Low-frequency Velomitor Sensor

We are a well-reputed firm that export an extensive range of Low-Frequency Velomitor Sensor in Wuxi, Jiangsu, China.

Velomitor sensor is a low-frequency version of standard
Velomitor. Its design specifically measures casing
vibration velocity on cooling tower and air-cooled
heat-exchanger fan assemblies that operate at or above 90
rpm (100 to 300 rpm typical).
