Daily maintenance 1. Check the mounting hole size: If the size of the mounting hole is inappropriate, the sensor during the installation process, which is very susceptible to wear the threaded portion. This will not only affect the sealing performance of the device, and the pressure sensor is not functioning well, and may even produce a security risk. Only the right to be able to prevent the threaded mounting holes wear (thread industry standard 1 / 2-20 UNF 2B) honeywell absolute pressure transmitter, you can usually use the mounting holes on the mounting holes measuring instrument for detecting absolute pressure transmitter intelligent to make appropriate adjustments. 2, keeping mounting holes clean: clean mounting holes and prevent clogging of the melt to ensure the normal operation of the equipment is very important. Before the extruder to be cleaned, all of the pressure sensor from the barrel should be removed to avoid damage. When removing the sensor, the melt may flow into the mounting holes and hardened, if these residual melt is not removed import absolute pressure transmitter, install the sensor again when it may cause damage to the top. These cleaning kit can melt residues removed. However, repeat cleaning process may deepen the damage caused by the mounting holes on the sensor. If this happens, we should take measures to raise the position of the sensor in the installation bore. Transmitter Maintenance 3, select the appropriate location: When installing the pressure sensor position is too close to the upper reaches of the production line, unmelted material may be worn on top of the sensor; if the sensor is mounted in a position too far back in the sensor and the screw may cause stroke stagnation region between the molten material absolute pressure transmitter, melt where possible to produce degradation, the pressure signal may be transmitted distortion; if the sensor is too deep barrel, screw may come into contact during rotation top of the sensor and cause damage. In general, the sensors can be located on the screen in front of the barrel, before and after the melt pump or mold. 4. Carefully clean; before using a wire brush or special compound extruder barrel cleaning, all sensors should be removed. Because the two cleaning methods are likely to cause vibration sensor membrane damage. When the barrel is heated, the sensor should also be removed and no wear using a soft cloth to wipe the top, while the holes of the sensor also need cleaning drill and guide clean.
