Products âº VapoMeter - TEWL and evaporation Practical and reliable TEWL, evaporation and permeability measurements The VapoMeter is the only fully portable instrument available for the measurement of TEWL (transepidermal water loss) values and evaporation rates.
A variable reluctance sensor (VRS), also called a monopole, is used to measure position and speed of moving metal components. This sensor consists of a permanent magnet, a ferromagnetic pole piece, a magnetic pickup, and a rotating toothed wheel. As the teeth of the rotating wheel (or other target features) pass by the face of the magnet, the amount of magnetic flux passing through the magnet and consequently the coil varies. When the gear tooth is close to the sensor, the flux is at a maximum.
