Termination Enclosure
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.
Bellows Assembly
no periodic maintenance.
Note: 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.Edition 02/2024 Subject to alterations

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).
Sour Gas Trap
atmospheric vent of the level transmitter, on account of its
ability to absorb and trap any such vapors which enter it.
The Sour Gas Trap is intended to be installed either stand-alone or in tandem with a KELLER Drying Tube.
