Construction for fastening and contacting resistor elements for a hot film anemometer and sensor arrangement using such construction

摘要

In order to obtain a rapid response of resistor elements having a hot film in a sensor carrier of a hot film anemometer, the resistor elements are inserted into a drawer-like recess at one end of the sensor carrier. The resistor elements rest with one end on a three point contact and are held fast on the three point contact through tension by means of contact springs in the connection area of contact clamps. Heat transfer which is detrimental to exact measurements can be avoided by means of the three point contact.
