Model Explanation

9100: EPRO Magnetic Resistor Passive Speed Sensor Series

00001: Standard Type, with 5-meter shielded cable

05: Standard Calibration, suitable for ferromagnetic tooth disks / phase-coherent slots

I. Core Parameters (Can be directly forwarded)

Measurement Principle: Passive Magnetic Resistor Induction (No power supply required, ferromagnetic teeth / slots trigger)

Speed Range: 0 - 30,000 rpm

Frequency Response: 0 - 10kHz

Output Signal: Pulse Voltage (Passive), High Level ≥ 1.8Vpp (1mm Gap, m = 2 disks)

Measurement Gap: 0.5 - 1.5mm (Recommended 1.0mm)

Probe Thread: M16×1, Stainless Steel Shell

Cable: 5m Double-layer Shielded, Oil-resistant and Wear-resistant

DC Resistance: 200 - 250Ω (25℃)

Operating Temperature: -20℃ - +85℃

Protection Level: IP67

Compatible Materials: Ferromagnetic Steel (42CrMo4, ST37), Disk with Modulus m ≥ 2

II. Wiring (2-wire system, passive)

Red wire: Signal +

Black wire: Signal -

Shield layer: Single-point grounding on the cabinet side, probe end floating

III. Installation Tips

Align with the speed measuring gear / phase coincidence groove, with an间隙 of 1.0mm ± 0.3mm

Install the probe vertically， away from the edge of the shaft (to avoid edge effect)

Keep the cable away from the power line / frequency converter， and do not share the same cable tray as the power cable

Match with the EPRO MMS6000 system (such as the MMS6120 speed module)

IV. Typical Applications

Steam turbines， compressors， fans： Speed， phase coincidence， zero-speed monitoring

Combined with the PR6424/6426 + CON021 eddy current sensors to form a complete TSI system
