(54) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ ТЕМПЕРАТУРЫ(54) DEVICE FOR TEMPERATURE MEASUREMENT

Изобретение относитс  к измерительной технике и предназначено дл  измерени  температур термопарами, в комплект с многоканальным измерительным прибором . Известно устройство дл  измерени  температур содержащее термопары, компенсационные хровода и многоканальный измерительный прибор при этом, все термопары псдключены к компенсационным лфоводам одной из них l. Недостатком устройство  вл етс  невозможность измерени  разности температур . Наиболее близким к предлагаемому  вл етс  устройство дл  измерени  темп ратуры, содержащее термопары с компенсационными проводами, к которым подсоединены одноименные электроды дополнительной термопары, при этом компе сационные провода соединены перемычками с соответствующими клеммами измерительного пркбора 2. Недостатком данного устройства  вл етс  невозможность одновременного измерени  разности температуры и абсолютных значений в точках размещени  основных и дополнительной термопар. Цель изобретени  - расширение функциональных возможностей устройства путем обеспечени  одновременного измерени  температур и их разности. Указанна  цель достигаетс  тем, что электроды дополнительной термопары присоединены к спа м двух других термопар. На чертеже показа1 а схема гфедлагаемого устройства дл  измерени  температуры . Устройство содержит термопары 1-3, из которых, термопара 1 дополнительна , компенсационные провода 4-7, перемычки между клеммами 8-19 измерительного щзибора 20. Термоэлектроды дополнительной термопары 1 присоединены к спа м термопар 2 и 3, Щ)И этом каждый термоэлектрод термопары 1 образует термопару:The invention relates to a measurement technique and is intended for measuring temperatures by thermocouples, in a set with a multichannel measuring instrument. A device for measuring temperatures containing thermocouples, compensating circuits and a multichannel measuring device is known; in this case, all thermocouples are connected to compensatory thermometers of one of them, l. A disadvantage of the device is the impossibility of measuring the temperature difference. The closest to the present invention is a device for measuring the temperature of the circuit containing thermocouples with compensation wires to which the electrodes of the additional thermocouple of the same name are connected, while the composite wires are connected with jumpers to the corresponding terminals of the measuring unit 2. The disadvantage of this device is the impossibility of simultaneously measuring the temperature difference and absolute values at the locations of the primary and secondary thermocouples. The purpose of the invention is to enhance the functionality of the device by providing simultaneous measurements of temperatures and their difference. This goal is achieved by the fact that the electrodes of the additional thermocouple are connected to the spans of the other two thermocouples. The drawing shows a diagram of a gated device for measuring temperature. The device contains thermocouples 1-3, of which, thermocouple 1 is additional, compensation wires 4-7, jumpers between terminals 8-19 of the measuring cable 20. Thermoelectrodes of additional thermocouple 1 are connected to thermometers of thermocouples 2 and 3, S) and this is each thermocouple of thermocouple 1 forms a thermocouple:

с разноименным электродом термопар 2 и 3.with opposite electrode thermocouples 2 and 3.

Устройство работает следующим образом ..The device works as follows.

При изменении термо-ЭДС на клеммах 9 и 15 ощзедел ют температуру Tj,, измер емую тер.мопарой 1, На клеммах 8 и 12 определ ют температуру То, измер емую термопарой 2, на клеммах 16 и , 18 температуру Tj, измер емую термопарой 3, на клеммах Ю и 17 определ ют разность температур Т, T-j между термопара (Яи 1 и 3; на клеммах 11 и 14 разность температур между термопарами 1 и 2 на клеммах 13 и 19 разность между суммой температур 2 и 3 термопар и первой термопарой (TV + Tj).mi . 5 (When the thermo-EMF changes at terminals 9 and 15, the temperature Tj ,, measured by thermopile 1 is measured, and the temperature measured by thermocouple 2 is determined at terminals 8 and 12, at terminals 16 and, 18, the temperature Tj measured by thermocouple 3, the temperature difference T, Tj between the thermocouple is determined at terminals 10 and 17; the temperature difference between thermocouples 1 and 2 at terminals 11 and 14; the difference between the sum of temperatures 2 and 3 of the thermocouple and the first thermocouple at terminals 13 and 19 (TV + Tj) .mi. 5 (
