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

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.

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.

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.

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.
