Product Description

Overview
 
The bimetallic thermometer is an on site measurement instrument suitable for measuring middle and high temperature, and can be used to directly measure the temperature of gas and liquid. Compared with glass thermometer, it is featured with mercury harmless, distinct reading, strong and durable and other merits. 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 mechanism and other parts, the angle can be adjusted freely from the angle type to straight type, or from the straight type to angle type.
