Need to what kind of thermometer for temperature control and alarm automatically?

Electric contact bimetallic thermometer is the use of two kinds of different temperature of metal expansion coefficient, thermal conductivity sensor is made of, make full use of the principle of heat bilges cold shrink, solved the temperature in the process of temperature measurement accuracy, in order to improve the bimetallic thermometer temperature measurement sensitivity, will usually made of metal spiral coil shape, when multi-layer metal temperature change, the layers of metal expansion or contraction, makes the spiral coil rolled up or loose, as a result of the spiral coil end fixed and the other end connected to a free rotating pointer. According to the electric contact bimetallic thermometer pointer plate with the direction of protecting tube connection bimetallic thermometer can be divided into axial, radial and 135 & deg; To type and universal type four. (1) the axial type bimetallic thermometer: pointer vertical connection tube plate and protection. (2) the radial type bimetallic thermometer: pointer GuanPing line connection plate and protection. ③135度; The bimetallic thermometer: pointer tube plate and protection into 135 & deg; The connection. (4) universal type bimetallic thermometer: pointer plate connected to the protecting tube Angle can be arbitrary adjustment. Electric contact bimetallic thermometer features: 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. The axial, radial, 135 o, universal type, such as the variety is complete, suitable for all kinds of the needs of the installation.
