Description

The ProSens line model QF-622 is dedicated to HVAC systems, but not only. The thermal air velocity transmitter used in this model, allows measuring flow of air and other compatible, not combustible gasses. Thanks to the wide range of measuring probes, ProSens transmitter can be used in: air-condition systems, flow measurements, fans monitoring, cooling systems, or many similar applications.

Model QF-622 has air flow connector or cable probe, Ø12 mm, L=300 mm, stainless steel 316L probe and filter cap.

A large built-in display and output signals mean that the ProSens line units find applications in control systems. There are many industrial applications, where ProSens can act as stand-alone controller. It can also cooperate with master devices via Modbus protocol, being part of big network, which makes it perfect instrument for distributed monitoring system.
