InnovaSwitch™ Level Switch
Overview The InnovaSwitch insertion-type level switch is a high-performance, industrial-grade liquid level indicator for tanks and process vessels. This product switches on level changes as small as 0.03 inch (0.8 mm) on dry-to-wet and wet-to-dry occurrences in a tank or vessel. The instrument was designed for heavy industrial environments, including high temperature and high pressure. Flow and level detection is accomplished by using a high-resolution thermal differential technique. The sensor consists of a pair of matched Resistance Temperature Detectors (RTD’s). One RTD is self-heated using a constant DC current. The other RTD is unheated and provides an accurate process temperature reference. The thermal differential created between the reference and the heated RTD pair is a function of the density and/or velocity of the media with which the sensor is in contact. Product Benefits Built for heavy industry Liquid level switch for the detection of the liquid level in tanks and process vessels Industry-leading performance switch alarm triggered on level change as small as 0.03 inch (0.8 mm) High-temperature version available Exotic materials upon request: Standard: 316L series stainless steel Exotics: Hastelloy, Monel, Inconel and others Two-year workmanship warranty Removable plug-in electronics Free of all moving parts that can stick, coat or fail Self-heating sensor design improves repeatability No separate heater to fail or slow response time
