Industrial Thermometer
The bimetal thermometer made in China uses a threaded thermal bimetallic sheet as a temperature sensing device, and installs it in a protective sleeve. One end is fixed, called the fixed end, and the other end is connected to a thin shaft, called free end. A pointer is mounted on the free end spool. When the temperature changes, the free end of the temperature sensing device rotates accordingly, which drives the pointer on the thin shaft to change the angle and indicates the corresponding temperature on the dial.
The Ningdian® Filled Thermometers can be installed in most existing piping and tank applications ,which are available as direct reading ,or remote reading with stainless steel bulbs and armored capillary .The sensing bulb should be placed in a none-turbulent area of piping or ducting and as close the center of the flow as possible .In tanks,it should be placed in an area of the tank that will provide a good average of the temperature of the fluid contained .The bulb should be protected from corrosive or abrasive media and excessively high pressure .The usual method of protection is the use of a thermowell.

Bimetal Thermometer
The China Ningdian® bimetal thermometer combines two metals with different linear expansion coefficients, and one end is fixed. When the temperature changes, the thermal expansion of the two metals is different, which drives the pointer to deflect to indicate the temperature. The temperature measurement range is -80~500C, which is suitable for temperature measurement when the industrial precision is not high. As a temperature sensing element, bimetal thermometer can also be used for automatic temperature control.

Adjustable Angle Bimetal Thermometer
The China Ningdian® Adjustable angle bimetal thermometer includes a versatile case and stem that can be adjusted to almost any angle for easy viewing.The head can be rotated 360º and the stem positioning moves over 180º. The Ningdian® durable adjustable angle temperature gauges are rugged and the preferred method to measure temperature in the process, offshore, power, pharmaceutical, and chemical industries. The standard union connection is 1/2-14 NPT, but others are available.

Gas Filled Thermometer
The China Ningdian® Gas Filled Thermometers are manufactured to the highest standard for a wide range of uses and may be fitted to almost any thermometer indicating appliction. Gas Filled Thermometers made in China are ideal for remote reading panel installations ,and can be provided with tube system length up to 100 feet .Being vapor actuated ,they are not subject to indicator error dut to ambient temperature variations along the tube system,and will give excellent reading both above and below ambient. Vapor instruments have progressively graduated scales and are best read in the upper of the temperature range.

Gas Filled Thermometer With Capillary
The Ningdian® gas filled thermometer with capillary is also suitable for the transmission of the measured value via capillary, due to its helium filling. Such a capillary has an outer diameter of only 2 mm and an inner diameter of 0.1 to 0.2 mm. In the reaction to a temperature change, both dial thermometer types function in accordance with the expansion principle. But the rotation of the helix in bimetal thermometers can only react directly and without “detour” on the indication.
