差壓壓力變送器是測(cè)量變送器兩端壓力之差的變送器，輸出標(biāo)準(zhǔn)信號(hào)(如 4~20mA、0~5V)，用于測(cè)量液體、氣體和蒸汽的液位、密度和壓力等。今天我們主要來(lái)介紹一下差壓壓力變送器的六個(gè)操作步驟，希望可以幫助用戶更好的應(yīng)用產(chǎn)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型法蘭式多參量液位變送器的安裝操作步驟 1、選擇恰當(dāng)?shù)奈恢茫寒?dāng)差壓變送器的安裝位置過(guò)于靠近生產(chǎn)線上游的時(shí)候，未熔融的物料就會(huì)磨損到傳感器的頂部。假如傳感器被安裝在了太過(guò)于靠后的位置，那在傳感器以及螺桿行程之間就會(huì)產(chǎn)生熔融物料的停滯區(qū)，熔料在那里很有可能會(huì)產(chǎn)生降解，壓力信號(hào)也可能傳遞失真。一般來(lái)說(shuō)，傳感器可以位于濾網(wǎng)前面的機(jī)筒上、熔體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
3151型法蘭式多參量液位變送器的安裝操作步驟 2、檢查安裝孔尺寸的大?。杭偃绨惭b孔的尺寸大小不合適，差壓變送器在安裝的過(guò)程中，螺紋部分就比較容易受到一定的磨損。這樣不但會(huì)直接影響到設(shè)備的密封性，同時(shí)還會(huì)使壓力傳感器無(wú)法充分的發(fā)揮作用，甚至有可能會(huì)產(chǎn)生安全隱患。只有合適的安裝孔才能夠避免螺紋的磨損，通常我們可以采用安裝孔測(cè)量?jī)x對(duì)安裝孔進(jìn)行精細(xì)的檢測(cè)，以做出適當(dāng)?shù)恼{(diào)整。
Operation steps for installation of 3151 flange type multi parameter liquid level transmitter 2. 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型法蘭式多參量液位變送器的安裝操作步驟 3、避免低溫干擾：在擠出生產(chǎn)過(guò)程中，如果擠出機(jī)在開(kāi)始進(jìn)行生產(chǎn)前還沒(méi)有達(dá)到操作溫度，那么傳感器和擠出機(jī)都會(huì)受到一定程度的損壞。另外，如果傳感器從冷的擠出機(jī)上被拆除，材料就可能粘附在傳感器頂部引起震動(dòng)膜的損壞。所以說(shuō)，在拆除差壓變送器之前，應(yīng)確認(rèn)機(jī)筒的溫度足夠高，機(jī)筒內(nèi)部的物料處于軟化狀態(tài)下。
Installation and operation steps of 3151 flange multi parameter liquid level transmitter 3. 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型法蘭式多參量液位變送器的安裝操作步驟4、保持干燥：盡管差壓變送器的電路設(shè)計(jì)是能夠經(jīng)得起苛刻的擠出加工環(huán)境，但是多數(shù)傳感器也不能絕對(duì)防水，在潮濕的環(huán)境下也不利于正常運(yùn)行。因此，需要保證擠出機(jī)機(jī)筒的水冷裝置中的水不會(huì)滲漏，否則會(huì)對(duì)傳感器造成不利影響。如果傳感器不得不暴露在水中或潮濕的環(huán)境下，就要選擇具有極強(qiáng)防水性的特殊傳感器。

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.
3151型法蘭式多參量液位變送器的安裝操作步驟 5、要保持安裝孔的清潔：保持安裝孔的清潔主要還是為了防止熔料堵塞，對(duì)于保證設(shè)備的正常運(yùn)行是極為重要的。在擠出機(jī)被清潔之前，所有的壓力傳感器都應(yīng)該從機(jī)筒上拆除以避免損壞。在拆除傳感器時(shí)，熔料有可能流入到安裝孔中并硬化，如果這些殘余的熔料沒(méi)有被去除，當(dāng)再次安裝傳感器時(shí)就可能造成其頂部受損。清潔工具包能夠?qū)⑦@些熔料殘余物去除。然而，重復(fù)的清潔過(guò)程有可能加深安裝孔對(duì)傳感器造成的損壞。如果這種情況發(fā)生，就應(yīng)當(dāng)采取措施來(lái)升高傳感器在安裝孔中的位置。

The installation procedure of 3151 flange type multiparameter liquid level transmitter 5. 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型法蘭式多參量液位變送器的安裝操作步驟 6、認(rèn)真全面清潔：在使用鋼絲刷或特殊化合物對(duì)擠出機(jī)的機(jī)筒進(jìn)行清潔之前，應(yīng)該將所有的差壓變送器都拆卸下來(lái)。因?yàn)檫@兩種清潔方式都可能會(huì)造成傳感器的震動(dòng)膜受損。當(dāng)機(jī)筒被加熱時(shí)，也應(yīng)該將傳感器拆卸下來(lái)并使用不會(huì)產(chǎn)生磨損的軟布來(lái)擦拭其頂部，同時(shí)傳感器的孔洞也需要用清潔的鉆孔機(jī)和導(dǎo)套清理干凈。
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.
