OverviewThe YUNYI XY‑CT Series is a miniature ultrasonic level transmitter engineered for installations with very limited space that still require high measurement precision. It offers an ultra‑small blind zone (as low as <0.06 m on select ranges), high resolution accuracy (±1 mm to ±1.5 mm depending on range) and compact housing options in 304 stainless steel or copper‑plated finish. The transmitter uses an industrial‑grade microcontroller with digital temperature compensation, ultra‑wide voltage input regulation and specialised integrated circuits for stable long‑term operation.
Key Features- Ultra‑small blind zone – down to <0.06 m for proximity mounting to the measured surface.
- High precision – accuracy from ±1 mm to ±1.5 mm depending on selected range.
- Compact rugged housing – Φ28 mm × 100 mm (M30×1.5 thread) suitable for confined installations; materials: 304 stainless steel or copper‑plated.
- Automatic temperature compensation – built‑in sensor provides real‑time compensation for stable readings.
- Strong anti‑interference design – suitable for electrically noisy industrial environments.
- Flexible outputs – analog (0‑20mA, 4‑20mA, 0‑5V, 0‑10V), digital (RS485 with Modbus) or switch output; configurable upper/lower setpoints via host software.
- Non‑contact measurement – avoids fouling, clogging, leakage and corrosion, reducing maintenance.
- Intrinsic safety – Ex ia IIB T4 Gb explosion protection certification.
- Wide input voltage – DC 12‑24V with ultra‑low power consumption <1.5W.
- Easy installation – M30×1.5 thread; supplied with 1.5 m cable.
