摘要:
A measuring sensor has a hollow body through which a fluid is able to flow. Two sections of a wall of the hollow body form electrodes for a capacitive and/or a resistive measurement and the electrodes are made of a conductive plastic. The measuring sensor may be used in a fuel feed line. A method for manufacturing is also described.
摘要:
The capacitive measuring probe has the following: two electrodes, a plastic casing which encapsulates the two electrodes, the plastic casing having at least one section made of a conductive plastic, which is electrically connected to one of the two electrodes.

A fluid sensor includes a metal housing body, which has a box and a flanged ring circumferentially surrounding the box. A housing jacket is formed from plastic material and disposed on an exterior side of the housing body. A sealing ring, which is situated circumferentially on top of the flanged ring, subdivides the housing jacket into two sections that are insulated from each other.

The invention provides a fluid sensor device (1; 1′; 1′; 1″) for detecting a dielectricity constant of a fluid (30) present in a fluid line (20), comprising a housing (5; 5′; 5′; 5″); a plate capacitor device provided on the inside of the housing (5; 5′; 5′; 5″), the plate capacitor device comprising a first and a second capacitor plate (8a, 8b; 8a′, 8b′; 8a′, 8b′; 8a″, 8b″); wherein the housing (5; 5′; 5′; 5″) on the surface thereof has an arched attachment region for attaching the fluid line (20); and wherein the first and second capacitor plates (8a, 8b; 8a′, 8b′; 8a′, 8b′; 8a″, 8b″) are disposed next to the attachment region such that a fluid (30) present in the fluid line (20) attached in the attachment region is provided at least partially between the first and second capacitor plates (8a, 8b; 8a′, 8b′; 8a′, 8b′; 8a″, 8b″).
摘要:
Disclosed is a gas measuring device which comprises compensation of disturbances and offers high accuracy of measurement immediately after being activated. Said gas measuring device is provided with a gas sensor (1) for generating a measuring signal (S1) that depends on the gas concentration and can have a spurious component while a high-pass filter (13) having an adjustable limiting frequency is mounted downstream of said gas sensor (1). The limiting frequency can be predefined according to the spurious component by means of a selection unit.
