E296.35.19G02 speed probe is the core monitoring component for the safe operation of steam turbines. It achieves non-contact, high-precision, and highly reliable speed measurement through magnetic resistance induction technology, providing key signals for TSI/DEH systems, ensuring stable unit speed, overspeed protection, zero speed interlocking, and load control. It is widely used in industries such as power, chemical, and metallurgical, and is an ideal choice for safety monitoring and protection of large rotating machinery

Installation key points

Installation position: turbine front bearing box, generator rotor, feed water pump turbine, aligned with the 60 tooth speed measuring gear.

Gap control: The gap between the probe and the gear is 0.5-1.5mm, accurately measured with a feeler gauge.

Wiring specification: Shielded wire with single end grounding to avoid interference; Cable conduit protection to prevent mechanical damage.

Maintenance and Care

Daily inspection: Check the appearance, wiring, and shielding layer of the probe, clean the surface oil and dust of the probe.

Regular verification: Verify once every 6-12 months to test signal amplitude, frequency accuracy, gap, and anti-interference ability.

Replacement criteria: Replace immediately in case of signal abnormalities, no output, damaged casing, seal failure, or insulation degradation.

Core product advantages

Safe and reliable: non-contact measurement, zero wear, long life, high protection, suitable for harsh working conditions.

High precision: Measurement accuracy ± 0.1%, suitable for high-precision speed monitoring of steam turbines.

Strong anti-interference: Double shielded+armored cable, stable operation in strong electromagnetic interference environment.

Good compatibility: compatible with TSI/DEH systems, 60 tooth speed measuring gears, and various speed instruments.
