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.

Screw, nuts and washers

Zinc-plated steel.

Packing rings

NBR synthetic rubber O-Ring.
Suggested roughness of the packing ring application surface Ra = 3 µm.

Float

Polyamide based (PA) expanded technopolymer, black colour, with a built-in magnetic element to activate the electric contact when the oil level drops to a minimum; alarm threshold located at about 50 mm from the centre of the lower nut (in presence of mineral oil type CB68, according to ISO 3498, at 23°C).

Sensor bracket

Watertight in polypropylene based (PP) technopolymer, black colour, with a built-in relay (reed) with two conductors wired to the two-pin connector.
For a correct assembly see Warnings.

MAX temperature electrical sensor (80°C)

Zinc-plated screw with built-in sensor.
Temperature of intervention is 80°C.

Swivelling two-pin connectors

With built-in cable glands and contact holders. Front or side output (right or left) including protection against water sprays (protection class IP 65 according to EN 60529 table) that can be increased during installation with the necessary adjustments. Flat NBR synthetic rubber packing rings.

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

  • HCX-E-ST-NO: with electrical contact normally open.
  • HCX-E-ST-NC: with electrical contact normally closed.

Mounting

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

90°C (with oil).

General information

Features and performances

This column level indicator generates two electric signals: one when the oil goes down to the minimum level allowed and the other one when the temperature reaches the pre-set degrees (80°C).

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 13 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.

Electrical features

Functioning of the electrical sensors

  • HCX-E-ST-NO with electrical contacts normally open.
MIN level electrical sensor: the electrical circuit is closed when the minimum level is reached.
MAX temperature electrical sensor: the electrical circuit is closed when the pre-set temperature at 80°C is reached.
  • HCX-E-ST-NC with electrical contacts normally closed.
MIN level electrical sensor: the electrical circuit is open when the minimum level is reached.
MAX temperature electrical sensor: the electrical circuit is open when the pre-set temperature at 80°C is reached.

Instructions of use

Two-pin connectors assembly instructions

  1. Remove the connectors from the indicator by unscrewing the set screw placed in the bottom, take the contact holders out and loosen the cable glands.
  2. Slip on the two-pole cable into the connectors (standard connectors) and connect the wires to the terminals nr. 1 and nr. 2 of the relative contact holders.
  3. Assemble by pressing the contact holders into the realtive connectors in the required position.
  4. Screw the connectors to the indicator and then tighten the cable glands.
