JJY (JiaJia Eye) designs and manufactures 80GHz FMCW radar level transmitters for continuous, non-contact measurement of liquids, slurries, and bulk solids in storage tanks, silos, and pressurized process vessels. Our radar transmitters achieve accuracy down to +/-1 mm and output over 4-20mA, RS485/Modbus, or 4G wireless – with no contact with the measured medium.
Every transmitter ships with 4-20mA and RS485/Modbus as standard; 4G solar radar gauges push readings to the cloud with alarm rules for remote tanks.
As a China radar level sensor manufacturer we provide OEM, ODM, and private-label services – see our About Us and Certifications.
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.
It sends 80 GHz FMCW microwave pulses; the time-of-flight or frequency shift of the echo gives the level. Microwaves pass through vapor, dust and temperature changes unaffected.
Radar wins on vapor, steam, dust, pressure/vacuum and long range; ultrasonic wins on simple open tanks at lower cost. See our radar-vs-ultrasonic guide.
Yes. Radar uses electromagnetic waves and does not need air, so it works in pressurized, vacuum and blanketed tanks where ultrasonic fails.
Up to +/-1 mm on 80 GHz FMCW; ranges beyond 30 m; narrow 3-degree beam avoids tank internals.
4-20 mA, RS485/Modbus, HART; OEM/ODM with MOQ 1 and FORM E.
