SELF-SANITISATION AGAINST BACTERIA AND FUNGI
Close
HCY-E Electrical level indicators
with MIN level electrical sensor, transparent technopolymer
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.
Screws
Nickel-plated brass with hexagon socket.
Packing rings
NBR synthetic rubber O-Ring.
Float
Polyamide based (PA) technopolymer in red colour, with a built-in magnetic element to activate the electric contact when the oil level drops to the minimum set at 40mm over the screw axis (dimension l).
Sensor bracket
Watertight, black colour, with a built-in relay (reed).
For a correct assembly see Warnings.
Connector
Right side output including protection against water sprays (protection class IP 65 according to EN 60529.
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 before assembly to allow the insertion of level lines or words.
Standard executions
- HCY-E-NO: electric contact normally open that closes when the minimum level is reached.
- HCY-E-NC: electric contact normally closed that opens when the minimum level is reached.
Maximum continuous working temperature
80°C (with oil).
General information
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: 14 bar (HCY.76), 9 bar (HCY.127) and 8 bar (HCY.254).
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.

Instructions of use
Two-pin connector assembly instructions
- Remove the connector from the indicator by unscrewing the set screw placed in the bottom, take the contact holder out and loosen the cable gland.
- Slip on the two-pole cable into the connector (standard connector) and connect the wires to the terminals nr. 1 and nr. 2 of the contact holder.
- Assemble by pressing the contact holder into the connector in the required position.
- Screw the connectors to the indicator and then tighten the cable glands.
