Beschreibung des "elektronischen Psychrometers"Description of the "electronic psychrometer"
Das im folgenden beschriebene Gerät, elektronisches Psychrometer, dient zur Bestimmung der Luftfeuchte und damit zur
Berechnung des Breehungskoeffizienten der luft; die Gesamtkonzeption
ist zu schützen.
Es besteht aus 2 TeilenThe device described below, the electronic psychrometer, is used to determine the air humidity and thus to calculate the expansion coefficient of the air; the overall concept is to be protected.
It consists of 2 parts
a) Meßteil AnI.1a) Measuring part AnI.1
b) Bedienteil "J .-.--·'·"b) Control unit "J.-.-- · '·"
Durch die räumliche Trennung soll der Einfluß des Beobachters ausgeschaltet werden.The spatial separation is intended to eliminate the observer's influence.
Eigentliche Meßelemente sind 2 Heißleiter der Firma VAIVO,Actual measuring elements are 2 thermistors from VAIVO,
Hamburg, Typ E 2o5 CE/ P JI(Sl 4 K 7 S, die in eine Wheatstone-Hamburg, type E 2o5 CE / P JI (Sl 4 K 7 S, which is in a Wheatstone
Brücke engebaut "sifad ( AKI. 4 ) .Bridge built "sifad (AKI. 4).
Die Heißleiter Bind zwischen die beiden Punkte A und B (AnI.4) eingeschaltet; der eine Heißleiter wird durch einen Docht, derThe thermistor bind between the two points A and B (AnI.4) switched on; one thermistor is through a wick that
in einem Wass.ervorratsgefäß endet, dauernd befeuchtet(AnI.2).ends in a water storage vessel, permanently moistened (AnI.2).
Dadurch wird es möglich, an einem Strommeßgerät von ca. o,3This makes it possible to use an ammeter of approx. 0.3
bis o,6 mA Meßbereich einen Temperaturbereich von etwa 9o°Ö zu überstreichen.Up to 0.6 mA measuring range, a temperature range of about 9o ° Ö to paint over.
Das gesamte Gerät besteht fast ausschließlich aus PlastikteilenThe entire device consists almost entirely of plastic parts
(PVC); das hat wesentliche Vorteile: geringes Gewicht, Schutz(PVC); this has significant advantages: low weight, protection
gegen Wärmestrahlung, Korrosionsbeständigkeit.against thermal radiation, corrosion resistance.
Die für die Messung notwendige Ventilation wird durch einenThe ventilation required for the measurement is provided by a
Kleinelektromotor mit aufgesetzter dreiflügliger luftschraubeSmall electric motor with attached three-bladed propeller
( ebenfalls Kunststoff) besorgt. Spannung 3,6V, Ventilation(also plastic) worried. Voltage 3.6V, ventilation
min 3 m/sec.Der Motor sitzt im oberen Teil des Meßteils und ist so eingebaut, daß er die Luft von unten nach oben saugt undmin 3 m / sec. The motor sits in the upper part of the measuring part and is installed in such a way that it sucks the air from bottom to top and
sich damit selbst kühlt.cools itself with it.
Der Meßteil läßt sich in der Mitte durch eine einfache DrehungThe measuring part can be easily turned in the middle
in 2 Teile zerlegen. Er ist wettergeschützt.disassemble into 2 parts. It is protected from the weather.
Die Schaltung bzw. der Bedienteil sind so aufgebaut, daß mittelsThe circuit and the control panel are constructed so that by means of
des Schalters "EICHEH" vor oder zwischen den Messungen mit einemof the "EICHEH" switch before or between measurements with a
Regelwiderstand ( Trimmer in AnI.3) auf einen Eichpunkt geeichtControl resistor (trimmer in AnI.3) calibrated to a calibration point
wird.Durch einen weiteren Segelwiderstand (C in AnI.4) kann der Gesamttemperaturbereich verschoben werden.With a further sail resistance (C in AnI.4) the Total temperature range can be shifted.
Jbei Schalterstellung "MESSEN"" wird durch Knopfdruck jeweils die der feuchten bzw. trockenen Temperatur entsprechendeWhen the switch is in the "MEASURE" position, pressing a button the one corresponding to the wet or dry temperature
Stromstärke angezeigt (AnI.3). Der Meßstromkreis wird durch eine 4,5 V Trockenbatterie gespeist.Amperage displayed (AnI.3). The measuring circuit is through fed by a 4.5 V dry battery.
Temperaturwerte werden entweder an einer Eichtabelle oder aus einer Temperaturgleichung entnommen.Temperature values are either taken from a calibration table or from taken from a temperature equation.
Die Genauigkeit beträgt bei o,6 mA Meßbereich The accuracy is with a measuring range of 0.6 mA
und ca. 9o mmm Skalenlänge ±o,2°C.and approx. 9o mmm scale length ± 0.2 ° C.
