Leader LD-YC/YG Limit Switch Manual
The LD-YC/YG fork‑type limit switch senses liquid or solid levels by using a piezoelectric crystal to drive a vibrating fork. When the fork is immersed in liquid or covered by material, the vibration frequency changes, which the electronic circuit detects and converts into a switch signal for alarm or control.
Key features include simple installation, no calibration required, resistance to high pressure and corrosion, and suitability for medium‑viscosity liquids, corrosive liquids, and free‑flowing powders or granules. Technical specifications cover supply voltage options, temperature ranges, output types, power consumption, and installation methods for both YC and YG versions. This manual is written in Chinese.

Questions answered in Leader manuals
What is the operating principle of the LD-YC/YG limit switch?
It uses a piezoelectric crystal to drive a fork that vibrates; when the fork is immersed in liquid or covered by material, the vibration frequency changes, which the electronics detect and output a switch signal.
Does the LD-YC/YG limit switch require calibration?
No, the device does not require calibration.
What video output formats does the LT1611 support?
It provides analog RGB video (0.300–1.200 V), digital 8‑bit parallel output, and optional composite video (NTSC/PAL) via dedicated connectors.
How can the LT1611 be programmed from a PC?
Programming and control are performed through the RS‑232C interface using Windows software, allowing image and data transfer from a PC to the unit.
