Overview: The document provides technical specifications and details for HCL column level indicators with U-shaped protections, manufactured by Elesa. These indicators are designed for use in hydraulic systems and are available in various sizes.
Specifications:- Materials: The transparent tube is made of acrylic material with a lenticular effect. The protection is made of natural-colored aluminum, capable of being turned by 190°F (90°C). Assembly ends are constructed from glass-fiber reinforced polyamide-based technopolymer in black color. Screws are zinc-plated steel with a hexagon socket, and the packing ring is made of NBR synthetic rubber O-Ring. The graduated contrast screen is made of plastic material resistant to oils and greases.
- Temperature and Pressure: The maximum continuous working temperature is 160°F (70°C) with oil or water. Laboratory tests with mineral oil (CB68) at 73°F (23°C) showed the following pressure resistance: HCL.300 at 30 bar, HCL.400 at 25 bar, and HCL.500 at 20 bar.
Dimensions and Weight:- HCL-300-M12: Length 300 mm, Weight 227 g
- HCL-400-M12: Length 400 mm, Weight 268 g
- HCL-500-M12: Length 500 mm, Weight 306 g
Installation: The maximum tightening torque for all models is 15 ft·lbf (20 Nm). Drilling and installation data specify a diameter of 0.49 inches (12.5 mm).
Special Executions on Request: Options include different materials for tubes and fixing endings, AISI 316 stainless steel screws, polyamide-based technopolymer floats, and various configurations for level sensors and packing rings.
Recommendations: It is advised to verify the product's suitability under actual working conditions, especially when using different oils or fluids and under varying pressure and temperature conditions. For specific requirements, contact the ELESA Technical Department.
