AutomationDirect: Submersible level transmitters

Designed to provide liquid level measurement by continually sensing hydrostatic pressure produced by the height of liquid above the sensor, AutomationDirect’s ProSense SLT series submersible level transmitters is available in two styles: the SLT1 with 1-in diameter housing and a ported bullet nose cap for protection of the sensor diaphragm; and the SLT2 with 2.75 in diameter PTFE flexible diaphragm surrounded by a 316 stainless steel non-fouling protective cage.

The ProSense SLT series submersible level sensors also provide a 4-20 mA output signal compatible with PLCs, panel meters, data loggers, and other electronic equipment.

The SLT1 series is available in cable lengths ranging from 30 ft to 140 ft and with sensing ranges of 0-5 psig to 0-50 psig.

The SLT2 series provides reliability and long life in harsh environments, and is available in cable lengths ranging from 30 ft to 100 ft, with sensing ranges of 0-5 psig to 0-30 psig.

Both styles are fitted with a shielded cable containing an atmospheric vent tube and a tough polyurethane jacket, which incorporates an exclusive “water block” liner beneath the jacket. The cable is attached to the sensor using an over-molding process to prevent moisture intrusion.

Available accessories include: a desiccant vent filter to prevent moisture from entering the vent tube and damaging transmitters with vented gage reference pressure; aneroid bellows which fluctuate with changes in atmospheric pressure to maintain a constant barometric reference; junction boxes to provide a water-resistant enclosure for electrically connecting the transmitter cable to the user’s system via a terminal strip; and replacement nose caps to protect the sensing diaphragm.

Suitable for applications such as lift station monitoring, construction by-pass pumping, tank liquid level, wastewater, and slurry tank liquid level control, the ProSense SLT series submersible level transmitters are made in the USA. All sensors are backed with a one-year warranty, include UL and FM hazardous location approvals for intrinsically safe applications and are CE marked.
