Sensor in which the sentor element is part of the sensor housing

Abstract

The invention relates to a sensor, comprising a sensor element (1) that operates without contact, an electronic component (5), and a housing (2) having an electrical / electronic connection. The sensor element (1) is part of the housing (2) and is used to close and seal the housing (2) with respect to the measurement side (3).

Description

technical field [0001] The invention relates to a sensor with a contactless operated sensor element and a housing comprising electronic components and electrical connections. Background technique [0002] The sensor discussed here is a non-contact operating sensor, and the specific principle employed is not important. In general, it can mean any non-contact operating sensor, such as pressure sensor, optical sensor, temperature sensor, capacitive or inductive sensor, etc. The sensor types discussed here are used to detect physical parameters in different applications. In many applications, the sensor is significantly affected by the environment, such as dirt, dust, water, oil or other media, which can cause incorrect measurement results or even destroy the sensor. Excessive pressure or vacuum as well as excessive temperature may also adversely affect or even destroy the sensor. Therefore, a tightly closed, often even sealed enclosure is often required in these applications...

AI Technical Summary

Problems solved by technology

However, the disadvantage of plastic enclosures is that they absorb moisture or water from the environment, especially from the air

In this way, the functionality of capacitive and eddy current sensors is compromised, since the absorbed water changes the performance of the sensor configuration and often leads to an offset of the measurement
