The liquid level can be seen from the side despite the protective housing. The housing of the oil level indicator consists of two parts, which are welded together with ultrasound for a perfect seal. The oil level indicators are individually tested for leaks with an air pressure of 3 bar. Oil level indicators GN 650.2 can also be used in pressurized containers. Test series results for pressure resistance are available. The reflector is a colorless anodized aluminum strip with marking lines or a temperature scale. The scale is outside the liquid column and is therefore well protected. The oil level indicator is supplied with a ready-mounted protective housing. see also... • List of Oil Level Indicator Types → Page 1562 • Assembly Instruction → Page 1565 • Oil Level Indicators GN 650 → Page 1564 Information • Protective housing - - Zinc die casting P - - Plastic (Polyamide PA-HP) PT • Body plastic Crystal-clear Polyamide (PA 6-T) - - Ageing resistant - - High mechanical strength - - Temperature restistant 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 resp. scale • O-rings rubber - - Version P: NBR (Perbunan ® ) - - Version PT: FPM (Viton ® ) • Set screw, hexagon nuts, serrated lock washer - - Version P: Steel, zinc-plated, blue passivated - - Version PT: Stainless steel AISI 303 / AISI 304 • Plastic Characteristics → Page 2158 • Stainless Steel Characteristics → Page 2166 • RoHS Specification 3 1 l 1 b d l 2 l 3 l 4 l 5 l 6 l 7 l 8 l 9 s ≈ Max. wall thickness Thermometer scale °C °F 76 * 35,5 M 10 - 40 115 18 19,5 - 20 19 12 20 ... 100 68 ... 210 127 39 M 12 22 80 169 23 21 25 22 21 12 0 ... 100 32 ... 210 254 * 44,5 M 12 - 203 301 26 23,5 - 21 21,5 12 0 ... 100 32 ... 210 * only available in version PT Original design HCX-P/-PT-SST GN 650.2 Oil Level Indicators with Protective Housing
