For this purpose there is a magnetic float in the indicator which at a spe- cified liquid level (liquid min. level) will close or open a contact in a REED switch. The polyamide body consists of two parts, welded with ultrasound. Oil level indicators GN 650.3 can also be used in pressurised containers. Pressure test results regarding resistance under pressure are available. see also... • List of Oil Level Indicator Types → Page 1562 • Oil Level Indicators GN 650.5 (with Electrical Oil Level and Temperature Monitoring) → Page 1572 • Oil Level Indicators GN 654 (with and without Electrical Oil Lever Monitoring) → Page 1576 Information • Body plastic Crystal-clear Polyamide (PA-T) - - Ageing resistant - - High mechanical strength - - Temperature resistant up to 90 °C - - Solvent resistant, but not suitable for alcohol - - Avoid contact with hot water • Reflector aluminum - - White lacquered - - With two black marking lines • Float plastic Black • O-rings Rubber NBR (Perbunan ® ) • Set screw, hexagon nut, serrated lock washer Steel zinc plated, blue passivated • IP Protection Classes → Page 2153 • Elastomer Characteristics → Page 2158 • Plastic Characteristics → Page 2158 • RoHS Specification Original design HCX-E
