ProSense® float level switches provide a low-cost general purpose solution for monitoring of liquid level in a variety of applications. The float switches are available in several different material constructions for compatibility with many types of liquids, and offer wide temperature and system pressure ranges. Vertical and horizontal mounting styles are available for ease of installation. For long and trouble-free service, powerful internal permanent magnets actuate a highly reliable hermetically sealed reed switch. The switches have both AC and DC voltage ratings and are configured for normally closed operation; most models can be easily converted to normally open operation in the field. ProSense float level switches start at $9.50 and have a one-year warranty. Float level switch kits starting at $159.00 and float level tilt switches ($29.00 ) are also available.
