Abstract

The invention discloses an ultrahigh pressure armored thermocouple comprising an armored thermocouple and a lead device. The ultrahigh pressure armored thermocouple is characterized by also comprising a compensation lead, a sealing tube, a fixed device and an adjusting device, wherein one end of the armored thermocouple is connected with one end of the compensation lead through the lead device; the sealing tube is sleeved on the armored thermocouple; and the fixed device and the adjusting device are sleeved on the sealing tube. The invention has the characteristics of high voltage resistance, high measuring precision, sensitive reaction, economy and practicability, and can be applicable to ultrahigh pressure (the pressure is more than 200MPa-280MPa) places, such as the fields of oil exploration, chemical measurement, scientific experiments and the like.

Description

technical field [0001] The invention relates to an armored thermocouple, in particular to an ultra-high voltage armored thermocouple, which is an improvement to the structure of the existing armored thermocouple, belongs to the manufacturing technology of the armored thermocouple, and is suitable for ultra-high pressure (pressure greater than 200Mpa) ~280Mpa) places, such as oil exploration, chemical measurement, scientific experiments and other fields. Background technique [0002] The existing ultra-high voltage armored thermocouple is composed of a junction box, a temperature measuring element, an outer protection tube and a measurement protection sleeve. The junction box is provided with a lead nut, a sealing washer, a junction seat, a fixed bracket and a junction box cover. The measuring protection sleeve of the thermocouple measurement part is a tapered tube, which is drilled from a solid alloy steel bar, and the temperature measuring element is placed in the inner hol...
