KELLER offers a variety of optional accessories designed to enhance versatility, simplify the installation, and increase the longevity of your KELLER pressure or level transmitter.

Bellows Assembly

Alternative to the drying tube, this aneroid bellows attaches to cable vent tube and requires no periodic maintenance. Note that the use of the bellows results in a closed reference pressure system subject to zero shift errors induced by changing temperatures of up to 0.0004 psi/ºC. Not recommended for use with accuracy requirements of ±0.25% FS or better, or ranges < 2 psi.

Termination Enclosure

Convenient option complementing gauge-type pressure/level transmitters, where it is desired to terminate the transmitter cable close to the measurement point. It includes 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 both a drying tube or bellows assembly, each sold separately.

Drying Tube Assembly

Clear tube filled with indicating desiccant that attaches directly to cable vent tube to intercept water vapor. Highly recommended when operating in high humidity conditions. Must be periodically renewed as desiccant becomes saturated, turning color from blue (dry) to pink (saturated).

Piezometer Nose Cap

The piezometer nose cap allows the unit to be buried in saturated soil without damage to the sensor diaphragm. The piezometer nose cap is available for Levelgage, Acculevel, and Acculevel SDI submersible level transmitters.

Pressure test adapter

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.

Protective Spacer

The Protective Spacer is an option for KELLER's LevelRat wastewater level transmitter. It provides an easy way to hold the LevelRat in place while keeping the sensing diaphragm elevated slightly allowing reliable readings even in the presence of sludge.

Stabilizing Weight

Zinc prop shaft anode adapted to fit Ø21 mm O.D. of Levelgage, Acculevel, and LevelRat submersible level transmitters. Aids in corrosion resistance as well as helps ensure that the cable remains taut in turbulent conditions.

Cable Hanger

Single eye mesh cord grip style cable hanger for use with KELLER's 0.230 inch O.D. cables
