📌 Purpose:

The THM-11 tachometer is designed for use in automation and process control systems where it is necessary to:

  • ⚙️ Measure the rotational speed of shafts in rotating mechanisms (motors, fans, pumps, drums, etc.).
  • 🚚 Monitor the linear speed of moving objects (conveyors, belt conveyors, roller tracks).
  • ⏱ Determine the operating time of units, equipment, and mechanisms in hours, minutes, or days.

⚙️ Functional Capabilities:

  • 📏 Measurement of rotational speed with the ability to display in:
    • 🔄 rev/s – revolutions per second;
    • 🔄 rev/min – revolutions per minute;
    • 🔄 rev/h – revolutions per hour;
    • 📐 User-defined units – custom units via scaling factor.
  • 📊 Frequency measurement range — from 0.5 Hz to 25 kHz.
  • ⏳ Operating time measurement — from 1 s to 9999 days.
  • 🔌 Supports connection of various primary sensors:
    • 🔵 Open-collector transistor sensors NPN and PNP;
    • ⚪ Reed switches.
  • ⚡ Output elements:
    • 🛎 Relay output for signaling or controlling actuators;
    • 📤 Analog output (0…10 V or 4…20 mA) for transmitting measured values to external systems.
  • 💾 Retention of settings and results in built-in non-volatile memory when power is off.

🌐 Interfaces & Communication:

  • 🔗 RS-485 with Modbus RTU protocol — for integration into industrial control (SCADA, PLC) systems.
  • 💻 USB port — for PC connection, parameter setup, and calibration.

💡 Additional Features:

  • 🎯 Ability to set threshold values for relay output (SET POINT) with hysteresis.
  • ▶️⏹ Operation in continuous measurement mode or start/stop control via discrete input.
  • 🛡 Galvanic isolation of inputs, outputs, and interfaces from the power circuit.
  • ⚡ Sensor power supply from a built-in +24 V source.
