Construction Features and Materials<\/strong><\/h3>\n

The Miselli XL \/ XLT \/ XLT-PLAST Series Vertical Level Indicator is an essential technical component for visual monitoring in modern hydraulic systems. The main body is molded using high-quality transparent polyamide resin, developed to ensure excellent mechanical performance in industrial environments. The two half-shells forming the sight glass are firmly joined \u05d1\u05d0\u05de\u05e6\u05e2\u05d5\u05ea an advanced ultrasonic welding process, ensuring long-lasting airtight sealing. Inside the transparent plastic body, there is a white lacquered aluminum plate with clear minimum and maximum level markings, facilitating visual inspection. The screws and flanged nuts supplied for installation are made of bright zinc-plated steel, ensuring a strong structural fastening.<\/p>\n

Fluid Specifications and Operating Limits<\/strong><\/h3>\n

The indicator is thoroughly tested and suitable for use with a wide range of fluids, including synthetic oils, mineral oils, diesel, and certain types of gasoline. The recommended maximum continuous operating temperature is 90\u00b0C, tested at an operating pressure of 1 bar, while the working range extends down to -30\u00b0C. It is essential to avoid direct or prolonged contact with alcohol, cleaning liquids containing alcohol-based substances, and high-temperature coolant fluids, as these may alter and compromise the mechanical integrity of the plastic material.<\/p>\n

Available Models and Variants<\/strong><\/h3>\n

The entire range is carefully structured to meet various application and environmental protection requirements:<\/p>\n

    \n
  • XL Series:<\/strong> Standard version equipped with an external protection in solid black-painted metal sheet.<\/li>\n
  • XLT Series:<\/strong> This variant integrates a capillary thermometer fixed directly onto the internal aluminum plate, with a scale of 0\u2013100\u00b0C (50\u2013200\u00b0F), allowing simultaneous monitoring of level and temperature. The specific model XL\/03T features a scale calibrated for 0\u201380\u00b0C (50\u2013150\u00b0F).<\/li>\n
  • XLT-PLAST Series:<\/strong> Features a durable external housing made of Polyamide 66, offering a lightweight alternative to traditional metal protection.<\/li>\n
  • Special Versions:<\/strong> The technical catalog includes the VL version with openings on both sides for enhanced lateral visibility; the XL-T\/CX model made of special resin resistant to alcohol-based fluids; the XL-T\/RB variant equipped with an internal red floating ball for very clear fluids; and configurations with FKM VITON\u00ae O-rings (XL-T\/V) for exceptional sealing requirements. Dimensionally, the XL\/03 model has a center distance of 76 mm and weighs 135 grams, while the XL\/05 model has a center distance of 127 mm and weighs 187 grams.<\/li>\n<\/ul>\n

    Installation, Applications and Reference Sectors<\/strong><\/h3>\n

    Installation is highly versatile for technicians. It can be performed externally on the tank by creating two M10 or M12 threaded holes, or internally using the supplied flanged nuts through through-holes ranging from 10.5 mm to 12.5 mm in diameter, ensuring no chamfers or residual burrs are present. Rear hydraulic sealing is optimally ensured by flat NBR 70 Shore gaskets and O-rings. It is strongly recommended not to exceed a maximum tightening torque of 3 Nm to prevent structural damage to the mounting points. Designed for dedicated installation on hydraulic tanks and power units, this accessory is crucial for machine safety. The use of corrosion-resistant materials, such as AISI 303 stainless steel screws available for PLAST versions, further extends its use in highly aggressive environments.<\/p>\n
