Overview:
The universal bimetal thermometer is an industrial bimetal thermometer. The main element is a multi-layer metal sheet composed of two or more metal sheets laminated together. An instrument that can automatically and continuously record changes. In order to improve the temperature measurement sensitivity, the metal sheet is usually made into a spiral coil shape. When the temperature of the multi-layer metal sheet changes, the amount of expansion or contraction of the metal in each layer varies, causing the spiral coil to roll up or loosen. Because one end of the spiral coil is fixed and the other end is connected to a freely rotating pointer, the two metals have different body changes when the temperature changes, so they will bend. One end is fixed, and the other end is displaced with temperature changes, and the displacement amount is close to a linear relationship with air temperature. The self-recording system is composed of a self-recording clock and a self-recording pen. The self-recording pen is connected to the amplifying lever and manipulated by the sensing element. Therefore, when the bimetallic plate senses the temperature change, the pointer can be indicated on a circular scale Temperature comes. The temperature measurement range of this instrument is 200~650℃, which is about 1% of the two passes of the scale.
Features:
1. On-site temperature display, intuitive and convenient; safe and reliable, long service life;
2. A variety of structural forms can meet different requirements.
working principle:
The bimetallic thermometer is based on a bimetallic sheet wound into a ring shape. When one end is heated and expanded, the pointer is driven to rotate, and the working instrument will display the corresponding temperature value.
