Description
Technical field
The utility model is related to a kind of temperature sensor of the high-fire resistance of metal end subtype.
Background technology
At present, with the rapid development of economy, thermometer is the parameter that test is frequently necessary in practical application, in micro-wave oven
Need to realize system temperature by the measurement of temperature in field, the temperature inductor makes extremely important, and for measurement temperature
Kind of sensor is a lot, and thermal resistor is exactly one of them, and the Main Differences of existing various NTC temperature sensors are to wrap up
There is the transducing head structure difference of NTC themistor or NTC themistor chip very big, but no matter contour structures have great
Difference, its lead-out wire overwhelming majority is all PVC or resistant to elevated temperatures Teflon insulated conductors, in the prior art due to transducing head structure
Design is unreasonable and temperature measuring point working condition requirement is different so that the actual temperature measuring point of temperature sensor is with requiring that temperature measuring point is easily sent out
Raw deviation, so as to influence the functional reliability of temperature sensor, influences working effect.So how to provide one kind can be accurate in time
True reflected microwave furnace temperature, precise control of temperature turn into the problem of needing urgent solve at present.
The content of the invention
To solve the above problems, the utility model provides a kind of temperature sensor of high heat resistance.
The utility model provides a kind of temperature sensor, the mounting hole that it includes temperature-sensitive head, is connected with temperature-sensitive head,
The mounting hole is inserted in temperature-sensitive head, and temperature-sensitive head one end, which is provided with sleeve pipe, described sleeve pipe, is provided with CP lines, the set
Pipe sleeve is sealed with epoxy resin layer, the temperature-sensitive head in CP lines periphery, temperature-sensitive head and is provided with terminal.
Preferably, the temperature-sensitive head is coated with protective case, and described sleeve pipe diameter is consistent with protective case diameter.
Preferably, described sleeve pipe caliber is 2-4cm.
Preferably, the mounting hole is made up of stainless steel material.
After the utility model, its advantage is：
A kind of temperature sensor, the mounting hole that it includes temperature-sensitive head, is connected with temperature-sensitive head, the mounting hole is inserted in
In temperature-sensitive head, temperature-sensitive head one end, which is provided with sleeve pipe, described sleeve pipe, is provided with CP lines, and described sleeve pipe is enclosed on CP lines periphery,
It is sealed with temperature-sensitive head in epoxy resin layer, the temperature-sensitive head and is provided with terminal, its temperature detector high temperature resistant produced, zero power
Rate resistance value（R75）75 DEG C of ± 7% at of 7.241k Ω, B constants（0/100）3970K ± 2%, operating temperature range DEG C is -20
DEG C~200 DEG C.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model temperature sensor.
