Company: 安徽天蒙仪表集团有限公司

Product Description: The electric displacer level gauge is a level measurement instrument designed based on Archimedes' principle and magnetic coupling technology. It can be used to measure liquid level, interface level, and density, and can be equipped with upper and lower limit alarm signal outputs. The product features a robust structure, integrated electromechanical design, and comes with an external measuring cylinder and flanges (chemical standards, petroleum standards, and other national standards). It is easy to install, capable of measuring various conductive media, suitable for diverse measurement requirements, and offers custom design for special applications. The product has the following characteristics: 1. High practicality and simple operation: Analog circuits have interdependent zero and span adjustments, requiring multiple calibrations; the smart circuit uses button settings and one-key calibration, making operation extremely simple and accurate. 2. Stable display: Analog circuits struggle to achieve significant damping and sampling times, causing instability in monitoring instrument displays during production when gas volume fluctuates slightly or the liquid level shifts minimally, leading to visual fatigue for operators; the smart level gauge employs digital software filtering technology, unaffected by gas volume or liquid level fluctuations, enabling quick tracking of transient changes while displaying the average effect of the liquid level, ensuring stable and accurate readings. 3. Wide operating range: Analog circuits, limited by hardware, require higher operating voltages, typically above 14V. When paired with safety barriers with low current, a slightly high liquid level can cause voltage drops, leading to abnormal displays and potentially misleading operators or causing accidents; the smart level gauge operates normally within 8-30V, compatible with any type of safety barrier. 4. Strong anti-interference capability: Most analog circuits, when directly connected to microcomputer systems, are affected by signals from other equipment, resulting in instability or even failure to operate; the smart level gauge uses software and hardware anti-interference and error correction technologies, allowing direct networking in non-explosive environments without isolation, reducing circuit complexity and costs. 5. Powerful functionality: On-site LCD display shows current value, percentage, or ambient temperature, equipped with various communication and debugging interfaces. 6. High accuracy and strong versatility: Intelligent temperature compensation and linear correction, automatic linear and span tracking, suitable for applications requiring high precision and stability. Technical parameters: 1. Measuring range: 0–4500mm (custom orders available) 2. Working pressure: -0.1MPa to +10MPa 3. Ambient temperature: -70°C to +80°C 4. Medium temperature: -70°C to +250°C 5.

In terms of seals, Yongxin offers hydraulic and pneumatic sealing products, including dynamic seals, static seals, sealing rings, oil seals, gaskets, packing, etc.Material Introduction:Teflon FEP and Teflon PFA are essentially similar materials, but Teflon PFA has better high-temperature resistance than Teflon FEP.Applicable Temperature Range:Teflon FEP shell: -60℃~205℃, can be used at high temperatures up to 260℃ for short periods.Teflon PFA shell: -60℃~260℃, can be used at high temperatures up to 300℃ for short periods.Solid Chem-Ring seals are widely used in both static and dynamic sealing applications. Hollow silicone rubber Chem-Ring seals generally have a larger wire diameter and are used in static sealing, with lower hardness and compression resistance compared to solid Chem-Ring seals.Hardness Introduction:The average hardness of Chem-Ring seals made from different materials is:Solid silicone rubber: 85-90Solid Viton rubber: 90-95Hollow silicone rubber: 75-80Installation Instructions for Coated Rings:1. The area where the Chem-Ring seal is installed or passed through must be smooth, free of burrs, grooves, and sharp edges. The surface finish of the inner hole should be 20 microinches, and the shaft finish should be 10 microinches.2. Lubricate the surface of the Chem-Ring seal and the relevant contact areas with clean light oil or grease.3. If installing the Chem-Ring seal on a shaft is difficult, immerse it in hot water for a few minutes to allow it to expand. This softened and expanded O-ring is easier to install. Install the O-ring while it is warm; it will return to its original size upon cooling.4. Do not bend the Chem-Ring O-ring too sharply, as this may cause Teflon to wrinkle and affect performance.Required Compression for Coated Rings:Static sealing: 15%-20%Dynamic sealing: 10%-12%Pneumatic sealing: 7%-8%Thickness of the outer coating layer (as shown in the table below)Wire diameter (inchs/mm)Thickness of outer FEP layer (inchs/mm)Wire diameter (inchs/mm)Thickness of outer FEP layer (inchs/mm)After-Sales Service:Yongxin Seals provides material certifications for all products, ensuring customers can buy and use with confidence and without worries!

Product Description: Soil moisturizer is a synthetic polymer with super absorbent and water-retaining release capabilities. It can rapidly absorb deionized water hundreds of times its own weight and tens to hundreds of times its weight in saline water. It creates a "mini-reservoir" that quickly absorbs, stores, and slowly releases water and nutrients, effectively reducing the leakage of irrigation water (or rainwater) and controlling soil moisture evaporation to meet plant growth needs, promote root development, and improve soil structure, increase soil activity, and reduce soil compaction.Product Features1. Safe and environmentally friendly, odorless, non-polluting to plants, soil, and groundwater. Suitable for fruit trees, flowers, afforestation, soilless cultivation, plant preservation and transportation, field crops, etc. The final decomposition products of soil water-retaining agent and soil erosion control agent are water, ammonium nitrogen, and sodium or potassium ions, with no residues.2. Moisture retention and water saving. Effectively inhibits water evaporation and prevents soil erosion. Even under irrigation conditions, it can save more than 50% of water.3. Improves soil structure. Amends heavy clay soils, sandy soils that leak water and fertilizer, and secondary saline-alkali soils. Promotes soil microbial development and enhances the turnover efficiency of soil organic matter.4. Long service life. Combines the characteristics of various polymers, allowing repeated water absorption and expansion as well as release and contraction. The service life in production can exceed 3 years, making it one of the longest-lasting soil moisturizing products on the market.5. Fast water absorption. Generally, natural water absorption to saturation takes about 15-40 minutes, with the fastest time being 0.4 minutes.6. High water and fertilizer utilization efficiency. The "mini-reservoir" formed by the soil water-retaining agent in the soil reduces the leaching loss of trace elements by one-third during fertilization and irrigation (or rainfall), protecting the environment. During drought, the water-saturated agent keeps the surrounding soil moist to supply water to plant roots. Even in desert areas and extreme arid climates, it enables grass planting and afforestation with an annual rainfall of 200mm.7. Water storage without root rot. The water-saturated agent molecules expand, and even when in close contact with plant roots, they do not cause root rot.8. Stable performance. Even under extreme drought conditions, it does not draw moisture from plants. more>
