差压压力变送器是测量变送器两端压力之差的变送器,输出标准信号(如 4~20mA、0~5V),用于测量液体、气体和蒸汽的液位、密度和压力等。今天我们主要来介绍一下差压压力变送器的六个操作步骤,希望可以帮助用户更好的应用产品。
Differential pressure transmitter is a transmitter to measure the pressure difference between the two ends of the transmitter, which outputs standard signals (such as 4-20mA, 0-5V) to measure the liquid level, density and pressure of liquid, gas and steam. Today we mainly introduce the six operation steps of differential pressure transmitter, hoping to help users better apply the product.
3151型法兰式多参量液位变送器的安装操作步骤 1、选择恰当的位置:当差压变送器的安装位置过于靠近生产线上游的时候,未熔融的物料就会磨损到传感器的顶部。假如传感器被安装在了太过于靠后的位置,那在传感器以及螺杆行程之间就会产生熔融物料的停滞区,熔料在那里很有可能会产生降解,压力信号也可能传递失真。一般来说,传感器可以位于滤网前面的机筒上、熔体泵的前后或者模具中
Operation steps for installation of 3151 flange type multiparameter liquid level transmitter 1. Select proper position: when the installation position of differential pressure transmitter is too close to the upstream of the production line, the unmelted material will wear to the top of the sensor. If the sensor is installed too far back, there will be a stagnation zone between the sensor and the screw stroke, where the molten material is likely to degrade, and the pressure signal may also transmit distortion. In general, the sensor can be located on the barrel in front of the filter screen, before and after the melt pump, or in the mold

Check the size of mounting hole: if the size of mounting hole is not appropriate, the thread part of differential pressure transmitter is easy to be worn during installation. This will not only directly affect the sealing of the equipment, but also make the pressure sensor unable to fully play its role, and may even produce security risks. Only a suitable mounting hole can avoid thread wear. Usually, we can use a mounting hole measuring instrument to carry out fine detection of the mounting hole to make appropriate adjustments.
3151型法兰式多参量液位变送器的安装操作步骤 3、避免低温干扰:在挤出生产过程中,如果挤出机在开始进行生产前还没有达到操作温度,那么传感器和挤出机都会受到一定程度的损坏。另外,如果传感器从冷的挤出机上被拆除,材料就可能粘附在传感器顶部引起震动膜的损坏。所以说,在拆除差压变送器之前,应确认机筒的温度足够高,机筒内部的物料处于软化状态下。

Avoid low temperature interference: in the process of extrusion production, if the extruder has not reached the operating temperature before production, the sensor and extruder will be damaged to a certain extent. In addition, if the sensor is removed from the cold extruder, the material may adhere to the top of the sensor and cause damage to the vibration film. Therefore, before removing the differential pressure transmitter, it should be confirmed that the temperature of the barrel is high enough and the materials inside the barrel are in the softened state.
3151型法兰式多参量液位变送器的安装操作步骤4、保持干燥:尽管差压变送器的电路设计是能够经得起苛刻的挤出加工环境,但是多数传感器也不能绝对防水,在潮湿的环境下也不利于正常运行。因此,需要保证挤出机机筒的水冷装置中的水不会渗漏,否则会对传感器造成不利影响。如果传感器不得不暴露在水中或潮湿的环境下,就要选择具有极强防水性的特殊传感器。

Keep dry: Although the circuit design of differential pressure transmitter can withstand harsh extrusion processing environment, most of the sensors can not be absolutely waterproof, which is not conducive to normal operation in wet environment. Therefore, it is necessary to ensure that the water in the water-cooling device of the extruder barrel will not leak, otherwise it will cause adverse effects on the sensor. If the sensor has to be exposed to water or humid environment, it is necessary to select a special sensor with strong water resistance.

Keep the installation hole clean: keep the installation hole clean is mainly to prevent the melting material from blocking, which is very important to ensure the normal operation of the equipment. Before the extruder is cleaned, all pressure sensors should be removed from the barrel to avoid damage. When the sensor is removed, the molten material may flow into the mounting hole and harden. If the residual molten material is not removed, the top of the sensor may be damaged when the sensor is installed again. The cleaner's kit is able to remove these slag residues. However, repeated cleaning may deepen the damage to the sensor caused by the mounting hole. If this happens, measures should be taken to raise the position of the sensor in the mounting hole.
3151型法兰式多参量液位变送器的安装操作步骤 6、认真全面清洁:在使用钢丝刷或特殊化合物对挤出机的机筒进行清洁之前,应该将所有的差压变送器都拆卸下来。因为这两种清洁方式都可能会造成传感器的震动膜受损。当机筒被加热时,也应该将传感器拆卸下来并使用不会产生磨损的软布来擦拭其顶部,同时传感器的孔洞也需要用清洁的钻孔机和导套清理干净。
Operation steps for installation of 3151 flange type multi parameter liquid level transmitter 6. Careful and comprehensive cleaning: all differential pressure transmitters shall be removed before cleaning the barrel of extruder with wire brush or special compound. Because both cleaning methods may damage the vibration film of the sensor. When the cylinder is heated, the sensor should also be disassembled and the top of the sensor should be wiped with a soft cloth that will not produce wear. At the same time, the holes of the sensor should also be cleaned with a clean drilling machine and guide sleeve.
