ProSense® SLT series submersible level sensors provide continuous liquid level measurement by sensing hydrostatic pressure produced by the height of liquid above the sensor and transmitting a 4-20 mA output signal. The SLT1 series has a slim 1-inch diameter housing and a ported bullet nose cap for protection of the sensor diaphragm. The series is available in cable lengths ranging from 30 feet to 140 feet and with sensing ranges of 0-5 psig to 0-50 psig. The SLT2 series features a large 2.75 inch diameter PTFE flexible diaphragm surrounded by a 316 stainless steel non-fouling protective cage and is available in cable lengths ranging from 30 feet to 100 feet and with sensing ranges of 0-5 psig to 0-30 psig. SLT series sensors start at $299.00 and have a one-year warranty, are CE marked and approved for intrinsically safe applications.
