The working characteristics of pointer bimetallic thermometer

Pointer bimetallic thermometer work features: pointer bimetallic thermometer is a round shape into threaded heat bimetallic strip as thermal devices, and put it in a protective sleeve tube, one end is fixed, known as the fixed end, the other end of the connection on a thin shaft, a free end. Spool at the free end is equipped with a pointer. When the temperature changes, the resulting thermal devices the free end of the rotation, drive the thin axis from the Angle of the pointer changes, the corresponding temperature indicator on the dial; Straight table by steering transmission mechanism drive the pointer changes. Due to the thermal device has a linear relation with temperature changes, so the position of the pointer indicated by bimetallic temperature sensor, that is, the temperature of the measured values. Watchcase material can be steel plate, casting alloy and stainless steel plate; Detecting element also have core-pulling structure; Adjustable Angle meter part of the temperature sensor by means of the corrugated pipe, Angle of body parts, such as can be from the Angle to the straight or from the straight to the Angle at any Angle. Main features: pointer bimetallic thermometer field display temperature, intuitive and convenient; Safe and reliable, long life; Core-pulling thermometer can not stop short time machine maintenance or replacement. The axial, radial and 135 & ordm; Type, universal type, such as complete varieties, suitable for all kinds of the needs of the installation. Working principle of the pointer bimetallic thermometer WSS series bimetallic thermometer is based on the orbit into ring sex of bimetallic strip bent. End is heated expands, turns the pointer, the instrument will show thermoelectric potential should value. Main technical parameters of pointer bimetallic thermometer Angle adjustment error: error of Angle adjustment shall not exceed the range of 1. 0% return difference: the thermometer shall not return difference more than the absolute value of basic error limits repeatability: the thermometer repeatability limit scope shall not cut more than 1/2 basic error limits the absolute value of
