Oil Level Regulator

The Q Series level sensors use an optical infrared sensor. This robust and reliable measurement principle is equally suitable for all functions in oil systems, such as minimum level monitoring, refill monitoring, pump on/off control, flow monitoring, and more. Another advantage is the wide supply voltage range of 10–28 V DC. Beyond the lubricating oil range, the sensors are suitable for use with many other liquids, such as water, seawater, glycol-based coolant, diesel, kerosene, and gear oil. A compatibility list is available upon request. The sensors’ operation is independent of the liquid’s density, conductivity, turbidity, color, temperature, or contamination. The sensors stand out for their easy installation, compact design, reliability, resistance to vibration, and the fact that they contain no moving parts subject to wear—they are solid-state components. The level controller operates on the optoelectronic principle and contains an infrared LED and a light receiver. The light from the LED is directed toward a glass prism. As long as the prism is surrounded by oil, part of the light beam is deflected, allowing that portion of the light to reach the receiver. If the oil level drops below the glass prism, the full infrared beam is reflected to the receiver and triggers a switching operation.The following accessories can be added as needed:Frog’s Eye, up to 1 bar (alternative to the prism sight glass) Metal housing, up to 5 bar (alternative to the prism sight glass) Coarse filter with extension for open compensation line
