Calorimetric flow switch designed for monitoring the flow of air and gas in ducts and pipework. The nickel-plated brass sensor operates on velocities between 1 and 20 m/s and drives a relay when the flow rises above or falls below the set point. It can be mounted with a plain shank, a threaded connection or a sliding flange.

Features

Measuring range from 1 to 20 m/s (air)
Mounting via Ø 15 mm plain shank, G ½, Rp ½, ½" NPT or DIN 43743 sliding flange
Sensor body in nickel-plated brass
Maximum pressure 8 bar
Maximum temperature 120 °C
Switching accuracy ±10 % of measured value
Relay output

Applications

Flow presence monitoring in air ducts, gas lines and ventilation or extraction systems.
