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
