Additional information

Connector

Right side output including protection against water sprays (protection class IP 65 according to IEC 529 table).

Contrast screen

Aluminium. The housing, in the appropriate external rear slot, guarantees the best protection from direct contact with fluid, avoiding yellowing effect due to the prolonged action of the fluid at high temperatures.

Float

Polyamide based (PA) technopolymer, red colour, with a built-in magnetic element to activate the electric contact when the oil level drops to a minimum, set at 40mm over the screw axis (dimension l).

Material

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

MAX temperature electrical sensor (80°)

With electrical contact normally open (N.A.) or normally closed (N.C.), it is set at a standard intervention temperature of 80°C, next to a metallic plate which serves as a conductor of the heat of the fluid for a faster transmission and a lower dissipation. The inside of the cavity where the sensor is contained is completely resinated in order to increase the insulation.

Maximum continuous working temperature

80°C (with oil).

MIN level electrical sensor

With electrical contacts normally open (N.A.) or normally closed (N.C.), it generates an electric signal when the oil level reaches the minimum level. <BR>The inside of the cavity where the sensor is contained is completely resinated in order to increase the insulation.

Packing ring

NBR synthetic rubber O-Ring.

Screw-covers

Polyamide based technopolymer, grey colour.

Screws

Nickel-plated brass with hexagon socket.

Special executions on request (For sufficient quantities)

– Column level indicators in different materials (POLYCARBONATE), for use with special fluids and/or at high temperatures. <BR>- AISI 316 stainless steel or nickel-plated brass screws. <BR>- Column level indicators with change-over electrical contact. <BR>- Execution with PT100 temperature electrical probe for connection to PLC. <BR>- Electrical sensors set at the following temperatures: 50°-60°-70°C. <BR>

Technical data

In laboratory tests carried out with mineral oil for hydraulic systems type CB68 (according to ISO 3498) with gradually increasing pressure, at 23°C, the weld stood up as follows: <BR>- HCY.76 14 bar<BR>- HCY.127 9 bar <BR>- HCY.254 8 bar <BR>In any case we suggest to verify the suitability of the product under the actual working conditions. If you need to use the indicator with other oils or fluids and under different pressure and temperature conditions, please contact ELESA Technical Department or carry out tests in order to guarantee a proper use.
