IP65 float level indicators can be cut to length
Elesa's new HFLT/E float level indicators are the latest addition to the company's range of column level indicators. They are intended for greater ranges of level reading than conventional side-mounted visual systems - especially where the tank concerned is remote or otherwise inaccessible so that electronic indication is needed. This is particularly appropriate on construction equipment, building facilities tanks, large vehicles, factory machinery sumps and similar plant and equipment.
The Elesa HFLT/E units are easily customisable by simply cutting the float rod to suit the tank and max/min fluid level required. HFL/E and HFLT/E level indicators can be used to detect the minimum or maximum level of liquid in a tank. HFL/E indicators are available with normally-open contacts for minimum level detection, or with normally-closed contacts for maximum level detection.
Both models consist of a polyamide-based technopolymer body with a connector and sensor block, protected to IP65. Dipsticks are AISI 304 stainless steel tube for the HFL/E model and polyamide-based technopolymer for the HFLT/E model, with a float in NBR synthetic rubber for the HFL/E and polyamide-based technopolymer for the HFLT/E. The maximum continuous working temperature is 80degC. Two standard fittings are available for assembly: with threaded coupler, or a flange with holes for screw fastening.
Sensor magnet HFLT/E indicators allow reversal of the polarity so that it is possible to use the same indicator for both minimum and maximum level detection. Easy access is provided to the magnet by simply loosening the fastening nut. The float unit has no parts and is integral to the dipstick, making these indicators suitable for use in tanks containing dirty liquids, water, oil or coolant oil, and with ferrous metal parts or foams. Moreover, the operation is independent of the fluid's electrical conductivity. Further information may be found at www.elesanow.co.uk.
