Description
Technical field
The present invention relates to a kind of water analysis sensor, the temperature survey dress in more particularly to a kind of water analysis sensor
Put.
Background technology
The primary signal that online water analysis instrument sensor is used for water quality index detects, including the pH value of water quality, oxidation are also
Former current potential value ORP, electrical conductivity, dissolved oxygen, chlorine residue, turbidity, ion concentration, concentration of suspension and temperature etc..
As shown in figure 1, the temperature measuring equipment of water analysis at this stage is to take stainless steel casing 1 ', by thermo-sensitive resistor 2 '
It is placed in the cavity of stainless steel casing 1 ', then carrying out simple embedding using epoxy resin embedding adhesive forms epoxy resin layer 3 ',
To have the function that fixed and seal.Because the conduction efficiency of stainless steel casing 1 ' is relatively low, simultaneously because epoxy pouring sealant is to temperature
The conduction efficiency of degree is limited, so as to cause to test the shortcomings of response time is longer, reaction is slow, and measuring accuracy is not high.
The content of the invention
The technical problem to be solved in the present invention, in the temperature measuring equipment in a kind of water analysis sensor is provided, lead to
Replacing shell and embedding structure are crossed, conduction efficiency is effectively lifted, so that the efficiency and precision of temperature survey all obtain
Effectively lifting.
What the present invention was realized in：A kind of temperature measuring equipment in water analysis sensor, including foreign white copper upper casing,
Ceramic lower casing, thermo-sensitive resistor, heat-conducting silicone grease interlayer and epoxy sealing glue-line；The thermo-sensitive resistor is located at the foreign white copper upper casing
In the upper end of the cavity surrounded with the ceramic lower casing, the heat-conducting silicone grease interlayer is filled in the upper end of the cavity and coated
Around the thermo-sensitive resistor, the epoxy sealing glue-line be then filled in the lower end of the cavity and with the heat-conducting silicone grease every
Layer linking.
Further, the interface of the heat-conducting silicone grease interlayer and the epoxy sealing glue-line is three sections of arcwall faces, including
Outer arc, middle arc and inner arc, the outer arc and inner arc concave towards the heat-conducting silicone grease interlayer, and the middle arc concaves towards the epoxy pouring sealant
Layer.
The invention has the advantages that：The present invention makes conduction efficiency effectively be carried by changing shell and embedding structure
Rise, so that the efficiency and precision of temperature survey are all effectively lifted.
Brief description of the drawings
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the axial sectional structure chart of the temperature measuring equipment of water analysis at this stage.
Fig. 2 is the axial sectional structure chart of the temperature measuring equipment of water analysis of the present invention.
Fig. 3 is Fig. 2 partial enlarged drawing.
Embodiment
Refer to shown in Fig. 2, the temperature measuring equipment in water analysis sensor of the invention, including foreign white copper upper casing 1,
Ceramic lower casing 2, thermo-sensitive resistor 3, heat-conducting silicone grease interlayer 4 and epoxy sealing glue-line 5；It is white that the thermo-sensitive resistor 3 is located at the ocean
In the upper end for the cavity that copper upper casing 1 and the ceramic lower casing 2 surround, the heat-conducting silicone grease interlayer 4 is filled in the upper of the cavity
End in and coat around the thermo-sensitive resistor 3, the epoxy sealing glue-line 5 be then filled in the lower end of the cavity and with institute
Heat-conducting silicone grease interlayer 4 is stated to be connected.
Refer to shown in Fig. 3, the interface of the heat-conducting silicone grease interlayer 4 and the epoxy sealing glue-line 5 is three sections of arcs
Face 6, including outer arc 61, middle arc 62 and inner arc 63, the outer arc 61 and inner arc 62 concave towards the heat-conducting silicone grease interlayer 4, in described
Arc 62 concaves towards the epoxy sealing glue-line 5.This have the advantage that embedding and heat conduction layering progress, heat-conducting silicone grease interlayer 4 are negative
Heat conduction is blamed, and epoxy sealing glue-line 5 is then responsible for the seal request of device.Rather than the casting glue heat conduction bad directly with thermal conductivity
And sealing.
The present invention makes conduction efficiency effectively be lifted by changing shell and embedding structure, so that temperature survey
Efficiency and precision are all effectively lifted.
Although the foregoing describing the embodiment of the present invention, those familiar with the art should manage
Solution, the specific embodiment described by us are merely exemplary, rather than for the restriction to the scope of the present invention, are familiar with this
The equivalent modification and change that the technical staff in field is made in the spirit according to the present invention, should all cover the present invention's
In scope of the claimed protection.
