訂購注意事項

PT124高溫熔體壓力傳感器安裝時注意事項

為盡量延長傳感器的使用壽命，提高使用精度，用戶在收到傳感器后或儀表后，除認真閱讀使用說明書外，注意以下六點是保證傳感器正常使用的重要因素。

1、傳感器的安裝
最易損壞壓力傳感器因素之一是安裝在不適當(dāng)?shù)目變?nèi)，孔太小或太偏，傳感器膜片被擦傷從而影響測試精度甚至完全失效。我廠能提供安裝孔加工工具，協(xié)助加工出最合適的安裝孔。

2、安裝孔的清理
當(dāng)安裝孔經(jīng)過正確加工后，最重要的是保證孔內(nèi)沒有儲存的金屬異物或塑料。在清理擠出機前將所有的傳感器從設(shè)備上卸下，以免損壞膜片，在第二次裝機前，應(yīng)用清理工具將安裝孔清理干凈。
3、不正確安裝
如果傳感器被安裝在離料口太近的地方，未熔化的塑膠或化纖顆粒會損傷傳感器的膜片，如果傳感器插入過淺，在膜片和螺桿之間形成一個堆積未熔化的膠料，長時間會碳化，影響準確地測量壓力，但插入太深會打壞膜片。

4、冷啟動
傳感器裝機后必須有足夠的加熱時間，保證物料進入螺桿內(nèi)部可變?yōu)檫m當(dāng)?shù)牧黧w，在卸下時了應(yīng)保證螺桿是在正常的工作溫度下進行，否則易損壞傳感器及設(shè)備。

5、傳感器的安裝位置
傳感器探頭耐溫450℃，外殼部份80℃，在設(shè)計安裝孔時應(yīng)考慮將傳感器盡可能安裝在主機的下部或側(cè)部，安裝好后應(yīng)檢查傳感器外殼是否在保溫層上或加熱塊上，應(yīng)盡可能離開溫度區(qū)用支架將傳感器固定。

6、過載的影響
傳感器雖然有1.5-2倍額定壓力的過載能力，但長時間過載會影響傳感的使用壽命，使用傳感器在額定壓力的0.5 - 0.8倍即可。

Precautions for installation of PT124 high temperature melt pressure sensor

In order to prolong the service life of the sensor as far as possible and improve the use accuracy, the user should pay attention to the following six points after receiving the sensor or the instrument, in addition to carefully reading the instruction manual.

1. Sensor installation
One of the most easily damaged factors of the pressure sensor is that it is installed in an inappropriate hole. If the hole is too small or too partial, the sensor diaphragm will be scratched, which will affect the test accuracy and even completely fail. Our factory can provide installation hole processing tools to help process the most suitable installation hole.

2. Cleaning of mounting holes
When the mounting hole is properly machined, it is most important to ensure that there is no metal foreign matter or plastic stored in the hole. Before cleaning the extruder, remove all sensors from the equipment to avoid damaging the diaphragm. Before the second installation, clean the mounting holes with cleaning tools.

3. Incorrect installation
If the sensor is installed too close to the material mouth, the unmelted plastic or chemical fiber particles will damage the diaphragm of the sensor. If the sensor is inserted too shallow, a deposit of unmelted rubber will be formed between the diaphragm and the screw, which will carbonize for a long time and affect the accurate measurement of pressure force. However, if the sensor is inserted too deep, the diaphragm will be damaged.

4. Cold start
After the sensor is installed, there must be enough heating time to ensure that the material enters into the screw and can be changed into appropriate fluid. When the sensor is unloaded, it should be ensured that the screw is carried out at normal working temperature, otherwise the sensor and equipment are easy to be damaged.

5. Installation position of sensor
The temperature resistance of the sensor probe is 450 ℃ and the shell part is 80 ℃. In the design of the mounting hole, the sensor should be installed at the lower part or side of the host as much as possible. After installation, the sensor shell should be checked whether it is on the insulation layer or heating block, and the sensor should be fixed with a bracket as far as possible away from the temperature area.

6. Effect of overload
Although the sensor has an overload capacity of 1.5-2 times of the rated pressure, long-term overload will affect the service life of the sensor. The sensor can be used at 0.5-0.8 times of the rated pressure.
