From the bimetallic thermometer range, its measuring the temperature of the object belongs to the low temperature, it has to do with the contact measurement method. If they handled roughly then calibration can be disturbed; These are not suggested for above 400’C temperature. When the temperature surroundings the strip vary, the strip bends towards the circular arc. They can with stand 50% over range in temperaures. Is a lot of food cooking suitors essential artifact. Limitations of bimetallic thermometer: They are not recommended for temperature above 400’C. Speaking of bimetallic thermometer range, due to the limitation of temperature sensing element, can generally be measured temperature range Exhibition No. This enables scale ranges of -200 to +700 °C in different class accuracies, response times and resilience to environmental influences. Where, t – the total thickness of the strip The Bi-metal thermometer is durable and has a wider temperature range then many other thermometers. However, such thermometers have a rather slow response and, by definition, require the whole of the sensing element to be immersed in the fluid whose temperature is being measured. e1265 of International Petrochemical Equipment Exhibition. The figure below shows the bimetallic strip in the form of the straight cantilever beam. The strip consists of two strips of different metals which expand at different rates as they are heated, usually steel and copper, or in some cases steel and brass. for measuring the temperature.

These thermometers are available in various dial sizes, temperature ranges, sheath diameters, sheath lengths and mounting options. They can be used where evr a mecury –in-glass thermometer is used. Red and blue pointers to indicate highest and lowest temperatures reached since reset. Fahrenheit and Celsius conversion formula: C = 5/9 ( A thermometer is a device that is used to measure the temperature of a body. Due to their metallic materials, bimetallic thermometers can be used at temperatures from below -100 °C to more than 500 °C. Offers dampening options to counter vibration. for measuring the temperature. Bimetal thermometers are ideal for local, eye-level temperature readings in most process applications. +86 13816377866    |    jimmy011@126.com, ○ Phone: +86 13816377866 The temperature coefficient shows the relation between the change in the physical dimension of metal and the temperature that causes it. Because of the thermal expansion property of metal the deformation occurs in the spring with the variation of temperature. View Tameson’s range of bimetallic thermometers. Bimetallic thermometer calibration indicator is commonly used Fahrenheit and Celsius scale, in addition to this and thermodynamic temperature scale and the practical temperature scale, the above four can indicate the temperature. F - The physical dimension of the metals varies with the variation in temperature. The portable bimetallic thermometer temperature range is much more suitable? They can be recalibrated with a turn of the calibration screw on the back of the dial. A variety of options are available for your specific process needs. Both the metals have a different temperature coefficient. Participated In The International Petrochemical Equipment Exhibition. Temperature; Bimetallic thermometers; Bimetallic thermometers. The bimetallic thermometer is used in household devices likes oven, air conditioner, and in industrial apparatus like refineries, hot wires, heater, tempering tanks etc. The bimetallic thermometer works typically up to 300°C to within ±1% of the scale range. The above said good contact specific what things? Applications of Bimetallic Thermometer. Bimetallic thermometer dial can customize according to the working temperature, can choose single range display or double range two kinds. Versions are available with up to IP68 Ingress Protection and ATEX versions are avialable for use in potentially epxplosive atmospheres. Consider the strip is fixed at one end and free to move at the other end. As a physical unit, temperature cannot be measured directly, only by means of a process involving a change in temperature. If the length of strip increases, the size of thermometer also increases. A bimetallic strip curves or twists when exposed to a temperature change, as Figure 7-2 shows, because of the different thermal expansion coefficients of the metals used in it. Vapour Pressure Thermometers SIKA SolarTemp Digital Thermometer Hand-held Infrared Thermometers Gas Expansion Thermometers Duct Mounting Thermometers General Enquiries; Office Locations; Sales; … The thermometer gives the less accurate result while measuring the low temperature. Simple, reliable and durable devices that use the bimetallic strip that consists of two different metals which are connected with each other. Selection of … Mainly used in the kitchen. ○ Add:NO999, Sunqiao RD, Pudong area, Shanghai, China. Copyright © 2019 Shanghai Jiutian Automation Equipment Co., Ltd. | All Rights Reserved. Helical Types Bimetallic Strip – The helix type bimetallic strip is mostly used for industrial applications. The Celsius scale ( Whats their characteristics? Definition of the difference between 0 degrees difference, under normal atmospheric pressure, will the freezing point of pure water as the 0 degrees Celsius, Fahrenheit will ice, water, the melting point of a mixture of ammonium chloride and sodium chloride as zero. The dial of the bi-metal thermometer then displays the temperature. REOTEMP’s Bimetallic(Bimetal) Thermometers are reliable and accurate temperature sensors requiring no electricity or wiring. For practical applications, the strip is made of metals whose moduli of elasticity and thickness are same. The radius of the arm is given by the formula shown below.The above equation shows that the strip bend towards the metals which has a low-temperature coefficient (when the temperature increases) and the inverse will happen when the temperature decreases. The thermometer gives the less accurate result while measuring the low temperature. When the temperature increases, the strip bends towards the metal which has a low-temperature coefficient. The disadvantages are. 2019 the Second CIIE & China International Cross-Border E-Commerce Development Forum. 1. The moduli of elasticity show the ability of the material to regain its original position or shape after the removal of force or load. REOTEMP’s Bimetal Thermometers are reliable and accurate temperature sensors requiring no electricity or wiring. They are simple, robust and inexpensive.
