Sensors for thermal point-level instruments detect the presence or absence of liquids and solids using thermal dispersion technology. Consisting of heated and reference sensing elements, these robust sensors accurately measure thermal conductivity changes when media contacts the probe. Manufactured from durable materials such as stainless steel or specialized alloys, they withstand aggressive chemicals, high pressures, temperatures, and abrasive conditions. These sensors reliably operate across diverse applications including chemical tanks, food processing lines, pharmaceutical reactors, wastewater treatment, and oil production facilities. Easy replacement ensures minimal downtime, maintaining system integrity and operational continuity. Precise sensor calibration and robust construction guarantee dependable performance, accurate level detection, and consistent operational safety.
