Abstract
The invention discloses a compressed spring fixing-type thermocouple and a temperature measurement method. The traditional thermocouple is inconvenient to mount in the case of temperature measurement and thus temperature measurement is inaccurate and difficult. A thermocouple tape has no flexible prolonged wire and can not be bent freely, the time amount is large, and the use is inconvenient. The compressed spring fixing-type thermocouple comprises a group of thermocouples (5); a flexible prolonged wire (10) is arranged between the group of thermocouples; one end of the group of thermocouples is provided with leads (6); each load is provided with a U-shaped clip (7); the other end of the group of thermocouples is sleeved with a spring (9); the spring is sleeved with a clamping sleeve (3); the clamping sleeve is provided with a clamping sleeve screw (4); the lowest end of the group of thermocouples is provided with a protection pipe (1); the lower end of the spring is externally provided with a locking snap spring (8); and the locking snap spring is connected with a connection bolt (2).
Description
technical field:
the present invention relates to a kind of spring-pressing fix type thermocouple and temp measuring method.
background technology:
thermopair is temperature element conventional in temperature measuring instrument, its direct measuring tempeature, and temperature signal is converted to thermopower signal, is converted to the temperature of measured medium by electric meter (secondary instrument).The profile of various thermopair is often far from it because of needs; but their basic structure is roughly the same; usually be made up of major parts such as thermode, insulation sleeve protection tube and terminal boxes; usually and Displaying Meter, recorder and electronic controller support the use, traditional thermopair is that even installation is inconvenient to cause that thermometric is inaccurate to encounter difficulties at thermometric.Thermopair band does not have soft extension lead, can not free bend, and time number is large, uses inconvenience.
summary of the invention:
the object of this invention is to provide a kind of spring-pressing fix type thermocouple and temp measuring method.
above-mentioned object is realized by following technical scheme:
a kind of spring-pressing fix type thermocouple; its composition comprises: one group of thermopair; between one group of described thermopair, there is soft extension lead; one end of one group of described thermopair has lead-in wire; described lead-in wire has the capable card of U; a described honor thermopair other end outer cover has spring; described spring outer cover has cutting ferrule; described cutting ferrule has cutting ferrule screw; one group of described thermopair has protection tube bottom; described lower spring end outside has locking jump ring, and described locking jump ring is connected with coupling bolt.
the method of described spring-pressing fix type thermocouple thermometric; spring-pressing fix type thermocouple temperature-measuring range is at 0-600 DEG C; the Material selec-tion of protection tube is stainless steel; the length of coupling bolt is 35-70mm; first spring-pressing fix type thermocouple is fixedly mounted on testee before measurement, first coupling bolt is tightened on testee, then thermopair is close to measured object; tighten cutting ferrule screw, locking cutting ferrule of finally screwing on.
the method of described spring-pressing fix type thermocouple thermometric; spring-pressing fix type thermocouple and temp measuring method are; thermopair is a kind of temperature-sensing element; it is primary instrument; its direct measuring tempeature; and temperature signal is converted to thermopower signal, then convert the temperature of measured medium to by electric meter secondary instrument; Thermocouple temperature measurement is the material conductor composition closed-loop path of two kinds of different components, when two ends exist thermograde, just has electric current and passes through, now just there is electromotive force thermopower between two ends, so-called Seebeck effect that Here it is in loop; The homogeneous conductor of two kinds of different components is thermode, and one end that temperature is higher is working end, and one end that temperature is lower is free end, under free end is in stationary temperature usually; According to the funtcional relationship of thermopower and temperature, make thermocouple indexing table; Phasing meter obtains under the condition of free end temperature 0 DEG C time, and different thermopairs has different phasing meter; When accessing the third metal material in For Thermocouple Circuit, as long as the temperature of this material two contacts is identical, the thermoelectrical potential that thermopair produces will remain unchanged, namely not by the impact in the third metal access loop; Therefore, when thermocouple temperature measurement, accessible measurement instrument, after recording thermopower, can know the temperature of measured medium.
beneficial effect:
1. the present invention adopts spring-pressing fix type thermocouple, thermopair has that precision is high, economy and the wide feature of temperature, and usable range is comparatively wide, homogeneity and interchangeability good, thermocouple measurement end and measured object are close to by stage clip by spring-pressing fix type thermocouple, to improve reliability and the accuracy of measurement.Support the use with Displaying Meter etc., directly can measure the temperature within the scope of 0-600 DEG C.Thermopair, can free bend with soft extension lead, has time number little, and the feature such as easy to use, is applicable to the industry such as plastic extruder, light textile, food.
