    Description


    WSS-511 Φ150mm Dial Diameter Radial Installation Bimetal thermometer is a field measuring instrument for measuring medium and low temperatures. WSS-511 Bimetal thermometer is made of two kinds of metals with different temperature expansion coefficients, and is made into a heat conduction sensor, which fully utilizes the principle of thermal expansion and contraction. When the temperature of the multilayer metal sheet changes, the metal expands or shrinks in different layers, so that the spiral The roll is rolled up or loosened, as one end of the spiral is fixed and the other end is connected to a freely rotatable hand.

    Therefore, when the bimetal feels the temperature change, the pointer can indicate the temperature on a circular indexing scale. The temperature range of the bimetal thermometer is -40~550°C, and the tolerance is ±1.6 degrees. . This creates the following two misunderstandings:

    1, high temperature range

    The temperature range of the bimetal thermometer is 200~650°C (Baidu Encyclopedia is also clearly recorded), and the allowable error is about 1% of the scale range. In fact, this is not true, because this kind of metal sheet is made into a spiral coil shape heat conduction sensor, which is easy to fatigue at a high temperature of 650 ° C, and the temperature difference is very large, so when the temperature exceeds 550 ° C, thermocouple should be considered to solve this problem. problem.

    2, the lowest temperature range

    The bimetal thermometer has a temperature range of 200 to 650 ° C (this is incorrect) and the lowest temperature can be measured at -40 ° C. In fact, this is not much, because the bimetal thermometer is usually -20 °C in the production temperature (if low temperature is required, if not needed, we usually mark 0 °C to the upper limit of the customer's temperature, in the Beijing area Users sometimes use -40 ° C, this can be done, but in the case of -40 ° C, consider whether you can accept the error.
