Description SELECTION CRITERIA INSTALLATION AND USE FIELD INSTALLATION

Bimetal thermometer is a kind of field testing instrument suitable for measuring low and medium temperature, which can be used to directly measure the temperature of gas and liquid. Compared with glass thermometers, it has the advantages of no mercury harm, clear readings, and ruggedness. Our company produces a wide range of bimetal thermometers with various specifications and stable and reliable quality, which can be widely used in various departments in the fields of industry, agriculture, national defense and scientific research.

The bimetal thermometer (hereinafter referred to as the thermometer) uses a hot bimetal wound in a spiral shape as a temperature sensing element and is installed in a protective sleeve. One end is fixed (fixed end), and the other end (free end) is connected to a On a thin shaft, a pointer is mounted on the shaft end. When the temperature changes, the free end of the temperature sensing element rotates, and the pointer changes the temperature on the dial through a thin shaft.The straight thermometer drives the pointer through the steering transmission mechanism.The case material is steel plate and cast aluminum. Alloy, stainless steel plate. The head of the adjustable angle thermometer can be adjusted from angle to straight or from straight to angle with the help of bellows and corner mechanism.
The electric contact bimetal thermometer adds components such as an electric contact group, an adjustment device, and an outlet box to the structure. When the temperature changes, the pointer (moving contact) is in contact with or disconnected from the preset temperature control fixed contact (upper or lower limit), so that the relay or contactor in the control circuit is activated to achieve automatic temperature control. Or alarm function.
