A thermal processing and control system (300) includes a thermal processing station (312) for receiving food products (14) being carried on a conveyor system (316). A first scanning station (318) is located upstream from the thermal processing station (312) for scanning the food products being carried by the conveyor (316). An actuator (420) automatically connects temperature measuring devices (402) with selected food products (14). A diverter conveyor (324) diverts selected food products (14) from the conveyor (316) to a transverse conveyor (326) for either further processing or alternative processing, depending on how system (300) is configured. The temperature measuring devices (402) are automatically removed from the food products at station (329).
摘要:
A moving object thermometer is provided which can precisely measure the surface temperature of a moving (travelling) measurement object, particularly, a small-diameter conductive wire. A first metallic wire 1 and a second metallic wire 2 constituting a thermocouple are disposed on the outer circumferential surface 13 of the disk 11 in the rotary section 10 so as to be inclined toward the shaft center. A thermoelectric force resulting from contact of the metallic wires with a measurement object is converted into an electric signal, which is transmitted through the light emitting diode 31 and passed to the photodiode 32 provided at the stationary section 20 in a non-contact manner. Application of a high frequency current to the stationary side coil 42 provided at the stationary section 20 causes electric power to be supplied in a non-contact manner to the rotary side coil 41 provided so as to be opposed to the stationary side coil 42.

A temperature measuring method is disclosed in which, even when a sheet-like object has an uneven temperature distribution throughout itself, the sheet-like object is measured for temperature with accuracy. In this method, temperature measurement is conducted in a measuring area (S) where the sheet-like object (a) is to be measured for its physical quantity or in the vicinity of the measuring area during determination of the physical quantity by a physical quantity measuring means. One or more temperature sensors (11) are located in position proximal to each sheet-like object that streams in a predetermined direction relative to the temperature sensors (11), and air is jetted out toward the sheet-like object (a) for creating an air curtain that surrounds each temperature sensor (11) so that a gauge workspace (T) substantially confining the atmosphere therein is defined over one or both of the opposite surfaces of the sheet-like object, the measuring area (S) being within the gauge workspace (T), thereby the temperature sensors (11) detecting temperature in the measuring area (S) or in the vicinity of the measuring area within the gauge workspace (T).

In a method for wrapping an article in a sheet of thermoplastic wrapping material, the temperature of an at least partly metal belt (5) looped and induction heated to seal wrapping material (4) is detected by detecting a first signal (S1) related to the voltage (V) applied to the belt (5), and a second signal (S2) related to the current (I) circulating along the belt (5); and by calculating the electric resistance (R) of the belt (5) as a function of the first and second signal (S1, S2); the electric resistance (R) of the belt (5) being related to the temperature (T) of the belt (5).
摘要:
Apparatus for measurement of a temperature of a moving metal slab to provide a measured temperature indication corresponding to an actual temperature at a location on the surface of the slab. The apparatus comprises a first temperature measuring sensor mounted to move between a first position in which the first sensor is out of contact with a surface of the slab, and a second position in which the first sensor contacts the surface at the location, the first sensor generating an output corresponding to a detected temperature when the contact is made with the surface; a drive mechanism to move the sensor between the first and second positions of the first sensor; at least one additional temperature measuring sensor mounted adjacent to the first sensor to move between a first position in which the at least one additional sensor is out of contact with the surface of the slab, and a second position in which the at least one additional sensor contacts the surface at the location, the second sensor generating an output corresponding to a detected temperature when the contact is made with the surface; a drive mechanism to move the at least one additional sensor between the first and second positions of the at least one additional sensor; and a comparator for comparing the outputs of the temperature measuring sensors for determining whether or not the detected temperatures of the sensors at the location differ by less than a particular amount, and for providing a measured temperature indication representing the actual temperature of the surface at the location based on one or more of the outputs, only if the detected temperatures differ by less than the predetermined amount. The invention also relates to a corresponding method of measuring the surface temperature.
摘要:
Die Erfindung betrifft ein Verfahren sowie eine Anordnung zur Messung der Umgebungstemperatur in schwer zugänglichen oder gefährdeten Bereichen, insbesondere in der Nähe von Stoff-, Papier- oder dergleichen Materialbahnen oder sonstigen geförderten Werkstücken oder Werkstoffen, deren mindestens eine Eigenschaft mit einer Methodik bestimmt wird, welche mindestens die unmittelbare Umgebungstemperatur als Vergleichs- oder Referenzwert benötigt. Erfindungsgemäß wird eine an sich bekannte pyrometrische Strahlungsmeßeinrichtung eingesetzt. Ein im thermischen Gleichgewicht mit der Umgebung stehender thermischer Strahler wird in unmittelbarer der Materialbahn positioniert. Über diesen thermischen Strahler erfolgt dann eine Erfassung des Wärmestrahlungsspektrums mittels des Pyrometers und damit eine mittelbare Umgebungstemperatur-Bestimmung.
摘要:
Einrichtung zur Messung der Temperatur eines entlang einer Bewegungslinie bewegten langgestreckten Objektes (10), insbesondere eines laufenden Fadens (10), wobei das Objekt (10) eine auf einer im wesentlichen konstanten Referenztemperatur gehaltene Meßkammer (11) durchlaufen kann, in der eine Sensorfläche so angeordnet ist, daß eine Wärmeübertragung zwischen Sensorfläche und Objekt (10) stattfinden kann und wobei ein der Wärmeübertragung proportionales Ausgangssignal gebildet werden kann, wobei erfindungsgemäß mindestens zwei sich gegenüberliegende Sensorflächen (6, 7) in der Meßkammer (11) vorhanden sind, zwischen denen sich das Objekt (10) hindurchbewegt. Vorzugsweise sind die zwei Sensorflächen (6, 7) symmetrisch in Bezug auf die Bewegungslinie des Objektes (10) angeordnet und gestaltet. Dabei haben die zwei Sensorflächen (6, 7) in einer ersten Richtung senkrecht zur Bewegungslinie und senkrecht zu ihrem Abstand eine Ausdehnung haben, die größer als die insgesamt in dieser ersten Richtung zulässige Abweichung des Objektes (10) von der Bewegungslinie ist. Außerdem haben die Sensorflächen (6, 7) untereinander und in einer zweiten Richtung senkrecht zur Bewegungslinie einen Abstand, der geringfügig größer als die insgesamt in dieser zweiten Richtung zulässige Abweichung des Objektes (10) von der Bewegungslinie ist.
