Description
Technical field
The invention belongs to thermometer technical fields, and in particular to a kind of micro armoured watt of temperature thermometer of leakproof.
Background technique
In the production such as chemical industry, metallurgy, it is all be unable to do without the detection of temperature, in these temperature detections, can inevitably allow temperature
Meter encounters the mordant liquid of some bands, if liquid enters gauge outfit, will cause thermometer damage, in some production operations
In, it is sometimes desirable to transient temperature is measured, common thermocouple wire has error, and subtleer thermo wires is needed to measure.
Summary of the invention
To solve the above problems, using fine metal the invention discloses a kind of micro armoured watt of temperature thermometer of leakproof
Thermo wires, make to measure it is more accurate, can prevent measurement when corrosive liquid enter gauge outfit, damage.
In order to achieve the above objectives, technical scheme is as follows:
A kind of micro armoured watt of temperature thermometer of leakproof, including metal thermo wires, protection pipe, gauge outfit, instrument board, insulating layer, it is described
Protection pipe is connected to gauge outfit lower end, and the insulating layer is wrapped in protection pipe, and the metal thermo wires, which is wrapped in insulating layer, to be connected
It connects on gauge outfit, the instrument board is at gauge outfit front.
Preferably, the metal pair wire material is copper constantan.
Preferably, the metal thermo wires diameter is 100 μm.
Preferably, the insulating layer material is magnesia.
Preferably, the gauge outfit and protection pipe junction are provided with flange and rubber pad.
The beneficial effects of the present invention are:
Present invention employs fine metal thermo wires, make to measure it is more accurate, can prevent measurement when corrosive liquid enter gauge outfit,
It damages.
Detailed description of the invention
