Abstract
The utility model relates to a rod type temperature controller, which is composed of a sensing part and switch parts. The sensing part comprises a metal rod and a ceramic pipe sleeved outside the metal rod, and the metal rod is fixed with the lower end of the ceramic pipe. When the sensing part is heated, the metal rod is matched with one or a plurality of switch parts through ceramic bars. The rod type temperature controller has the advantages that reliability is high, and the controller can be used for 200 thousand times due to a fact that different linear thermal expansion coefficients of the metal rod and the ceramic pipe are used for controlling opening and closing of a switch; detection temperature is high, and the highest detection temperature can be 1200 DEG C; and the controller is convenient to install due to a fact that the controller uses a radiation heating so that the controller does not need to attach to a detected surface.
Description
Technical field
The utility model relates to a kind of temperature control equipment, especially a kind of rod-type temperature controller.
Background technology
Conventional temperature controller needs and tested surface fits tightly, and inconvenience is installed, and has shortcomings such as heatproof is low.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provide a kind of easy for installation, thermometric is high, the rod-type temperature controller of good reliability.
The utility model solves the technical scheme that its technical matters adopts: this rod-type temperature controller, form by transducing part and switch sections, described transducing part comprises Metallic rod and is sheathed on its outside porcelain tube, Metallic rod and porcelain tube lower end are fixed, and Metallic rod cooperates with one or several switch sections by the porcelain bar when transducing part is heated.
As preferably, described switch sections is made up of fixed contact and the shell fragment that is mated, when transducing part is heated Metallic rod by with shell fragment contact gauge tap closure partly.
The effect that utility model is useful is: utilize the different closures of coming gauge tap of the thermal linear expansion coefficient of Metallic rod and porcelain tube, the reliability height can reach 200,000 serviceable life; Thermometric height, highest detectable temperature can reach 1200 ℃; Easy for installation, adopt radiation heating, need not fit with measured surface.
Description of drawings
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the structural representation of embodiment 2;
Description of reference numerals: porcelain tube 1, Metallic rod 2, porcelain bar 3, fixed contact 4, shell fragment 5.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment 1: as Fig. 1, this rod-type temperature controller, form by transducing part and switch sections, described transducing part comprises Metallic rod 2 and is sheathed on its outside porcelain tube 1, Metallic rod 2 and porcelain tube 1 lower end are fixed, switch sections is made up of fixed contact 4 and the shell fragment 5 that is mated, and Metallic rod 2 comes in contact the closure of gauge tap by porcelain bar 3 and shell fragment 5 when transducing part is heated.
Embodiment 2: as Fig. 2, have two switch sections in this rod-type temperature controller, each switch sections all is made up of one group of shell fragment 5 and fixed contact 4, Metallic rod 2 comes in contact the closure of controlling these switches simultaneously by the shell fragment 5 of porcelain bar 3 and each switch sections when transducing part is heated, and remainder is identical with embodiment 1.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
