HCX-BW-SST Column level indicators for hot water, technopolymer


Main specifications


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.
The special technopolymer used for HCX-BW-SST column level indicator allows to use it even in circuits working with very hot water and prevents milk effect on the transparent surface.

Screws, nuts and washers

AISI 303 stainless steel screws, AISI 304 stainless steel nuts and washers.

Packing rings

FKM type VITON®*O-Ring.
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.


When fitting is not possible from the inside of the reservoir and the walls are not thick enough, the screws can be used together with Fast Mounting Kit.

Maximum continuous working temperature

80°C with peaks of 90°C.

General information

Features and performances

Ultrasound welding to guarantee a perfect seal.
Maximum fluid level visibility even from side positions.
Lens effect for a better visibility of the fluid level.

Technical data

In laboratory tests carried out with mineral oil type CB68 (according to ISO 3498) at 23°C for a limited period of time, the weld stood up to 10 bar.
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.
