We provide standard and customized liquid level sensors (LLS) that measure discrete liquid levels by using ultrasonic technology. The configuration is decided by process requirements and ampoule type. With Exentec’s expertise, our level sensor can operate in high-temperature and high-density/viscosity environments to support process and material technology needs:
• Discrete level sensor probes up to 8 points
• High liquid viscosity/density capability
• High temperature capability, models up to 200° C
• TC and RTD integration capabilities
Our liquid level sensors and control boxes are popular in the semiconductor, pharmaceutical and LED industries.
