80GHz FMCW radar modules · 4G solar radar transmitters · OEM/ODM from Shenzhen, China
Radar, ultrasonic and 4G wireless level instruments from one Shenzhen factory — for distributors, system integrators and brand owners who need a single, reliable source.
| Process Condition | Recommended | Why |
|---|---|---|
| Steam, condensation or foam | 80 GHz Radar | FMCW radar is not affected by vapour or foam build-up on the antenna |
| Small tank, short range (< 5 m) | Radar / Ultrasonic | 5 cm blind zone — against 20–50 cm on most industry models |
| Outdoor / no power on site | 4G Solar Radar | Solar + battery, 3 years of data traffic included, zero wiring |
| Agitators, dust or filling noise | 80 GHz Radar | Narrow 3° beam and advanced echo processing reject false returns |
| Water, wastewater, sumps | Ultrasonic | Non-contact, maintenance-free on clean liquid surfaces |
| Silo / bulk solids inventory | 80 GHz Radar | Works through dust and uneven material surfaces |
| Specification | 80 GHz Radar | Ultrasonic | 4G Wireless |
|---|---|---|---|

Practical guides on how our instruments work, how to choose and install them, and how to fix common problems — so you can move from question to solution.
Private-label manufacturing and custom engineering for distributors, system integrators and brand owners — modified antenna, 4–20 mA / HART / RS485 / 4G output or branded enclosure, with in-house calibration on every unit.
Shenzhen Jiajia Eye Technology designs and manufactures 80 GHz FMCW radar level transmitters, integrated ultrasonic level meters and 4G solar wireless level monitoring systems for industrial use. Every instrument is built in our own factory and calibrated before shipment, so distributors and OEM partners receive consistent quality rather than rebranded stock.
A 5 cm blind zone and ±2 mm accuracy — reliable in steam, condensation, foam and dust where ultrasonic sensors struggle.
Maintenance-free, non-contact design for water treatment, wastewater and sumps.
Level data to the cloud with three years of data traffic included and no monthly fees — ideal for remote or off-grid sites.
Certified to ISO 9001:2015, with Ex ia IIC T6 Ga explosion-proof approval and IP66 / 67 / 68 enclosures, our instruments are deployed in water and wastewater plants, chemical and petrochemical facilities, oil and gas, grain silos and municipal pump stations across Southeast Asia and beyond. We also supply radar ranging modules and 4G RTU gateways for integrators building their own systems.
