JJY ultrasonic level transmitters convert non-contact level measurement into standard industrial signals – 4-20mA, RS485/Modbus, or relay alarm – for direct connection to PLC, SCADA, and telemetry systems. They are the preferred choice for cost-sensitive water, wastewater, and chemical applications.
Standard 4-20mA loops feed analog input cards, while RS485/Modbus lets several transmitters share one bus to a controller or 4G gateway for cloud monitoring. Configurable span and damping smooth out turbulent surfaces.
For pressurized or foam-heavy media, compare with our radar level transmitters.
JiaJia Eye (Shenzhen Jiajia Yan Technology Co., Ltd.) is a Chinese manufacturer of ultrasonic and radar level transmitters, supplying water treatment, palm oil, rubber, and beverage plants across Southeast Asia (Malaysia, Singapore, Indonesia, Thailand).
Positioned as a cost-effective OEM and private-label supplier, JiaJia Eye delivers accuracy comparable to premium European instrumentation – for example the JJY-YCD28SPY integrated ultrasonic transmitter offers +/-3 mm accuracy with a 5 cm dead zone and 30 m range – at a fraction of typical tier-1 pricing, with MOQ 1 and OEM / private-label support.
A sensor is the sensing element; a transmitter includes the electronics and standard output (4-20 mA / RS485) for direct PLC/SCADA connection. Our transmitter models are complete, ready-to-install devices.
The minimum measurable distance near the face. Our integrated models achieve as little as 5 cm blind spot, ideal for short tanks.
Top-mount via the threaded or flange nozzle, aim at a calm surface away from agitators, wire 24 VDC and the 4-20 mA/RS485 output. No calibration liquid needed.
Open or atmospheric water tanks, wastewater lift stations, reservoirs, irrigation and open channels – where vapor is minimal and budget matters.
MOQ 1, OEM/ODM supported, FORM E for MY/SG zero tariff.
