Protective layer.
In such scheme, by arrange Wear-resistant, high-temperature resistant protective layer can service life of Elongated cable wire, save production cost.
Preferably, described platinum resistance thermometer sensor, is double resistance, and a described double resistance include an operating resistance and a standby resistance.
In such scheme, when operating resistance goes wrong, another standby resistance of interchangeable carries out temperature monitoring.
Preferably, described platinum resistance thermometer sensor, uses three-wire system gage system to connect.
Preferably, operating resistance is drawn three cables and is connected outside display instrument, and be energized work, and standby resistance is drawn three
Bar cable no power stays with standby.
Preferably, described platinum resistance thermometer sensor, is PT100 platinum resistance.
Preferably, described containment vessel is fixed at grinding roller bearing.
Preferably, described containment vessel is located in the bearing of Roller of Coal Grinder, and described cable is by the pipe at Roller of Coal Grinder bearing
Road is drawn.
After using technique scheme, this utility model compared with prior art has the advantages that
1, this utility model is directly connected between cable and platinum resistance thermometer sensor, and is not attached by traditional conversion terminal,
Then avoid and cause cable to hold caducous problem by conversion terminal line, simultaneously by leaving additional length inside grinding roller,
The stress of node between cable and platinum resistance thermometer sensor, the link node being effectively reduced between cable and platinum resistance thermometer sensor, can be buffered
Fracture.
2, described cable includes wire and the insulating barrier being coated on outside wire, and described insulating barrier is externally provided with Wear-resistant, high-temperature resistant protective layer,
By arrange Wear-resistant, high-temperature resistant protective layer can service life of Elongated cable wire, save production cost.
3, described platinum resistance thermometer sensor, is double resistance, including the standby resistance of an operating resistance and one, then when operating resistance generation problem,
The cable of standby resistance can be connected display instrument and detect roll temperature.
