The DHE-FT fork-type level switch utilizes piezoelectric devices to drive and detect the vibration of the fork; it is a highly reliable, compact control switch for level measurement. When the fork contacts the liquid being tested, its resonance frequency decreases significantly. The change in vibration frequency is reflected directly in the output signal of the piezoelectric detector, and the detection circuit identifies this frequency change and outputs a switch signal. It is widely used in industries such as petroleum, chemicals, food, and pharmaceuticals due to its efficiency, easy installation, and low maintenance requirements. The decolorizing solution section is an essential part of the production process for producing phthalamic acid, the main product of the user’s phase one project. Process engineers pay special attention to the accuracy, safety, and reliability of the control system related to the centrifugal filter in the decolorization circulation pump during production. Measurement challenges and solutions: Since the decolorization circulation pump coupled with the candle filter constitutes an important process step on-site, it is necessary to monitor the liquid condition within the pipes for interlock control purposes. Because the liquid flow rate in the pipeline is high and the pressure is high, it exerts a certain impact on the instruments ； On the other hand, due to the limited space in the pipelines and restricted installation locations, users need to pay more attention to factors such as the product’s installation and maintenance requirements sowie its service life when selecting instruments. Taking into account the actual conditions and fully considering the factors that can affect accurate measurements on site, the engineers at Dinghua Electronics recommend that users use the DHE-FT fork-type level switch, and they provide guidance on its installation on site. After using it for a period of time, users reported that the product offers precise monitoring and stable performance. Product features: Dinghua Electronics’ unique “ELL signal analysis technology” utilizes advanced intelligent processing methods to overcome the effects of interference factors such as foam, adhesion, and changes in medium composition. It is suitable for various complex field conditions and ensures long-term stable and reliable operation ； Designed to resist turbulence, splashing, foam, and vibration; it comes standard with a 316L material \"quick-drop\" type fork structure that ensures the corrosion resistance of the material in contact with liquids as well as reliable rigidity. This design improves response speed while significantly reducing the impact of viscous media sticking to the surface ； No mechanical moving parts, simple installation, and no calibration required; it can be used right away on site, significantly reducing the workload for personnel ； The DHE-FT tuning fork level switch is suitable for measuring the level in containers, storage tanks, tanks, and pipelines. It offers reliable performance and is not affected by flow rates, disturbances, bubbles, foam, vibrations, media containing solids, or adhesions. Its compact and lightweight design makes it an ideal alternative to traditional pipeline switches for monitoring liquid levels in pipelines. 1.
