Digital Display Platform Clearance Gauge LJ-TC-A is used to measure the vertical height from the platform edge to the top surface of the rail and the horizontal distance to the track centerline. It employs a contact-based measurement principle. In cases where the track has superelevation, it can automatically measure the superelevation and calculate the clearance dimensions.

Product Features
1. Both the horizontal ruler and the inclined ruler have display screens, eliminating the need to bend over or look down during operation;
2. Utilizes high-precision magnetic grating sensors and high-precision tilt sensors, ensuring high measurement accuracy and minimal error;
3. Automatically measures superelevation and calculates corresponding clearance dimensions when tracks have superelevation;
4. Equipped with a 5000mAh rechargeable lithium-ion battery, allowing continuous use for over 40 hours;
5. Digital display for clearer and more convenient reading;
6. The product weighs no more than 7 kg, making it easy to carry.
