There is also the option to electrically detect the media temperature by means of a temperature sensor integrated in the lower casing section. To do so, a platinum resistor (PT 100) is used, the ohmic value of which increases virtually proportional with the temperature in the range from 0° and 100 °C. The polyamide housing consists of two parts, welded with ultrasound. Oil level indicators GN 650.8 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 650.3 (with Electrical Oil Level Monitoring) → Page 1568 • Oil Level Indicators GN 650.6 (with Electrical Oil Level Monitoring) → Page 1570 Information • Housing 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 2 marking lines • Temperature sensor Platinum resistor PT 100 (PTC) • O-ring, rubber NBR (Perbunan ® ) • Set screw, hexagon nut, serrated lock washer, sensor housing Steel, zinc plated, blue passivated • IP Protection Classes → Page 2153 • Elastomer Characteristics → Page 2158 • Plastic Characteristics → Page 2158 • RoHS Specification • Oil level indicators GN 650.7 with tempera- ture sensor and oil level monitoring On request 1 l 1 How to order 1 GN650.8-254 Original design HCX-E-ST
