Assembly ends

Glass-fibre reinforced polyamide based (PA) technopolymer, black colour.

Support

Aluminium in natural colour.

Graduated contrast screen

White lacquered aluminium. It can be taken out before assembly to allow the insertion of level lines or words.

Float

Technopolymer, black colour, with a built-in magnetic element to activate the electric contact when the float reaches the contact threshold located at about 55 mm above the axis of the lower screw (data referred to mineral oil type CB68, according to ISO 3498, temperature 23°C).

Spacer sleeves

In polyamide based (PA) technopolymer. Essential in cases where the reservoir is made out of ferromagnetic material in order to prevent the interaction between the magnet and the metal mass of the reservoir.

Bracket with male connector

Perfectly watertight, incorporating the relay (reed) with two output conductors (NO and NC version) and/or with MAX temperature sensor (80°C) and/or temperature probe.

  • DIN 43650 C connector in glass-fibre reinforced polyamide based (PA) technopolymer, black colour.
  • 4-pole M12x1 connector, with threading in glass-fibre reinforced polyamide based (PA) technopolymer certified self-extinguishing UL-94-V0, black colour, matte finish.

For a correct assembly see Warnings.

Female connector (DIN 43650 C)

With built-in cable gland and contact holder. Front or axial output (high or low) ensuring protection against water sprays (protection class IP 65 according to table EN 60529).

Standard executions

See configuration table.

 
 

Features and performances

The HCK-E-S level indicator with lateral connector output allows the level of intervention of the sensor to be minimised.

In case of use of an extension with angled connector, the direction of the cable output is shown in Fig.1.

Technical data

In laboratory tests carried out for a relatively limited time with the following liquids at a temperature of 23° C: mineral oil type CB68 (according to ISO 3498) for HCK, mineral oil type CB68 (according to ISO 3498) water or water/glycol-based solutions ( 50%) for HCK-GL, the resistance values were much higher than 35 bar.

For use with fluids other than mineral oils and under particular 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.

Functioning of the MIN level electrical sensor

  • NO: the electrical contact closes on reaching the minimum level.
  • NC: the electrical contact is opened when it reaches the minimum level.

Functioning of the temperature electrical probe (STL)

The working principle of the temperature probe is to measure the variation of resistance of a platinum element: 100 ohm = 0°C, 138.4 ohm = 100°C.

The function between temperature (T) and resistance (R) is approximately linear over a small temperature range: for example, if you assume that it is linear over the 0° to 100°C range, the error at 50°C is 0.4°C.

For precision measurement, it is necessary to linearise the resistance to give an accurate temperature. The most recent definition of the function between resistance and temperature is International Temperature Standard 90 (ITS-90). The function between resistance and temperature, obtained in laboratory tests, measuring directly the resistance value on the contacts is shown in the graph. We suggest, anyway, to set the system in order to compensate both heat dissipation and cable resistance.

The temperature variation of 1°C causes a 0.384 ohm variation in the probe resistance. Therefore, even a small error in the resistance measurement (for example, if the resistance of the cables connecting to the probe were not considered) translates into a significant error in the temperature measurement.

Because of the low signal levels, it is important to keep any cables away from electric cables, motors, switchgear and other devices that may emit magnetic or electrical noise. Using screened cable, with the screen grounded at one end, may help to reduce interference.

Furthermore, if long connection cables are used, make sure that the signal measurement and reception device is designed to compensate for the resistance of the cables themselves.

Female connector assembly instructions

  • Remove the connector from the indicator by unscrewing the set screw placed on the connector, take the contact holders out and loosen the cable gland.
  • a) HCK-E-ST: insert the cable into the connector (standard connector) and connect the wires to terminals 1 and 2 for the operation of the MIN level sensor, to terminals 3 and ground (4) for the operation of the MAX temperature sensor.
  • b) HCK-E-STL: insert the cable into the connector (standard connector) and connect the wires to terminals 1 and 2 for the operation of the MIN level sensor, to terminals 3 and ground (4) for the operation of the temperature probe.
  • 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.
