Abstract

The utility model relates to a contact and non-contact compound temperature measuring sensor, and belongs to a temperature measuring sensor. A temperature sensing and spying pipe and a positioning ring are inserted in the center hole of a big flange of a joint element which is welded by a big flange, a small flange and a steel pipe, are thermally insulated and are sealed as a contact part. A non-contact part is coaxially assembled with the contact part in a back cover which is welded with a big flange, composed of a photoelectric conversion probe which is provided with conducting wires. The utility model also comprises a voltage-resistance sight glass which is distant between the contact part and the non-contact part. The utility model takes advantages of contact temperature sensors and non-contact temperature sensors as integration. The utility model takes advantages of contact temperature sensors and non-contact temperature sensors as integration. The utility model has the advantages of direct and accurate temperature measurement, high temperature resistance and corrosion resistance, and can be widely used for temperature measuring occasions of petroleum, chemical industry, metallurgy, building materials, etc.

Description

Contact and contactless compound temp. mesauring sensor
The utility model belongs to temperature probe.
The present temperature probe that uses in fields such as oil, chemical industry, metallurgy, building materials has contact and contactless two kinds.Contact as platinum rhodium thermocouple commonly used etc. owing to be directly to place point for measuring temperature, thermometric is directly, accurately.But its life-span is short, not corrosion-resistant, rapid wear.Though contactlessly can overcome above-mentioned shortcoming, but not as its directly and accurately.
The purpose of this utility model provides and a kind ofly collects both for the contact noncontact compound temperature sensor of one.
Main points of the present utility model are to spy out pipe and centring ring insertion by greatly by temperature-sensitive, the annular space of the web member that little flange and steel pipe are welded adds asbestos packing, the filler pad, the filler securing member carries out the contact portion that heat-insulating and sealing is formed, with the opto-electronic conversion probe that place the bonnet that be welded with Da Lan in and insert web member coaxial with it, probe connects the noncontact part of forming by binding post and the wiring nut in the insulating sleeve on lead and the bonnet, and is separated with withstand voltage visor between the two mutually, the visor pad, and with nut, the contact noncontact compound temperature sensor that spiral shell select etc. is connected as one and is formed.
Accompanying drawing is contact noncontact compound temperature sensor structural representation.
As seen from the figure: the temperature-sensitive of being made by metallic ceramics or corundum is spied out pipe 2 and is inserted in the web member 10 that is welded by large and small flange and steel pipe in the big flange center hole with its fixing centring ring 8, spy out that pipe 2 adds asbestos packing 7, filler pad 6 with annular space between the web member 10, filler securing member 5 carries out heat insulation and seal at temperature-sensitive, formed the contact portion of sensor; At its corresponding other end, the noncontact part that assembling coaxial with it arranged, it is by being contained in the bonnet 15 that is welded with big flange and inserting opto-electronic conversion probe 20 in the web member 19, probe by lead be located at bonnet on binding post 17, wiring nut 18 in the insulating sleeve 16 connect and form; Between contact and noncontact part, be separated with withstand voltage visor 12, visor pad 11 mutually, and have nut 14, packing ring 21 and spiral shell select 9, packing ring 23, nut 13 to be connected as one, and be lined with asbestos gasket 22 between the big flange of two web members, formed contact noncontact compound temperature sensor.
During use, can be with the above-mentioned contact noncontact compound temperature sensor that assembles, through the little flange of web member 10 1 ends and be connected on the body of heater 1 blue 3 usefulness of perrin process fixedly spiral shell select 24 fix, be lined with asbestos gasket 4 between two flanges.Like this, spy out pipe and be heated to same temperature when the high temperature of body of heater directly will contact temperature-sensitive, the contact temperature-sensitive is spied out pipe temperature transition is become light signal, by withstand voltage visor light signal is passed to the opto-electronic conversion probe, (the infrared electro switching device in the probe) converts light signal to electric signal, can join directly with the digital interior temperature of coming out of the stove that shows with secondary instrument through lead and binding post.The utility model can be used its fundamental error in 700~1600 ℃ of temperature-measuring ranges :≤± 20 ℃, and withstand voltage 1.0MPa.
Contact noncontact compound temperature sensor integrates the advantage of contact and non-contact temperature sensor, had concurrently contact thermography directly, the inherent characteristics such as anticorrosive, high temperature resistant of accurate and non-contact temperature measuring, highly sensitive, novel structure.Press, have under the occasion of corrosion at high temperature, band, prolonged serviceable life greatly, substitute thermocouple temperature measurement, saved precious metal, reduced cost.
The utility model can be widely used in oil, chemical industry and metallurgy, building materials etc., and all have the temperature survey of the medium of corrosion to thermopair, have remarkable economical and social benefit.
