The ProSense SLT series submersible level sensors provide continuous liquid level measurement by sensing the hydrostatic pressure produced by the height of liquid above the sensor and providing a 4-20 mA output signal compatible with PLCs, panel meters, data loggers, and other electronic equipment.
- The SLT1 series has a slim 1-inch diameter housing and a ported bullet nose cap for protection of the sensor diaphragm.
- The SLT2 series features a large 2.75 inch diameter PTFE flexible diaphragm surrounded by a 316 stainless steel non-fouling protective cage.
- A shielded cable with atmospheric vent tube and a tough polyurethane jacket is attached to the sensors using an over-molding process that prevents moisture intrusion.
- Accessories include a desiccant vent filter, aneroid bellows, junction boxes, and replacement nose caps.

Vent Filter (Desiccant) for Submersible Level Transmitters
Vent filters utilize indicating desiccant to prevent moisture from entering the vent tube and damaging transmitters with vented gage reference pressure.
- The desiccant will turn from blue to pink when exposed to moisture indicating the need for maintenance
- The vent filter design prevents moisture from entering the vent tube for at least one year without maintenance
The SLFT-VF1 vent filter is
$25.00
(SLT-VF1)
Aneroid Bellows for Submersible Level Transmitters
The aneroid bellows is a maintenance-free alternative to desiccant filters for moisture protection on vented gage transmitters.
- Made of flexible neoprene material attached to a polycarbonate mounting bracket
- The bellows fluctuates with changes in atmospheric pressure, maintaining a constant barometric reference
- The use of the bellows results in a closed reference pressure system subject to zero shift errors induced by changing temperatures of up to 0.003 psi/°C.
The SLT-AB1 aneroid bellows is
$39.00
(SLT-AB1)
Junction Boxes for Submersible Level Transmitters
The submersible level transmitter junction boxes provide a water-resistant enclosure for electrically connecting the transmitter cable to the user's system via a terminal strip.
- The enclosure also provides a convenient location for terminating the transmitter's vent tube to a vent filter or an aneroid bellows
- Junction box enclosure is constructed of polycarbonate with a clear top incorporating a neoprene seal
- The junction box is rated IP56
Junction boxes for submersible level transmitters are
$162.00
(SLT-JB1)
Replacement Nose Caps for Submersible Level Transmitters
Submersible level transmitter replacement open-face and ported bullet nose caps.
-
The open-face nose cap offers the best
resistance to clogging.
This single-piece nose cap provides maximum exposure of the sensing diaphragm to the liquid media through a protective perforated screen on the front. The open-face nose cap is constructed from molded polyoxymethylene (POM). -
The ported bullet nose cap offers the
best protection against damage to the sensing diaphragm.
This single-piece nose cap allows the liquid media to enter through six 1/8" holes around the outside and includes a #8-32 UNC-2B threaded hole on the front. The closed-face nose cap is constructed of molded polyoxymethylene (POM).
Replacement nose caps are
