Sensor holder bracket

In black polyamide based (PA) technopolymer, watertight, incorporating the relay (reed) with two conductors wired to the connector.

It can be moved along the axis of the indicator and secured in the preferred position with the appropriate screw (set screw) in technopolymer.

Electric sensor

With NO and NC (initial status of the reed sensors) we mean the condition of the electrical contact when the tank is full and therefore the float is in the upper position (Fig.1).

• NC: the electrical circuit closes when the float crosses the sensor during the tank filling phase. In the same way, the electrical circuit opens when the float passes through it during the emptying phase of the tank.­

• NO: the electrical circuit opens when the float crosses the sensor during the tank filling phase. In the same way, the electrical circuit closes when the float passes through it during the emptying phase of the tank.

Float

Polypropylene based (PP) technopolymer, max temperature limit 80° C or polyamide based (PA) technopolymer, max temperature limit 120°C, max chemical compatibility, black colour.

The float incorporates a magnetic element to activate the electric contact. When the float reaches the intervention level set by the user, by suitably positioning the sensor holder along the axis of the indicator, the electrical contact activates.

Max operating pressure 2 bar (operation with oil)

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.

Male connector

• 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) can be increased during installation with the appropriate precautions.

NBR synthetic rubber packing ring.

Kit

The kit includes one or two sensor holder brackets, a float, 4 O-rings (2 FKM for HCK-GL and 2 NBR for HCK), two spacers and two M12 UNI 5589 AISI 316 stainless steel nuts.

It is possible to apply more than one kit to get the electric control of different levels, consistently with the height of the transparent column.
