Description

Main specifications

Material

Transparent polyamide based (PA-T) technopolymer. Highly resistant to shocks, solvents, oils with additives, aliphatic and aromatic hydrocarbons, petrol, naphtha, phosphoric esters.Avoid contact with alcohol or detergents containing alcohol.

Protection frame

Glass-fibre reinforced polyamide (PA) SUPER-technopolymer, black colour, matte finish. Supplied assembled, removable by a screwdriver.

Screws

Glass-fibre reinforced polyamide (PA) SUPER-technopolymer, lightweight and high mechanical strength.Anticorrosive material: suitable even in the presence of liquid or humidity.Resistant to several washing cycles with solvents and detergents, for this reason it is suitable for applications in the pharmaceutical or food industry.

Nuts and washers

AISI 304 stainless steel.

Packing rings

Step-shaped for the seal on the reservoir walls and NBR synthetic rubber O-ring screw underhead.
Suggested roughness of the packing ring application surface Ra = 3 µm.

Contrast screen

White lacquered aluminium. The housing, in the appropriate external rear slot, guarantees the best protection from direct contact with fluid.It can be taken out from the inclined side, before assembly to allow the insertion of level lines or words.

Standard executions

  • HCZ-VT: without thermometer and without protection frame.
  • HCZ/T-VT: with thermometer incorporated, without protection frame.
  • HCZ-P-VT: without thermometer, with protection frame.
  • HCZ/T-P-VT: with thermometer incorporated and protection frame.

Maximum continuous working temperature

90°C (with oil).

General information

Features and performances

Thanks to the SUPER-technopolymer screws, HCZ-VT column level indicator can be used in corrosion resistance applications where stainless steel is not necessary.The special slotted head of the SUPER-technopolymer screws is especially designed to reach an optimum tightening of the packing rings by applying an adequate tightening torque (ELESA patent) thus avoiding unnecessary stress to the screws.Ultrasound welding to guarantee a perfect seal.Lens effect for a better visibility of the fluid level and temperature.Special openings in the protection frame provide maximum fluid level visibility even from side positions.All shocks are absorbed by the frame that transmits them directly onto the wall of the reservoir.

Technical data

Considering the SUPER-technopolymer screws, the maximum working pressure cannot be higher than 5 bar at 20°C and 2 bar at 90°C.For higher pressure values use HCZ-SST with stainless steel screws.For use with other fluids and under different pressure and temperature conditions, please contact ELESA Technical Department.In any case we suggest to verify the suitability of the product under the actual working conditions.
