Keller Analog Acculevel
Brand: Keller America
The Keller America submersbile pressure transducer provides standard features that far exceed those of comparably priced transmitters, including standard ±0.25% FS or optional ±0.1% Total Error Band (TEB)3 accuracy.
The ability of the Acculevel to provide this level of sustained performance over a wide range of operating conditions makes it ideally suited to environmental monitoring applications such as surface water, streams, and reservoirs.
Keller America’s guaranteed lightning protection makes this transmitter ideal for installation in areas prone to chronic damage due to transients caused by lightning.

Optional Accessories for Keller Pressure Transducers
Drying Tube Assembly - 900001.0002
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)
Bellows Assembly - 900001.0009
Bellows
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
Cable Hanger - HU02216001
Single eye mesh cord grip style cable hanger for use with KELLER’s 0.230 inch O.D. cables, including PE, Hytrel, and Tefzel, used on Acculevel, Digilevel, Levelgage, LevelRat, Microlevel, and Nanolevel submersible level transmitters, and KELLER’s Valueline and Preciseline pressure transmitters.
Stabilizing Weight - 900001.0033
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.
Sour Gas Trap
Effectively prevents any H2 S vapor from migrating down the 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 America Drying Tube.
