Abstract:
A limit-level sensor for determining whether an intended level of liquid in a container is not reached or is exceeded, the sensor comprising:a resistance element for receiving an electric current, the resistance element changing its electric resistance upon an increase in temperature;a measurement unit for measuring the electric resistance;a housing having a first housing part and a second housing part;connecting wires leading to the resistance element;the connecting wires are clamped between the first and the second housing parts;wherein the resistance element is to be located entirely within a liquid of an intended level, and the electric resistance varies abruptly above a transition temperature of the resistance element, the transition temperature lying above a maximum temperature of the liquid; andwherein the first housing part has plural thin-wall transverse bars which have grooves to receive the connecting wires, and the second housing part has projections which rest against the connecting wires.
