Abstract
Improvements in the construction of electronic relays for liquid level detection, characterized by the fact that the electronic relays, provided with the corresponding testing device and with characteristics appropriate to the type of alarm provided, receive the signal from an element of detection constituted by a probe mounted on the container of the liquid whose level it is desired to control, the relay acting the signaling element, integrated in an electronic circuit whose number of transistors will be adapted to the resistivity of the mentioned liquid, being the probe formed by one or two souls of stainless steel or other suitable conductive material, which constitute the probe electrodes, connected to the circuit or circuits by means of conventional tabs and connectors through cables, the same being supported by a threaded head, preferably obtained on the basis of of a polymer thermally est abilizado, foreseeing the incorporation of the circuit or electronic circuits in corresponding boxes of switches, as well as in any type of metal canister, integrating in it the acoustic alarm circuit, while the optical signal circuits by incandescent lamp eventually carry the lamp built-in and take advantage of the switch button to check the good condition of it.
