Hello, Mine Owners and Maintenance Chiefs! I am the supplier who specializes in solving problems like "no drilling depth," "jumping display readings," and "uncontrolled rotation speed." Today, I’m recommending a "small component that determines success or failure"—the Pulse Speed Sensor Dedicated to Mining Drills.
Anyone running mining drills knows that modern equipment is computer-controlled; without sensors, the machine is blind. Many cheap sensors on the market look the part but have plastic housings that shatter on impact, or are made of ordinary steel that rusts solid after a few days of underground moisture, cutting the signal entirely. Other sensors have poor sensitivity—too fast to react, too slow to register—leading to mismatches between the displayed depth and actual drilling, leaving you unaware even if you drill through. Our sensor is specifically engineered for hydraulic systems and rotating mechanisms of mining drills. It doesn't just sense; it senses accurately, transmits fast, and lasts long. Choose us to equip your drill with "hawk eyes," allowing the computer to constantly monitor the drill pipe's dynamics, giving you confidence while working.
Lightweight Aluminum Alloy Housing: Hard Yet Not Brittle:
Sensors are often installed in tight spaces; they need to be light yet strong.
Material: The housing is lightweight aluminum alloy die-cast. This material is half the weight of steel but retains full strength. Mounted on high points or moving joints, it adds no extra burden or inertial drag.
Process: The surface undergoes anodizing treatment. This acts like a "ceramic armor" for the aluminum, offering extreme hardness, wear resistance, and corrosion resistance. In underground environments full of rock powder and mud, it won't rust for years, staying bright and new.
Stainless Steel Core Probe: Precise Sensing, Ignoring Dust:
The probe is the sensor's eye; it must be sharp.
Material: The core sensing element is precision-machined stainless steel. This material is non-magnetic and resists iron filings.
Performance: Even next to gearboxes full of iron filings, it accurately captures every tooth through oil and dust. The pulse signal is clean and crisp, with no noise or missed steps. Whether measuring rotation speed or feed depth, the data matches reality perfectly.
High-Sensitivity Circuit Module: Vibration Resistant, Oil Proof, Stable Signal:
Mining vibrations are intense; ordinary circuit boards shake solder joints loose.
Encapsulation: Internal circuits use potting technology. The entire board is encased in black epoxy resin, hardening into a solid mass. No matter how much the equipment bounces, internal components won't loosen or short circuit.
Cable: The lead wire uses an oil-resistant, wear-resistant rubber sheath. It won't degrade when exposed to diesel or hydraulic oil and won't crack when dragged or crushed. The connector is a metal shielded type, locking tight to prevent signal interference.
Wide Compatibility: Install and Use Immediately:
Adaptability: Our sensor outputs a standard pulse signal. Whether for imported brands (Atlas Copco, Sandvik) or domestic brands (Shanhe, Zhigao), the control system recognizes it instantly.
Environment: Built for humid, dusty, high-vibration underground environments. Install it, power it on, and it works—no debugging required.

Lifting Equipment: Monitoring winch speed to prevent overspeed drops.
Equipment Upgrades: Adding digital depth displays to older machines to improve construction precision.
Full Range, Ready to Ship: Whether you need speed or distance measurement, we have the corresponding ready-made sensor. Just measure your mounting hole spacing and thread, and we ship immediately.
Accurate Signal, No Jumping: We guarantee our sensor is sensitive and stable. After installation, display depth and speed match reality. If there's no signal or erratic jumping, we replace it.
Value for Money: We don't sell the cheapest, because they fail. Losing signal and breaking a drill bit costs far more. We sell the most reliable. Do the math: using our sensors means zero signal loss for a year, saving enough in drill bit costs to buy a train car full of sensors.
A Quick Tip for the Mechanics:
Brothers, installing this sensor is precise and technical work.
Power Down. Before wiring, ensure the controller power is off. Hot wiring can easily fry expensive ECUs and sensors.
Set the Gap. The distance (gap) between the sensor probe and the gear tooth tip is critical. Too far won't sense; too close will grind the probe. Generally, a gap about the thickness of a business card is ideal.
Secure Firmly. Sensors are usually fixed with two screws. Tighten them securely with lock washers. Vibration is intense here; loose screws change the gap and kill the signal.
Shield Grounding. Ensure the shielded cable is grounded at a single point. Don't just wrap the shield loosely around the frame; that introduces interference. Work safely and go home in one piece!
