Method of making temp. measurement probe - by setting protective tube and connections of metal socket in plastics material

摘要

The method is for making an electrical temp. measurement probe to be mounted in a connection head, esp. of type A or B of DIN 43729, is used for a probe esp. applicable to heat measurement in cases where the sensor must be proof against tampering. The measurement sensor protective tube, from whose open end the sensor connections project, is placed in the centre of a mould so that the connections from the sensor and the open end of the tube can be set in the metal housing of the connector head with plastic or alternatively can be pressed in. The measurement probe and connector head are made into a unit which cannot be taken apart and does not give access from outside. The plastics material is heat resistant.
