3151靜壓式投入式液位變送器的調(diào)校/投入式液位變送器安裝后該怎樣維護(hù)
（1）在流動介質(zhì)和波動較大的介質(zhì)中，安裝投人式平衡罩時，要附加熏錘(大于5kg)或固定在固體上，必要時應(yīng)加防波管。被測量液體底部若有沉淀物，變送器平衡罩應(yīng)提高，或加以過濾保護(hù)，以免堵塞。
（2）變送器量程可降低使用，但不準(zhǔn)超量程上限使用。
（3）為防電磁輻射與雷電襲擊應(yīng)將變送，器外殼接地采用屏蔽電纜或埋設(shè)地下電纜。
（4）使用一段時間后如發(fā)現(xiàn)誤差較大時，可把變送器的平衡罩拉出介質(zhì)，串人電流表后調(diào)整零點電流應(yīng)為4mA，調(diào)整后再插人介質(zhì)中。
（5）安裝在敞開池或罐時可吊裝，變送器掛扳用M8螺栓固定，防腐容器一般用法蘭安裝。
（6）出廠時，零點(大氣壓時)為4mA，滿量程20mA已調(diào)好，請勿動。
（7）導(dǎo)氣管不得損傷漏進(jìn)被測介質(zhì)或漏氣，否則不能正常使用。
（8）在爆炸環(huán)境使用時，要選用專為防爆而設(shè)計的變送器意識別防爆類型的標(biāo)志。可供選用WMY-A-EX系列.
（9）為避開現(xiàn)場腐蝕性氣體，根據(jù)脫離距離，讓中繼箱及傳感器不被腐蝕，可適當(dāng)加長L2

151 liquid level transmitter is independent as the core circuit board and sensor technology based on the northwest. In the view of Xi'an liquid level transmitter manufacturer, input liquid level transmitter is widely used in municipal life, chemical processing, petrochemical production and other industries. Xi'an Huaheng instrument manufacturer provides it to many manufacturers in design and use, Static pressure liquid level transmitter with strong economic applicability, high stability in complex working conditions and good universality
Adjustment / maintenance of 3151 static pressure input liquid level transmitter
(1) In the flowing medium and the medium with large fluctuation, when installing the throw type balance cover, it is necessary to attach a fuming hammer (more than 5kg) or fix it on the solid. If necessary, it is necessary to add a wave tube. If there is sediment at the bottom of the measured liquid, the balance cover of the transmitter shall be raised or filtered to avoid blocking.
(2) The transmitter range can be reduced, but it is not allowed to exceed the upper range.
(3) In order to prevent electromagnetic radiation and lightning attack, the transformer shall be sent, and the shield cable or buried underground cable shall be used for the grounding of the device shell.
(4) after a period of time, if the error is large, the balance cover of the transmitter can be pulled out of the medium. After adjusting the current meter, the zero current should be adjusted to 4mA and then inserted into the medium.
(5) When it is installed in the open pool or tank, it can be hoisted, the transmitter hanging plate is fixed with M8 bolts, and the anti-corrosion vessel is generally installed with flange.
(6) When leaving the factory, the zero point (at atmospheric pressure) is 4mA, and the full range 20mA has been adjusted. Do not move.
(7) The airway shall not be damaged or leak into the tested medium or air, otherwise it cannot be used normally.
(8) When used in explosion-proof environment, the transmitter designed for explosion-proof shall be selected to identify the explosion-proof type. Wmy-a-ex series is available
(9) In order to avoid corrosive gas on site, L2 can be lengthened appropriately according to the separation distance to prevent the trunk and sensor from corrosion
Huaheng transmitter manufacturers have developed two core technologies, sensor and intelligent circuit board. Not only do they master all the core component technologies of all products, but also the accuracy of industrial automatic transmitter manufacturers is constantly improving, from level 0.2 to level 0.1. Through the extension of the core technology, other products for measuring flow and temperature can be deformed.
At present, our company has three technical strength, one is the fully isolated intelligent circuit processing unit technology, the other is the manufacturing technology of metal capacitance sensor, and the third is the multi parameter technology of the whole series of throttling devices.
With its own sensor and intelligent circuit board core technology, Huaheng transmitter manufacturers can extend and transform the core technology at low cost according to customer requirements to achieve personalized product customization. The main products are smart (SMART) series pressure transmitter, multi parameter transmitter, flowmeter, temperature sensor and level (liquid level transmitter manufacturer, which provides high performance price ratio industrial automatic transmitter manufacturer products for China's power, petroleum, chemical, metallurgical, cement, mining and other industries
