Reliable Solid Level Measurement of Low-Density Foam with Jiwei Fork‑11 Tuning Fork Level Switch
1. Selected Product
2. Application Scenario & Customer Challenges
Foam materials possess extremely low density and are non-conductive, making reliable detection impossible for conventional photoelectric level switches or level sensors—often causing false alarms or failed measurements. Jiwei’s Fork‑11 tuning fork level switch, based on vibration detection and advanced piezoelectric ceramic technology, is specially designed for solid materials with extremely low density. It reliably detects down to 0.008 g/cm³, significantly enhancing measurement reliability and sensitivity.
Recently, this instrument has been successfully implemented in Guangzhou Yuhang Electric’s foam pre‑expansion machines, molding machines, and thermoforming machines, for hopper level monitoring. After commissioning, the Fork‑11 performed consistently, delivering outstanding control performance and completely resolving foam level control issues. Guangzhou Yuhang has since replaced all of its Korean Hae‑Tler vibrating rod level switches with the domestic Fork‑11, achieving local production substitution and cost optimization.
3. Why Choose the Fork‑11 Tuning Fork Level Switch?
1. Exceptional Sensitivity for Ultra-Low Density Foam
The tuning fork level switch uses a vibration-driven piezoelectric actuator. When contacting foam materials, even minute vibration amplitude changes trigger immediate measurement. The Fork‑11 surpasses photoelectric or RF-based switches in responsiveness and reliability—especially for non-conductive solids such as foam beads, resin powder, or plastic pellets.
2. Dust-Resistant, Anti-Static Design
Foam materials often generate static electricity and adhere to sensors, causing signal errors. The Fork‑11 is designed with dust-mitigation and anti-adhesion measures. Its vibration probe resists buildup, ensuring stable detection even in dusty, vibrating environments.
3. Easy Installation, No Calibration Required
The Fork‑11 supports threaded or flange installation and is plug-and-play. Customers report immediate operation post-installation, without manual threshold settings or frequent adjustments—significantly reducing on-site installation costs and setup time.
4. Long Life, Maintenance-Free Design
Jiwei’s Fork‑11 features a design without mechanical wear parts. With a rugged piezoelectric ceramic sensor and robust electronics, it qualifies as “maintenance-free.” Despite frequent start-stop cycles in foam pre‑expansion machines, the switch has operated reliably for years—a major reduction in production disruptions and downtime.
4. Customer Feedback & Highlight Case
Guangzhou Yuhang’s electrical engineering team stated:
“After installing the Fork‑11 tuning fork level switch, foam level control achieved second-level response—no shortage or false alarms. Compared to the prior high-end vibrating rod level switch, the Fork‑11 is more stable and reliable.”
After several months of operation, further praise highlighted excellent anti-static and vibration-resistance performance, and long service life. Guangzhou Yuhang subsequently replaced all their Korean Hae‑Tler vibrating rod switches with Fork‑11, achieving domestic replacement and cost optimization.
