A NEMA 4X clear front enclosure (7.9 X 4.7 X 3.5 inches) with two liquid-tight cable fittings (one in, one out), a terminal strip, and provisions for mounting either a drying tube or bellows assembly, each sold separately.

An alternative to the drying tube, this aneroid bellows requires no periodic maintenance.

Single eye mesh cord grip style cable hanger for use with KELLER Pressure’s 0.230 inch O.D. cables, including PE, Hytrel, and Tefzel.

Drying tube assembly - for vented cable when required

These custom built assemblies are designed to facilitate calibration and maintenance testing. Versions are available to connect the Acculevel, Levelgage, LevelRat, and Microlevel to a pressure calibrator.

The protective spacer anchors the LevelRat in place while positioning the sensing diaphragm off the bottom to avoid false readings caused by sludge and debris.

Aids in corrosion resistance as well as helps ensure that the cable remains taut in turbulent conditions.

Recommended for lightning/surge protection of user’s power supply/readout/PLC, etc. To be used in conjunction with Levelgage, Acculevel, LevelRat, Microlevel, Valueline, or Preciseline transmitters.
