In its standard design the temperature sensor is set such that a contact closes or opens when a temperature of 80 °C is reached (REED switch). The polyamide body consists of two parts, welded to each other with ultrasound for absolute tightness. Oil level indicators GN 650.6 can also be used in containers or vessels under pressure. Test series results of pressure load resistance are availa- ble. see also... • List of Oil Level Indicator Types → Page 1562 • Oil Level Indicators GN 650.8 (with Temperature Sensor) → Page 1574 • Oil Level Indicators GN 650.5 (with Electrical Oil Level Monitoring) → Page 1572 Information 2 Type NO Normally open NC Normally closed • 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 • 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 • Oil level indicators GN 650.6 with other temperature settings On request Original design HCX+ST
