SJE-Rhombus is a leading provider of innovative and reliable control solutions for water and wastewater applications. Founded in 1975 and headquartered in Detroit Lakes, Minnesota, USA, the company has established a reputation for excellence in the industry, offering a range of products and services that meet the diverse needs of its customers. One of SJE-Rhombus's key product offerings is its line of level switches. These switches are designed to detect liquid levels in a wide variety of applications, from residential sump pumps to large-scale industrial tanks. SJE-Rhombus offers a range of level switches to meet different needs, including float switches, ultrasonic level sensors, and capacitance level sensors. Float switches are simple, cost-effective devices that are ideal for use in residential and commercial applications. They consist of a buoyant float that is attached to a switch, which activates when the float reaches a certain level. SJE-Rhombus offers a range of float switches, including those with single and dual floats, high-level alarms, and built-in pump controls. Ultrasonic level sensors are more sophisticated devices that use sound waves to detect liquid levels. They are ideal for use in applications where precise measurements are required, such as in tanks with irregular shapes or where there are obstructions in the tank. SJE-Rhombus offers a range of ultrasonic level sensors, including those with analog and digital outputs, as well as those that can be programmed for specific applications. Capacitance level sensors use an electrical field to detect liquid levels, making them ideal for use in applications where non-conductive liquids are being measured. They are also well-suited for use in applications where the liquid level is changing rapidly, such as in mixing tanks or where there is agitation. SJE-Rhombus offers a range of capacitance level sensors, including those with multiple probes and those with adjustable sensitivity. In addition to its level switches, SJE-Rhombus also offers a range of services to support its customers. These services include custom design and engineering, technical support, and training programs. SJE-Rhombus is committed to providing the highest level of customer service, and its team of experienced professionals is always available to help customers with any questions or concerns they may have. Overall, SJE-Rhombus is a trusted provider of reliable and innovative control solutions for water and wastewater applications, and its line of level switches is just one example of the company's commitment to meeting the diverse needs of its customers. With a focus on quality, reliability, and customer service, SJE-Rhombus is well-positioned to continue its growth and success in the industry for years to come.
