3151静压式投入式液位变送器的调校/投入式液位变送器安装后该怎样维护
        (1)在流动介质和波动较大的介质中,安装投人式平衡罩时,要附加熏锤(大于5kg)或固定在固体上,必要时应加防波管。被测量液体底部若有沉淀物,变送器平衡罩应提高,或加以过滤保护,以免堵塞。
        (2)变送器量程可降低使用,但不准超量程上限使用。
        (3)为防电磁辐射与雷电袭击应将变送,器外壳接地采用屏蔽电缆或埋设地下电缆。
        (4)使用一段时间后如发现误差较大时,可把变送器的平衡罩拉出介质,串人电流表后调整零点电流应为4mA,调整后再插人介质中。
        (5)安装在敞开池或罐时可吊装,变送器挂扳用M8螺栓固定,防腐容器一般用法兰安装。
        (6)出厂时,零点(大气压时)为4mA,满量程20mA已调好,请勿动。
        (7)导气管不得损伤漏进被测介质或漏气,否则不能正常使用。
        (8)在爆炸环境使用时,要选用专为防爆而设计的变送器意识别防爆类型的标志。可供选用WMY-A-EX系列.
        (9)为避开现场腐蚀性气体,根据脱离距离,让中继箱及传感器不被腐蚀,可适当加长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
