Programmable Alarm Features

This digital tachometer is equipped with two programmable relay alarm settings, allowing users to set upper and lower RPM thresholds for enhanced equipment safety. The alarms can trigger control outputs or alerts, helping operators respond immediately to critical speed deviations during industrial processes.

Durable and Reliable Design

Built with an ABS plastic body and certified for CE compliance, the tachometer offers robust protection against dust and splash exposure. It ensures uninterrupted performance with overload and reverse polarity safeguards. The enclosed panel-mount system is well-suited for rigorous industrial environments, ensuring long-term reliability.

Flexible Calibration Options

The unit comes factory-calibrated for assured precision, but users also have the flexibility to recalibrate the device on-site. This provides adaptability across diverse applications and installations where measurement accuracy must be maintained over time.

FAQs of Digital Tachometer with 2 alarm limits:

Q: How do I configure the two programmable alarm limits on the digital tachometer?

A: The tachometer allows you to set two independent RPM alarm thresholds via its user interface. Simply access the settings menu through the control panel, input the desired upper and lower RPM limits, and confirm the configuration. The relay outputs will activate if readings cross these preset values.

Q: What type of sensor can I use with this digital tachometer?

A: This device supports both proximity and optical sensors that operate on 12V DC. Select the sensor type according to your applications requirements and connect it through the appropriate sensor input terminals as described in the user manual.

Q: When should I recalibrate the tachometer, and how is it done?

A: Although factory-calibrated for optimal accuracy, recalibration is advised if you notice measurement drift or after extensive use. Use the calibration function in the menu, follow on-screen instructions, and apply reference RPM values to ensure precise readings.

Q: Where is the best location to mount this tachometer for industrial use?

A: The tachometer is designed for panel mounting and should be installed in a location that offers easy access to the display and controls, while ensuring protection from direct water jets or heavy dust accumulation, in accordance with its dust and splash-proof rating.

Q: What are the main benefits of using this digital tachometer for industrial RPM monitoring?

A: Key advantages include high-resolution, accurate real-time RPM readings, customizable alarms for proactive maintenance, robust protection against operational hazards, and a user-friendly LED display. It helps optimize machine performance and safety, thereby reducing downtime.

Q: How does the device handle overload or incorrect polarity during installation?

A: The tachometer incorporates built-in overload and reverse polarity protection, which safeguards both the device and connected systems during faulty wiring or voltage surges, ensuring reliability and extending product lifespan.
