4 digital tachometer LED red light RPM meter with Hall sensor

The digital RPM counter is a professional speed measuring device for monitoring industrial equipment, machines and conveyor belts. This compact 4-digital LED device with Hall Sensor ensures accurate and reliable spin count from 10 to 9999 RPM. Digital RPM counter ideal solution for automatics, manufacturing professionals and technical professionals who need constant speed control.

Digital RPM counter - main features

• High quality Hall Sensor - The 5V sensor of the NRN type provides high sensitivity and strong reliability. Works perfectly with magnet installation and does not require frequent maintenance.
• Accurate measurement ± 0,1 per cent - the digital RPM counter gives an absolute accuracy of measurement, regardless of operating conditions or temperature variations.
• 0,56 inch Niksi LED display - high luminance red LED light provides a clear digital arrow even under difficult lighting conditions and side-by-side observations.
• Wide scope of application - Sensor works with Hall switches, metal proximity switches and infrared switches. Perfect for machines, conveyor belts and any fast rotating equipment.
• Strong and reliable construction - ABS plastic body with metal contacts for vibrations and hard work. The device maintains stable results during long-term operation.
• Simple installation - 1 Metro-connection cable and standard size of 76x39,5 mm panel aperture allow quick integration of the digital RPM gauge into the existing equipment.
• Universal power supply - DC 8-24V voltage is compatible with most industrial equipment. Easy to connect to a DC source without additional converters.

Who is it suitable for and how to use it?

The digital RPM counter is ideal for mechanics, plant operators and engineers who need precise speed monitoring. The use is simple: connect Hall Sensors to the rotating magnet object, and the digital RPM counter will immediately show the exact number of twins in the second. We recommend that the magnet be rigidly mounted to avoid its release by centrifugal force. Check the polarity of magnets before use - if there is no indication, turn the magnet on the other side.

Buyer questions

Q: Does the digital RPM counter work with any machine?
Yes, it is compatible with almost all industrial installations. It receives signals from Hall switches, metal proximity switches and infrared detectors. However, the device is only a passive scanner - you need to install the corresponding sensor to the measuring object.

Kl: How to install Hall Sensors and Magnet?
Connect Hall Sensor to the power supply (DC 8-24V) and install the magnet closer to the active area of the sensor. The magnet has to be firmly attached, as high rotational speeds can throw it away. If there is no signal, turn the magnet 180 degrees - the polarity is important.

Q: What is the warranty and delivery condition?
