Teren AVTP Probe Hot-Film Air Flow Transmitter

The Teren AVTP is a compact, probe-style air velocity transmitter designed for accurate and reliable air velocity measurement in ventilation systems and equipment. This "blind" probe (without display) is particularly well-suited for applications requiring a small footprint and integration into confined spaces, such as laminar flow measurement in small cabinets within cleanrooms and the pharmaceutical industry.

Based on the thermal anemometer principle, the AVTP utilizes an innovative and sensitive hot-film sensor. This sensor is insensitive to dust and dirt, simplifying installation and minimizing maintenance requirements. The AVTP has no moving parts, ensuring accurate, reliable, and long-term measurement stability, enhanced by good temperature compensation. Digital technology is applied to ensure accurate output, and over-voltage and reverse polarity protection provide high reliability and anti-interference capability. The innovative probe design is available in various lengths and includes scales for ease of installation and positioning.
