thermometer factory co. , LTD. Is a professional research and development, production and sales of ultrasonic thermometer manufacturers. Ultrasonic thermometer by emitting high-energy ultrasound. To enhance the effective signals, from appearance reflected object to be tested. Reflected signals improved algorithm. Better abandoned the invalid interference signal. So, in the choose and buy ultrasonic thermometer, need according to the environmental requirements for model selection. When the instrument using environment is relatively good and just collected relevant data, generally choose a size is ok, without the second field is displayed. When the use of the instrument conditions, such as environmental humidity, ventilation, dust and the transmission distance is small, can choose separation close type. When the measured liquid, corrosive, can choose fission nearly anticorrosive thermometer.

ultrasonic thermometer level switch is used to test whether level reaches a predetermined height, and a corresponding signal switch quantity. According to different objects being measured, level switch has a variety of forms, can measure liquid level, material level, the solid-liquid interface, and judge the material in the presence of. The characteristics of material level switch is simple, reliable and easy to use, wide application scope. Using the total reflection principle also can be made into switch optical fiber liquid level detector. Fiber optic liquid level sensor consists of led light source, photoelectric diode and multimode fiber, etc. Usually at the top of the optical fiber probe is equipped with the cone reflector, when the probe did not contact, light return to photodiode on total reflection occurs in the cone. After the probe contact surface, there will be a part of the light into the liquid, and returns the photodiode intensity weaken. Therefore, when light return to mutations in the light intensity show that measuring head has been in contact with liquid level, thereby liquid level signal is given.

when choosing ultrasonic thermometer, if there are problems of unclear, or the use of instruments environment don't understand, also don't blindly use, in order to avoid damage to instrument, best consulting website: http://www. 517席。 com/chaosb/
