Liquid level sensors

These polysulfone level switch units are both compact and economical. They feature a variety of mountings, power requirements and electrical terminations to make it easy to find a perfect match for your application. The ELS Level Switch Series is low cost, compact, optical, level sensors with built-in switching electronics. With no moving parts, these small units are ideal for a variety of point level sensing applications especially where dependability and economy are a must. These level switch units are suitable for high, low or intermediate level detection in practically any tank top, large or small. Installation is simple and quick through the tank top, bottom or side. Solid state-switching ensures dependability over long service life. The sensor offers ±1 mm repeatability and broad liquid compatibility. They are not recommended for use in any liquid that crystallises or leaves a solid residue.

The XLS-1 - Ultrasonic Level Sensor is Gems' rugged alternative to reed switch level sensors. They are compatible with water, water-based and hydrocarbon-based liquids, and are perfect for applications where foam and condensation may affect other sensing technologies. The XLS-1 is an ideal solution for sensing liquid level in generators, water tanks, radiators, printers, and other harsh industrial applications. These Ultrasonic Level Sensors are designed for reliable performance during the most challenging applications. The XLS-1's compact design allows for maximum flexibility and comes with six mounting options to ensure the sensors fit each customers specific application. There are no moving parts on the XLS-1, which means normal part wear won't be an issue.

The durable construction of these switch designs ensures long, trouble-free service. Because the effects of shock, wear and vibration are minimised, these hermetically sealed switches provide precise repeatability with no more than 1% deviation. The switch actuation points remain constant over the life of the unit. Ideal for shallow tanks or restricted spaces, or for any low-cost, high volume use.

The FS-480 large-body inline flow switch delivers ample flow rates with minimal pressure drop. 25% larger than its FS-380 sibling, the FS-480 is ideal for processes that push more fluid through their systems and demand low pressure drops. Designed to accommodate the Semiconductor Industry's move to larger 300 mm wafer and cross-over equipment, this switch is also perfect for critical medical equipment applications. A glass-reinforced PPS piston and forged 316 stainless steel body make this sensor rugged enough for high pressure lubrication and cooling systems as well. This simple, yet meticulously perfected design provides the reliability required in critical applications while allowing for much lower pressure drop rates than other available switches.
