Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-2, the anti-vibration thermal resistor special for the screw air compressor comprises a platinum thermal resistor 2 and a protection tube 1, wherein a thin film element 2a is arranged in the platinum thermal resistor 2, and a thin film element 2a with a division number of Pt1000 is adopted, is 2mm square and has a thickness of about 1 mm. The thin film element 2a has small volume and is manufactured by adopting a film pressing process, so that the thin film element has good shock property; the sensitivity of the Pt1000 graduation number is 10 times of that of the common Pt100 graduation number, and the temperature change of the air compressor can be quickly reflected.
