Abstract

A current meter having a movably mounted swivel element, in which an angle is subtended between a first leg and a second leg of the swivel element. A free end of the first leg is coupled to the handle and a free end of the second leg is coupled to the first receiving element, these being movable relative to each other, so that upon activating the handle an activating force engaging with the first leg can be generated. The activating force can be converted by the swivel element into a displacement force on the second leg, directed transversely to the activating force, so that by this displacement force the first receiving element can be moved.

Abstract

Protective device for a sensor for measuring parameters of a fluid, having a protective body (1) which is permeable to the fluid to be measured and through which the fluid to be measured reaches the sensor (3), wherein the protective body (1) has finely distributed through-openings at whose surfaces an active substance is located which renders objectionable components of the fluid to be measured at least partially harmless.

Abstract

According to the invention, particles of an aerosol are firstly charged in a unipolar manner in a diffusion charger (10). They are subsequently led through a diffusional precipitator (20) in which a part of the particles is precipitated. The diffusional precipitator current is measured and a value for the number concentration is evaluated from the current. A single diffusional precipitator may be used for this. According to preferred embodiment, a means for measuring the influence current and/or an aerosol electrometer are additionally present, by way of which one may measure a complete current. The latter additionally permits the evaluation of the average particle size. Additionally, one may determine an elementary carbon total quantity from the average particle size with the help of a measurement of the photoelectric charging carried out in parallel.

Abstract

Volatile suspended particles are eliminated from an aerosol by heating the aerosol to a temperature at which the volatile suspended particles evaporate and diluting the aerosol with a dilution gas. The sequence heating and diluting may be performed in any order. According to another aspect of the invention, dilution of the raw gas takes place such that raw gas is led to a measurement gas channel through which measurement gas flows, wherein the quantity of raw gas transferred per unit of time is dependent on the volume flow in the raw gas channel. According to a further aspect of the invention, in a condensation nucleus counter the number and intensity of scattered light pulses evaluated in order to be able to draw conclusions on the reliability of the measurement.
