Melt Pressure Sensor Installation Instructions
The diaphragm of the sensor is the most vulnerable part. Do not drop the protective cover before installation.
1. Sensor Installation
The diaphragm of the sensor is the most vulnerable part. Do not drop the protective cover before installation, meanwhile pay attention to protect the diaphragm of the sensor during installation. The machining of the mounting hole should be processed according to the technical requirements of the mounting hole size chart and size chart to avoid the normal operation of the sensor due to film scratches caused by the non-standard mounting hole.
2. Removing the Sensor
During installation, make sure that no metal foreign objects or plastic are left in the correct mounting holes. Before cleaning the extruder, remove all sensors from the machine. The sensor can only be removed while the polymer is hot melt. Wipe the sensor probe diaphragm with a soft cloth immediately after removal. At the same time, Sand Industry can provide special cleaning tools for the installation holes to remove material from the holes for the next installation.
3. About getting started
Before operating the machine, make sure there is sufficient heating and melting time to ensure that all materials in the sensor diaphragm area melt before the extruder starts working.
4. Installation Site
The probe part of the sensor can withstand high temperature, and the outer casing can withstand temperature below 80 ° C. Therefore, care must be taken to fix the attached sensor body part to room temperature during assembly and use. The isolation of the enclosure from the high temperature area helps to increase the measurement accuracy and service life of the sensor.
5.Overload Effects
In actual pressure control operation, it is better to be within nominal pressure. Although the sensor has a certain overload capacity, when prolonged overload will affect the measurement accuracy and service life of the sensor.
6. Electrical Connection of the Sensor
During the electrical connection process, the signal output connection cable of the sensor must be connected separately within the wiring harness to prevent interference in the field.
