Device for measuring and regulating the moisture content of a »material

The invention relates to a device for measuring and regulating the moisture content of a material «that is passed through a machine and moistened to a to achieve the selected degree of humidity «The device Is also interpreted in such a way that it is the speed controls with which the material moves through the machine is used to fit a longer or shorter tent to the Konditlonierap- ~ ready to suspend »so that according to the requirements Moistening is carried out, are provided in the device The moisture meter shown shows the moisture content of the material and sends a signal corresponding to the moisture content of the material «. A reference signal bar generates a reference voltage that is set to a selected standard humidity level «Sin Smoothness tester compares the measured humidity signal with the standard humidity signal and sends it in

In order to improve the response of the device according to the invention, a time setting device 27 is provided, which is shown in Pig. I. is shown.

the correction period 30 is energized to initiate a correction tent period. As will be explained in more detail, the encoder for the correction time 30 actually consists of two timers, namely a nose correction timer and a trooke correction timer, which are optionally actuated by an ITass or trooken converter 36. The selector yS normally selects the nose correction timer »except when a dry signal occurs in the control line 37, which is connected between the Trookenkondltionierkanal 20 and the Hass or dry selector 36. In this latter case the trooke correction timer is selected. The wet correction timer is designed for a longer period of time than the dry correction timer, so that correct drying of the material 13 is guaranteed with certainty.

The encoder for dta correction duration 30 is normally a safeguard • A sustained bias in the line 33 / between this »encoder 30 and the common connection 39 between de »resistors Rl4 and B15 is connected. These resistances are correspondingly with the Trookenkondltionierkanal 20 or connected to the Naeskonditlonlerkanal 21 «The holding pre-tension on the line is sufficient to prevent that a dry conditioning signal log channel 20 reads the transistor switch Ql, or the «a wet conditioning signal la channel 21 reads transistor switch 02. During the Tent, however, during which the giver for the correction tent duration • sets a correction period, where ea is either a Dry or a hatred correction 1st, the hold bias is removed from line 38 so that transistor switches Q1 and $ 2 respond to abnormal state signals that occur in channel 20 or * 21.

Before describing the work of each timer,

noticed that the mains connection for all timer circuits is over the outlet relay contacts 33 lead. This is a reserve set of normally open run-out relay contacts on the machine «Only when the machine is started». These contacts move and supply power from + V2 to the timers.

Similar bistable circuits are used both in the correction time delay 29 and in the encoder for the correction time 30. The encoder for the correction center frequency 31 does not have such a circle. Since the giver for the Correction time period 30 and the encoder for the correction time frequency 31 work together in tandem, if the bistable circuit is not required in the encoder for the correction time _{frequency 0} The output of this encoder 32 is at the connection point of Traneistor QSO and resistor R53 via the resistor If R50 was switched back to the sender for the correction time 30, in order to reset its bistable circuit and in doing so, restarting the encoder of the correction time period 30.

Before a more detailed explanation of these two timers, the start time delay 28 should be considered again. the. After the start delay time has expired, no further timer work takes place until one of the outputs of IC2 or IC3 becomes negative and either a dry or wet condition is displayed on the measuring instrument M1 «, as long as the measurement display remains in the normal zone, the outputs of ZC2 and IC3 remain positive. Control diodes Xl and X2 are operated in blocking and blöok the positive signals. The transistor 06 is kept on via the base drive of R25. This becomes the base of the transistor Q7 actually grounded and this remains switched off. When transistor Q7 is off, transistor Q8 is off and there this transistor acts as a series switch works to control the application of + V2 to the remaining timers, the three remaining timers are switched off.
