Abstract
The utility model discloses an armoured thermal resistor including a stainless steel protective tube and thermal resistors; and the thermal resistors are arranged in an inner cavity of the stainless steel protective tube and connected with a terminal row in a conjunction box through outgoing wires, and at least two thermal resistors which are connected in series are disposed. According to the armoured thermal resistor, at least two common thermal resistors are connected in series, the precision of temperature measurement can be raised by adding variance in resistance, and the cost is reduced; the common thermal resistors are convenient to maintain and replace, the versatility is high, and the difficulty caused by a customization thermal resistor is prevented.
Description
Technical field
The utility model relates to thermal resistance field, is specifically related to a kind of armoured thermal resistance.
Background technology
Thermal resistance is the conventional temperature element of a kind of every profession and trade, the characteristic increasing with temperature according to the resistance of metal is made, platinum or copper are to apply at present maximum thermal resistance materials, but it is lower that these apply maximum Thermistor Temperature Measurement precision, take platinum resistance thermometer sensor, as example, 1 ohm of its change in resistance, represent 2.5 degrees Celsius of temperature variation, for the high occasion of temperature control requirement, ordinary hot resistance cannot meet the demands, and can only customize the high high-precision thermal resistance of price.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of armoured thermal resistance, can solve existing ordinary hot resistance and cannot meet the requirement of high precision occasion, causes customizing the problem of the high high-precision thermal resistance of price.
The utility model is achieved through the following technical solutions:
An armoured thermal resistance, comprises stainless steel protection pipe, thermal resistance, and described thermal resistance is positioned over stainless steel protection tube cavity, by extension line, is connected in the terminal row in terminal box, and described thermal resistance has two at least, and described at least two thermal resistances series connection is integrated.
Further improvement of the utility model scheme is, described each thermal resistance also correspondence is provided with isolated tube, and described thermal resistance is arranged at the lower end of isolated tube, and the extension line of described thermal resistance is from bottom to top through isolated tube.
Further improvement of the utility model scheme is that described isolated tube is made by pottery.
Further improvement of the utility model scheme is that the model of each thermal resistance is identical.
Further improvement of the utility model scheme is that described stainless steel protection tube cavity is filled with magnesia powder.
The utility model advantage is compared with prior art:
One, the ordinary hot resistance series connection of at least two is used, increased change in resistance amount to improve thermometric precision, reduced cost;
Two, ordinary hot resistance is convenient to safeguard, change highly versatile, the maintenance difficulties of avoiding custom heat resistance to bring.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
