A1: A magnetic pickup is a non-contact speed sensor that measures rotational speed using electromagnetic induction. Inside the sensor is a magnet and coil. As gear teeth or other ferrous targets pass the sensor tip, they disturb the magnetic field, generating an AC voltage signal. The frequency of these pulses corresponds to the shaft’s RPM, which can be used for monitoring or control.

A2: Magnetic pickups are commonly found in: • Diesel and gas engines for RPM measurement • Turbines and compressors for speed monitoring • Industrial generators and pumps • Oil & gas and marine systems for overspeed protection and shutdown Integrated with Dynalco tachometers, speed switches, and digital governors for precise engine control and safety Download our magnetic pickup selection guide below:

A3: Dynalco magnetic pickups and tachometers form a complete speed monitoring system: Magnetic Pickup: Installed near a gear or flywheel, it generates an AC voltage signal as gear teeth pass its magnetic field. The frequency of this signal corresponds to engine or shaft RPM. Tachometer: Receives the signal from the magnetic pickup and converts it into a readable RPM display. It can also provide outputs for alarms, relays, or data logging. Key Benefits of Dynalco’s Pairing: Self-powered sensing: Magnetic pickups do not require external power—they create their own signals Dynalco’s SPD100, SPH-100, and MTH103E can all be powered solely from the magnetic pickup’s signal, without the need for an external power source High accuracy: Tachometers interpret the frequency precisely for real-time speed monitoring. Safety integration: Tachometers can trigger overspeed alarms or shutdowns based on pickup input. See Dynalco’s product offering below:

A4: A speed switch monitors the rotational speed of machinery and triggers alarms or shutdowns when speed exceeds or drops below safe limits. This prevents catastrophic failures in engines, pumps, and turbines.
Dynalco’s SST7000 Series offers Class I Div II approvals, with precise overspeed and underspeed protection with up to 4 programmable relay setpoints, ensuring safety and compliance in critical applications.
