HCK. (inch sizes) Level indicators

Features and performances

Maximum fluid level visibility even from side positions.

Technical data

In laboratory tests carried out for a relatively limited time with the following liquids at a temperature of 73.4°F (23°C): mineral oil type CB68 (according to ISO 3498) or water/glycol-based solutions ( 50%), the resistance values were much higher than 0.507 psi (35 bar).

Maximum continuous working temperature:

266°F (130°C) (with oil, water, glycol-based solutions).

In laboratory tests these indicators showed an excellent resistance to temperatures up to 302/320°F (150/160°C) for many hours with pressures of 72.5/87 psi (5/6 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.

Special executions on request

• Built-in thermometer with red indication line (from HCK.127).

• External scale thermometer (Fig. 1) with probe in direct contact with the fluid.

• Special screw with nickel-plated brass tap (Fig. 3) to be fitted to the lower assembly end for any maintenance operation requiring the indicator exclusion.

 

Accessories on request (to be ordered separately)

SLCK kit for the electric control of a fluid level (Fig.2, from HCK.127) can be fitted, as needed, along the axis of the indicator with right (DX) or left (SX) connectors, normally closed (NC) or normally open (NO) contacts.
