It can be used to directly measure the temperature of gas, liquid and steam. The thermometer is waterproof, corrosion-resistant, vibration-resistant, intuitive and easy to design. Reading, mercury-free, rugged and so on. It can replace other geotechnical temperature measuring instruments and is widely used in petroleum and chemical industry, machinery, shipbuilding, power generation, textile, printing and dyeing industries and scientific research departments.
The bimetal thermometer features no mercury damage during use and maintenance, easy to read, and rugged. The protective tube is 1Gr18Ni9Ti stainless steel and titanium molybdenum, which has strong pressure and corrosion resistance. Pull-type thermometer can be maintained or replaced for a short time without stopping the machine. Axial type, radial type, 135? Type, universal type and other varieties are complete, suitable for various site installation needs. 1. During the storage, installation, use and transportation of WSS series bimetal thermometers, try to avoid collision with the protection tube, and do not bend or deform the protection tube. During installation, it is strictly forbidden to twist the meter case. 2. The meter should work normally in the ambient temperature of -30 ℃ ～ 80 ℃. 3. The temperature at which the meter often works is preferably between 1/2 and 3/4 of the scale range.

是一种测量中低温度的现场检测仪表。 WSS series bimetal thermometer is a kind of on-site detection instrument for measuring low and medium temperature. It can directly measure the temperature of liquid vapor and gas medium in the range of -80 ℃-+ 500 ℃ in various production processes. The temperature is displayed on-site, which is intuitive, convenient, safe and reliable, and has a long service life. The core-pull thermometer can be maintained or replaced for a short time without stopping the machine. Axial type, radial type, 135o type, universal type and other varieties are complete, suitable for various site installation needs. WSSX stands for electric contact bimetal thermometer. The electric contact bimetal thermometer is based on a bimetal sheet wound in a loop shape. When one end is heated and expanded, the pointer is driven to rotate, and the working instrument displays the corresponding temperature value, and prevents environmental vibration. The bimetal thermometer is filled with silicone oil or the display part of the bimetal thermometer is separated from the measurement part to achieve the effect of shock resistance. The electric contact bimetal thermometer uses the change of temperature to drive the change of the contact. When it is disconnected with the upper or lower limit contact, the relay in the circuit is activated, so as to automatically control and alarm.
