SUBMERSIBLE LEVEL TRANSMITTERS

NOSHOK Series 612 Submersible Level Transmitters were designed to
provide a previously unequalled level of performance. Utilizing diffused
semiconductor and thin film technologies, Series 612 transducers are
accurate, shock resistant and extremely stable over long periods of time.
Reverse polarity protection and short circuit protection have been installed as
standard features. Lighting protection is optional.

Advanced manufacturing techniques combined with technologically
advanced standard features allow NOSHOK to offer a level of performance
previously found on transducers costing hundreds of dollars more.

A final electrical output and calibration inspection is performed on all
NOSHOK transducers prior to shipment to ensure 100% “out of the box”
reliability.
