Sweep Frequency Level Sensor for Jam Production | Food-Grade Detection
01.Jam Production Pain Points | Why Ordinary Level Sensors Fail
Jam production features highly viscous raw materials mixed with dense fruit pulp, which easily adheres to equipment surfaces. During stirring, boiling, and automated filling processes, materials frequently produce foam, steam, and turbulent liquid fluctuations. Conventional standard level sensors are unable to distinguish between residue buildup, foam interference, and real liquid level changes, resulting in frequent false alarms, signal instability, and inaccurate level feedback. These defects easily cause production interruptions, material overflow, equipment idling, and unstable batch quality, becoming a key bottleneck restricting automated and continuous jam production.
02.Working Principle | Intelligent RF Sweep Frequency Detection Technology
