C-Level™ Starter Box Combines Floatless Technology With Motor Control


SJE-Rhombus, an industry leader in providing pump control solutions for water and wastewater applications, introduces C-Level™ Starter Box Control Panels as a reliable means of controlling a 120 VAC single phase motor.  Common applications include pump chambers, sump pump basins, lift stations, dewatering and rain water harvesting. 

The C-Level™ sensor is an innovative, floatless solution, sensing the water level by converting water pressure to a frequency signal that is read by the C-Level™ Starter Box control panel.  Without any movement, the C-Level™ sensor is an excellent option for confined spaces. The C-Level™ Starter Box Control Panel utilizes a C-Level™ sensor to activate a power relay to turn the motor on and off. The C-Level™ Starter Box converts the C-Level™ signal to high and low level set points.  The C-Level™ Starter Box utilizes a NEMA 4X rated enclosure and includes start, stop and motor run indicator lights, manual run switch, and terminal block.  C-Level™ Starter Box comes standard with a C-Level™ sensor (4’ vent tube and 20’ wire). The entire system is UL/cUL Listed and is backed by a three-year limited warranty.


SJE-Rhombus is a leading control solutions provider, combining 35 years of expertise in pump controls with the latest technology to deliver energy efficient, cost-effective products for a wide variety of residential, commercial, municipal, industrial and agricultural applications.
