospace), this accuracy ensures repeatability and compliance with ISO standards.

Can I use this on moving machinery without stopping?

Yes, the optical and magnetic methods allow non-stop measurement. Contact probes require brief shaft contact, but even then, touching a rotating shaft is hazardous—always use a stroboscope or non-contact method for safety-critical equipment.

Is NABL calibration necessary for my manufacturing line?

NABL certification is required if your process is part of an ISO 17025–accredited QA system or if your OEM customer specifies it in the purchase order. For in-house performance validation, internal standards may suffice. Contact Indeecon to determine your requirements.

How does the data logging feature help?

Data logging captures 100+ RPM readings over 10–60 seconds and averages them—eliminating noise from mechanical irregularities. This averaged value is reported to your QA system, reducing false-alarm variability in SPC (Statistical Process Control) charts.
