bimetallic thermometers 產(chǎn)品信息

Summary
The bimetallic thermometer is a on site measurement instrument suitable for measuring middle and high temperature, and can be used to measure directly the temperature of gasses and liquids. Compared with glass thermometer, it is featured with no mercury harmness, distinct reading, strong and durable and other advantages. Our company produces multipurpose bimetallic thermometers. The types and models are complete. The quality is high and reliable. It can be used widely in industry, agriculture, national defence and scientific research etc.
Structure features and working principle
Bimetallic thermometer (hereafter referred to as simply thermometer) is a coiling thermal bimetal temperature sensor. One end is fixed inside the protective sleeve (fixed end) and another end (free end) is connected at a fine axle. The axle end is equipped with a needle. When the temperature changes, the free end of the temperature sensor rotates, hereupon, the fine axle moves the needle. The dial plate indicates the temperature change. The steering drive mechanism in the straight meter moves the needle. The meter housing is made of steel plate, cast aluminium alloy and stainless steel. For the head of the adjustable angle thermometer, by means of corrugated pipe, angle machenism and other parts, the angle can be adjusted freely from the angle type to straight type, or from the straight type to angle type. The electric contact bimetallic thermometer is added with electrical contacts, adjusting devices, outlet box etc. When the temperature fluctuates, at the moment when the needle (moving contact) and the pre-established temperature control contact (upper limit or lower limit) are connected or disconnected, the relay or the contactor in the control circuit moves, thereby, realizing automatic temperature control or producing alarm
