Pressure type thermometer and temperature controller in the application of industrial washing machine what's the difference?

In the washing machine and use the thermometer? This rarely heard in your life well, but it is very common in the industry, industrial washing machinery according to the different heating mode can be divided into: general type steam type and electric heating. Whether industrial washing machine, or wrinkles in drying machine, are the two heating mode. For temperature detection, automatic industrial washing machine is commonly used temperature sensor, and the transmission of data to the control computer, and then through the computer screen display panel, type electric heating and steam are made the same way, while the dryer and ironing machine, steam and electric heating type is different, generally USES pressure type thermometer and temperature controller, what is the difference between the two? Pressure type thermometer mainly used in washing machines in the steam dryer or ironing machine. Pressure type thermometer and ordinary mercury thermometer the distinction that having essence, pressure type thermometer temperature measuring device has a temperature sensor, realized the function of mechanical and electrical integration. Pressure type thermometer inside the dryer closed inner barrel or iron machine drying cylinder, based on the relationship between temperature and saturated steam pressure, and thus for the temperature measurement. When bulb feel temperature, saturated vapor produced the corresponding pressure in the closed system, cause the change of curvature elastic element, make its produce a shift in the free end, again by the displacement amplification mechanism of gear into the indicated value, the pressure type dryer temperature measurement sensitivity, fast response. Pressure dryer is in addition to the application in industrial laundry equipment, can also be used for machinery, textile, chemical, pharmaceutical, food industry for the temperature measurement and control in the process of production. Temperature controller is composed of digital display device and temperature probe, in industrial laundry equipment, commonly used in the electric heating type dryer and ironing machine, it's different from the thermometer, it is not by the number of pressure and temperature, and direct is temperature probe temperature, repass PID feedback adjustment, the temperature directly converted into numerical display in the display. Pressure type thermometer has become more and more popular, in industrial washing machine, semi-automatic some manufacturer may use a pressure type thermometer. Special attention is that at the time of service department for repair, some customers for not understanding the difference between the two, so, after have the above understanding, at the time of maintenance, could lead to a lot of convenience for after-sale!
