Abstract
The invention belongs to an electrical heating device, and in particular relates to an electrical heating device with a temperature measuring function. The electrical heating body with the temperature measuring function comprises a metal protective shell, an electrical heating element, an insulation tube, a filling material, a front plugging board and a rear plugging board, wherein the insulation tube (3) is installed between the front and the rear plugging boards through positioning holes in the front plugging board (7) and the rear plugging board (8), the surface of the insulation tube (3) is wound with the electrical heating element (2), and two leads of the insulation tube (3) are respectively led out of the rear plugging board (8). The electrical heating device is characterized in that the front end of the front plugging board (7) is also provided with a temperature sensitive element (4), two ends of a high-temperature lead (5) of the temperature sensitive element penetrate through the front plugging board (7) and then lead out of the rear plugging board (8). The electrical heating device can be used for heating and measuring the temperature in a manner that a hole is processed in a heated body, thereby simplifying the structure of the heated body; and a temperature measuring element is close to the heating tube, thus the temperature measuring accuracy can be improved.
Description
Technical field
The invention belongs to electric heating body, particularly a kind ofly be with thermometric electric heating body.
Background technology
Electric heating tube only had heating function in the past, and itself does not have measurement function.Except the installing hole of needs processing electrothermal tube, also need to process a hole more separately on the heated object, be used for installing some temperature-sensing element (device)s such as thermocouple.Calandria is structurally very inconvenient, and the measurement of heating-up temperature is also had deviation.
Summary of the invention
The purpose of this invention is to provide a kind of can the heating, can also measure the thermometric electric heating body of being with of heated object temperature.Simplify the structure of heated object, improve temperature measurement accuracy.
The object of the present invention is achieved like this, and accompanying drawings is as follows:
A kind of electric heating body with thermometric; form by metal coating housing, electrical heating elements, insulated tube, packing material, forward and backward shutoff plate; described insulated tube 3 is installed between the forward and backward shutoff plate by the location hole on preceding shutoff plate 7 and the back shutoff plate 8; insulated tube 3 surfaces are wound with electrical heating elements 2; two lead-in wire is drawn from back shutoff plate 8 respectively; shutoff plate 7 front ends also are equipped with a temperature-sensing element (device) 4 before described; preceding shutoff plate 7 is passed at the two ends of its high temperature wire 5, draws from back shutoff plate 8.
Described temperature-sensing element (device) 4 is occasionally other temperature-sensing element (device)s of thermoelectricity.
Described insulated tube 3 is equipped with electrical heating elements 2 for there is helicla flute on magnetic tube and surface in the helicla flute, and can determine groove width and spacing according to watt level.
Described insulated tube 3 radially has a hole near the helicla flute bottom of preceding shutoff plate 7 one ends, and electrical heating elements 2 lead-in wires one end C enters insulated tube 3 inside by this hole and draws from back shutoff plate 8.
The packing material 6 that has good heat resistance, insulating properties and thermal conductivity at inner all the gap padding and compactings of described electric heating body.
The invention has the beneficial effects as follows:
But can heat and thermometric, hole of processing gets final product on the heated object, has simplified the structure of heated object, and temperature element is very near apart from heating tube, can improve temperature measurement accuracy.
