Introduction Technical Data

SCHMIDT® Flow Sensor HVAC 100

  • Cylindrical sensor head (largely independent from flow direction, easy to clean)
  • Flow and temperature signal
  • Probe length 144 mm (optional extendable)
  • Measuring ranges 0 … 2.5 m/s to 0 … 20 m/s

At many applications like ventilation, exhaust and air-conditioning systems, it is necessary to measure flow velocity, mass flow as well as the temperature of the medium to ensure an energy efficient operation of the unit.

The measuring ranges of this sensor have been tailored for the HVAC industry but also for other applications.

Easy-to-install: The HVAC 100 with its 360° measuring head does not have to be aligned to the flow direction and can be extended by additional tubes (variable immersion depth). Furthermore this sensor is maintenance-free, robust, long-term stable and easy-to-clean and therefore fulfills the main requirements for an efficient installation process.

The operating status display via LED enables safe operation at a glance and due to the fully integrated evaluation electronics in the sensor tube there are no further transmitters required.

  • Ventilation, exhaust and air-conditioning systems
  • Control of supply air and exhaust air in fume chambers
  • Filter monitoring
  • Supply and exhaust air control in digestories

SCHMIDT Technology – Simply a question of better measurement
