Industry Information
Shockproof thermometer is based on bimetallic sheet that is wound into a loop shape
2012-2-25 9:37:45


是基于绕制成环性弯曲状的双金属片组成。 Shockproof thermometers are based on bimetallic sheets that are wound into 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 thermometer is filled with silicone oil or the thermometer display part is separated from the measurement part to achieve the effect of shock resistance.

WSSN series shockproof thermometer is a kind of on-site measuring instrument for measuring low and medium temperature. It can directly measure the harsh and vibrating temperature of liquid, steam and gas medium in the range of -80 ℃ ~ + 500 ℃ in various production processes. This earthquake-resistant thermometer has the characteristics of waterproof, corrosion-resistant, shock-resistant, intuitive, easy to read, mercury-free, durable and so on. And other industrial and scientific sectors.

Shockproof thermometer is a kind of on-site detection instrument for measuring low and medium temperature. Shockproof thermometers can directly measure the harsh and vibrating temperature of liquid, steam and gas medium in the range of -80 ℃ ~ + 500 ℃ in various production processes. The thermometer is waterproof, corrosion-resistant, vibration-resistant, intuitive, easy to read, mercury-free, rugged and durable from the design principle and structure. It is widely used in petroleum, chemical, machinery, marine, power generation, textile, printing and dyeing industries and Scientific research department. It is an on-site measuring instrument for measuring low and medium temperatures. It can directly measure the temperature of liquid vapor and gas medium in the range of -80 ℃-+ 500 ℃ in various production processes.

Features

Display temperature on site, intuitive and convenient; safe and reliable, long service life;
A variety of structural forms can meet different requirements.
Mercury-free, easy to read, rugged and shock-resistant.
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.
The integrated types include axial, radial, and universal types, which are suitable for various site installation needs.

working principle

是基于绕制成环性弯曲状的双金属片组成。 Shockproof thermometers are based on bimetallic sheets that are wound into 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 thermometer display part is separated from the measurement part to achieve the effect of shock resistance. Shockproof thermometers are divided into two types of integrated shockproof thermometers and separate thermometers.
JB / T8803-1998 GB3836-83
Other parameters Nominal diameter of the dial: 60 100 150
Thermal response time: ≤40S
Accuracy grade: (1.0), 1.5
Angle adjustment error: The angle adjustment error should not exceed 1.0% of its range
Protection level: IP55
Hysteresis: the hysteresis thermometer hysteresis should not be greater than the absolute value of the basic error limit repeatability: the hysteresis thermometer repeatability limit range should not be greater than 1/2 of the absolute value of the basic error limit

Tips for using a shockproof thermometer:
在安装后一定要将表盘外圈最上面的橡胶堵头用剪刀剪开,以利于表腔内与外界联通,利于温度计的指针动作灵敏,测量准确。 After installation, the rubber plug at the top of the outer ring of the dial must be cut with scissors to facilitate communication between the inside of the watch cavity and the outside world, and to facilitate the sensitive pointer movement and accurate measurement.
