How to maintain the mill pressure sensor

Whatever the instrument used in a long time, the life expectancy would decline . Mill pressure sensor is no exception. Pressure sensors are very important element , which is detected when the mill rolling force , it is critical components. It is mounted on the roll , and each has one side . On the steel sheet surface by measuring the total pressure force, the detected differential pressure can truly reflect the fact on the steel sheet surface uniformity of the pressure . Because it is mounted under the roll , and the environment in which it has always been very strong vibration , humidity is very high and the temperature is high. Therefore, to maintain it becomes a very difficult thing , but expensive. Therefore, how well and how to maintain the reserve sensor is especially important parts .Crankshaft Positioning Sensor installation has the following technical requirements: the sensor should be installed in the roll head below the base , the above is of ninety millimeters thick are plate , and on top of it is on a 60 mm thick plate , the following part is the next fifteen millimeters thick pad . In fact , over Car Temperature Sensor plate with the following , both the base plate and the distance between the circumference of 1.5 mm. And there is a convex bottom base , which is embedded into the mill base inside . Both upper and lower pads, and the quality of some of the requirements of the platen . Heat treatment Hardness : HB320-360. Surface roughness of 1.6um; flatness 0.05mm; parallel is 0.05 .
