Embodiment Construction

[0059] An exemplary embodiment of a density monitor 22 is shown in the drawing. The density monitor 22 is designed for monitoring the gas density in the measurement volume. The density monitor 22 is provided with an overall housing 50 which is divided into a measurement area housing part 52 and a cable connection housing part 54 .

[0060] The measuring range housing part 52 contains a measuring device 56 with a detection device 26 for converting a variable that varies with the gas density into an electrical signal, as well as a first plug-in element 58 of a plug-in part 62 .

[0061] The cable connection housing part 54 contains a cable connection region 61 and a second plug element 60 of a plug part 62 .

[0062] One of the plug elements 58 , 60 has a plurality of pins 64 and the other of the plug elements 58 , 60 has a plurality of sockets 66 for receiving the pins 64 in a contact-contact manner. Pins 64 and sockets 66 are examples of contact interfaces for implementing e...

Abstract

In order to improve accuracy in a density monitor (22) for monitoring a gas density in a test volume, the density monitor (22) of the invention comprises a membrane (24) which is connected to the test volume in such a way as to move in the test volume when a gas density changes, and a membrane movement detection device (26), which is connected to the membrane (24), for converting a movement of the membrane into an electrical signal, the membrane movement detection device (26) being coupled to the membrane (24) by means of a transmission element (28) in order to mechanically amplify the membrane movement path.

Description

technical field [0001] The invention relates to a density monitor for monitoring gas density, which has a housing and a cable connection. Such a density monitor is known from DE 10 2010 055 249 A1. Furthermore, the invention relates to a method for assembling such a density monitor. Background technique [0002] For background on technical aspects of density monitors reference is made inter alia to JPS5578231A, US 1527597 A, US3431785 A, US 6125692 A, US 2662394 A, US 5421190 A and DE 10232823 A. [0003] A density monitor is a measuring instrument for monitoring the gas density of the gas to be monitored. As is known from DE 10 2010 055 249 A1, density monitors are used in particular for monitoring high-voltage and medium-voltage installations or high-voltage and medium-voltage installations in gas separation, such as for example high-voltage switching devices, high-pressure converters, high-pressure lines , switching instruments and transformers in the presence of gas a...
