seismic at the scene of the bimetallic thermometer display temperature, intuitive and convenient; Safe and reliable, long life; Many kinds of structure forms, can meet different requirements. No mercury pollution, easy reading, strong shock resistance. Protection is 1 gr18ni9ti stainless steel and molybdenum titanium tubes, pressure and corrosion ability. Core-pulling thermometer can not stop short time machine maintenance or replacement. One-piece type axial, radial and 135 o, universal type, such as the variety is complete, suitable for all kinds of the needs of the installation. Working principle of the seismic electric contact bimetallic thermometer is based on the ring around the made of bent bimetallic strip. Side heated expands, turns the pointer, the instrument will show should value, and prevent environmental vibration within the bimetallic thermometer filling or silicone oil of bimetallic thermometer display section and some separation measure to achieve seismic effect. Seismic bimetallic thermometer and points one-piece seismic electric contact bimetallic thermometers and separate seismic electric contact bimetallic thermometer. Execution standard JB/T8803 - 1998 GB3836- Dial 83 other parameters nominal diameter: precision grades of 60, 100, 150: ( 1. 0) 1. 5 thermal response time: 40 s or less protection grade: IP55 Angle adjustment error: error of Angle adjustment shall not exceed the range of 1. 0% return difference: return difference should be no greater than the basic error limits the value of the repetitive: repeatability limit range should not be greater than 1/2 of the upper limit value of basic error.
