Embodiment Construction

[0011] The present invention provides a sheathed thermocouple thermometer, and the present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0012] figure 1 is the assembly drawing of the armored thermocouple thermometer, figure 2 Is the armored thermocouple thermometer structure diagram. The armored thermocouple thermometer mainly includes a temperature measuring wire plug 3, an inductor 4, a seal 5, and a temperature measuring rod 6, and is installed on the plug 2 at one end of the ultra-high pressure vessel 1. The temperature measuring rod 6 is made of stainless steel, and the surface is plated with a layer of nickel-chromium alloy; the temperature measuring rod 6 passes through the temperature measuring wire plug 3 and is connected to the sensor 4 at the other end to transmit temperature signals at any time; the sealing member 5 is made of Alloy rings, ○-rings and PTFE gaskets are stacked on th...

Abstract

The invention belongs to the thermocouple thermometer field and particularly relates to a sheathed thermocouple thermometer. The invention mainly comprises a temperature measurement wire plug, a sensor, a sealing element and a temperature measurement rod which is made of stainless steel and coated with a layer of Ni-Cr alloy. The temperature measurement rod is threaded through the wire plug to be connected with the sensor at the other end; the sealing element is formed by bushing an alloy ring, an O-ring and a PTFE gasket onto the temperature measurement rod; a taper face is arranged at the end of the temperature measurement wire plug to match the taper face of a container plug; after the temperature measurement rod and the sensor are fixedly connected with the temperature measurement wire plug through the sealing element, the temperature measurement wire plug is connected with the container plug through threads and finally is threaded through the taper face at the end. The temperature measurement is accurate and the error is plus or minus 0.001 DEG C and the maximum bearing-pressure can reach 600MPa; the design for the sealing is excellent; and the structure is simple, the operation is easy and the cost can be lowered.

Description

technical field [0001] The invention belongs to the field of thermocouple thermometers, in particular to an armored thermocouple thermometer. Background technique [0002] Temperature is a parameter that needs to be controlled in the process of food processing, and measuring the change of food temperature has also become an important task. Thermocouple thermometers are especially suitable for on-site temperature measurement of static and dynamic solid surface temperatures, liquids, gases and slits. Thermocouple thermometers are widely used in rubber, plastic, chemical, chemical fiber, paper, aluminum processing, mold and other industries. In food ultra-high pressure equipment, temperature measurement is difficult to achieve, mainly by measuring the temperature of the interlayer of the container to indirectly reflect the temperature of the internal material. The difficulties encountered in temperature measurement during ultra-high pressure processing of food are: (1) the te...
