Melt Pressure Sensor Placement
Some factors to consider for correct placement of the melt pressure sensor
Correct placement of the melt pressure sensor is important for accurate and reliable measurements. Here are some factors to consider for correct placement of the melt pressure sensor:
Flow Direction:
Determine the flow direction of the melt at the point where the sensor will be placed. The sensor should be placed in the area where the flow is most intense. Avoid areas with rapid or sudden changes in flow.
Distance:
Place the sensor as close as possible to the measurement point. The distance is important to minimize the effect of the melt on the measured pressure value. If a long hose must be used, choose a large diameter hose to minimize the pressure drop.
Measuring Range:
Place according to the measuring range of the sensor. The sensor must remain within the pressure range to be measured. When used outside the measuring range, measurement accuracy may be affected.
Environmental Effects:
Position the sensor so that it is not exposed to environmental influences. It is important that the sensor is not exposed to physical damage, chemicals or high temperatures. Protect the sensor from environmental influences by using a suitable protective coating or enclosure.
Mounting Surface:
Place the sensor on a smooth mounting surface. The mounting surface must ensure stable and secure placement of the sensor. It is important for the sensor to make good contact with the mounting surface for accurate measurement.
Air Bubbles:
When placing the sensor, be careful not to allow air bubbles to enter the sensor. Air bubbles can affect measurement accuracy. Minimize air bubbles by using an appropriate mounting method when placing the sensor.
Calibration:
In order for the sensor to be able to make accurate measurements, it must be calibrated periodically. Calibration ensures that the sensor functions correctly and optimizes measurement accuracy.
