The measuring device consists of several files of the Durehaesser-Sinstellgerät t with the inductive reading head ^ the display part bssw · Terstaeicer 2 _for the indicator or writer 5 and others. the control unit 4

Bie line 15 runs through it, the two measuring rollers ΐβ and t7 _r, where the roller 16 is attached to the Burehmesser setting device and the Bolle IT is attached to the free BmIe of the leaf spring 5 of the inductive measuring head. The roller 16 is expediently located under the line "because it has to take the weight of the line". Bie Bolle 16 sits on a column, the height of which can be changed measurably by a large micrometer screw with a drum. The mechanical and electrical Hall point is

given * if the Bolle of the inductive Hesskopf and the role Diameter adjustment device with no backlash and with the slightest marginal error stif lie on top of each other »So that he can with the

Leaf spring 5 is attached waä there is a little pressure, which is mainly given by the weight of the roll "on the zn · send Üeitusg on * BIe'Bolle can follow all visual fluctuations of the Burehaesser"

If, see in the case of rubber or very soft plastics, the measuring pressure still turns out to be too great ^ it can be partially canceled by an upward-acting tension spring, as shown in la BiM 2, "So that" with the lower pressure, the idler roll quietly ^ without opening dancing, rests on the fast continuous line _t is an eddy current damper consisting of the _{AlsssiniiEi-:} or Smiiferseheibe · tt ^ asi of "■ .- ■" ■. .vorgesehen magnet 12 '

In the case of very strong lines, the setting of the micrometary screw be expanded by the fact that the SFeSrolle with deat inductive leSkopf is set higher by the thickness of a suitable gauge block and. so the -Geeamtelnstellbereich is expanded.

If the lines are not running too fast Iza & u die. The measuring roller can also be replaced by a feeler pin or similar

The outer rings of ball bearings should be used as a roller, especially multi-row ball bearings are suitable for this.

The sensitivity of the arrangement is changed by changing the two reactors are brought closer to or removed from one another, so that sfcex the air gap between the leaf spring and the coils is evenly smaller or get bigger. So the same value corresponds to the diagonal voltage

When ß.eT controls are carried out, differential relays are advantageously switched in the amplifier output ». The primary coils of these relays 19 are traversed by the measuring current, the secondary coils are excited by a current coming from a constant voltage source. Both coils of each differential relay 19 are so

switches that only in the presence of a road operator, a sign of excitement occurs. Depending on the availability of the lonstamtstroaes, the response value can be continuously changed and thus an electrical definition of the flow rate "efficiency" is necessary to protect the contacts as fine differential relays, subsequent relays can be provided "old whose contacts are then 2nd B" colored Signal lamps can be switched or with which the control "can be acted upon"

Between the point of contact of the line on the machine and the place of installation of the measuring device there are usually a few meters * so only long-term changes in the diameter should be displayed as a result. trigger the control process, therefore variable acceleration stages are provided in the downstream control unit4 within wide limits.
