摘要： An apparatus for determining and/or monitoring a physical or chemical process variable of a medium, having a sensor unit, which produces a measurement signal with a piece of process variable-dependent, basic information, and having an evaluation unit which, from the measurement signal of the sensor unit, determines a measured value for the process variable, and which produces an output signal with information concerning whether the measured value is greater or smaller than a limit value. A first and second modulation range are provided, and the evaluation unit modulates the output signal within the first or second modulation range with the basic information of the measurement signal, with the evaluation unit modulating the output signal within the first modulation range when the process variable is smaller than the limit value, and with the evaluation unit modulating the output signal within the second modulation range when the process variable is greater than the limit value.

摘要： An electrotechnical device is provided, having components connected by means of plug connections. The interior of the device is filled with a casting material. The device includes: a housing; arranged in the housing a first component which has at least one terminally-protruding contact pin; a second component which has a socket on which terminally-located contact plugs are provided for receiving the contact pins; and an insert in which the first component is arranged. The insert includes a secluded chamber which has an opening into which the socket of the second component is introduced. The chamber additionally includes a rear wall lying opposite the opening through which the contact pins are stuck into the contact plugs of the socket. An air-tight seal exists between the contact pins and the rear wall. The housing is filled with the casting material from an end lying opposite to the opening of the chamber.

摘要： Disclosed is a capacitance level measuring device comprised of a container whose level is to be measured and a probe inserted into and spaced from the container. The capacitance between the probe and container varies in relation to the level in the container. A capacitance measuring circuit determines the capacitance between the probe and container and thus indicates the level in the container. The integrity of the probe is verified by constructing the probe so as to include it in a series circuit, as well as the capacitance measuring circuit, and a lack of continuity in the probe is indicative of questionable probe integrity. The question as to the probe's integrity would indicate a questionable level indication from the capacitance measuring circuit. Various probe constructions are also disclosed.
