Detailed description of the invention
Name a preferred embodiment, and become apparent from intactly illustrating the present invention in conjunction with accompanying drawing.
The present invention provides a kind of floor heating transmitter, and this transmitter is the monitoring system for floor heating heating, specifically, is used to the pressure by the fluid in floor heating hot duct and is converted to voltage signal, is transmitted further to control terminal.
As Figure 1-3, floor heating transmitter provided by the invention includes body 1 and a shell 2, and basis is internal is provided with a hollow bulb 11, and this hollow bulb 11 is used for housing sensor element 3.
Sensor of the invention element 3 includes elastomer 31, resistance silicon 32 and a compensating plate (not shown).Wherein, elastomer 31 and resistance silicon 32 adopt micro-molten technology to be sintered into one, and compensating plate is pasted onto on elastomer 31.Owing to the volume of whole transmitter has much relations with the volume of sensor element 3, adopt micro-molten technology can realize combining elastomer 31 and the resistance silicon 32 of small size, the volume making whole transmitter is also reduced, thus meeting the requirement that floor heating heating monitoring system is little to transmitter volume.Adopting resistance silicon 32 can improve output sensitivity compared to traditional Wheatstone bridge, compensating plate then can carry out linear compensation and temperature-compensating so that the voltage signal of output reaches effects of demand.
This sensor element 3 is placed in the bottom of hollow bulb 11, and the pressure of the fluid from floor heating hot duct is born in the bottom surface of elastomer 31.In order to seal, between the bottom surface of the bottom surface of elastomer 31 and hollow bulb 11, it is provided with an O RunddichtringO 4.
Being covered with a packing ring 5 on sensor element 3, the edge of packing ring 5 is provided with through hole 51, and the wire 6 being connected with compensating plate passes from through hole 51, and is connected to the circuit board 21 being located in shell 2.Packing ring 5 is also covered with a press strip 7.
Having four jacks on circuit board 21, these jacks weld with four contact pins 22 penetrating shell 2.These four contact pins 22 are arranged on the plug connector 8 of shell 2 upper end, and plug connector 8 controls terminal with one again and is connected.
Being provided with a junction 9 in the bottom of body 1, connecting portion is provided with two cannelures, near the cannelure 91 of top be for floor heating hot duct clamping.It is embedded with an O RunddichtringO 93 so that seal between this transmitter and pipeline in the cannelure 92 of lower section.
Additionally, the shell 2 of this transmitter is sheathed on body 1, and with the clamping of described body 1.The material of body 1 and shell 2 is plastics.So can more save production cost.
In the process of assembling, mounting O-shaped sealing ring 4, sensor element 3 and packing ring 5 successively in hollow bulb 11, and wire 6 is passed from the through hole 51 packing ring 5 edge, press under packing ring after being positioned by professional equipment subsequently, make O RunddichtringO 4 compression, in this case, then by press strip 7 cover on packing ring 5, it is ensured that the compression of packing ring 5, sensor element 3 and O RunddichtringO 4 seals.After the circuit board 21 wire 6 being connected on shell 2, finally by shell 2 close-fitting to body 1.
During use, by the cannelure 91 on connecting portion 9 and the clamping of the corresponding interface on pipeline, completing the connection of transmitter and pipeline, this connected mode is simple, convenient, it is possible to achieve quickly install and dismounting.
Although the foregoing describing the specific embodiment of the present invention, it will be appreciated by those of skill in the art that this is merely illustrative of, protection scope of the present invention is defined by the appended claims.Those skilled in the art is under the premise without departing substantially from principles of the invention and essence, it is possible to these embodiments are made various changes or modifications, but these change and amendment each falls within protection scope of the present invention.
