The NOSHOK Series 627 level transmitter combines the reliability and long life of diffused semiconductor and sputtered
thin film strain gauge sensors with safe electronics for outstanding performance and value. These transmitters were
designed for applications that require liquid level measurement in hazardous environments. All wetted parts are made of
stainless steel welded with no internal O-rings, gaskets or seals.

NOSHOK Series 627 pressure transmitters are available with a stainless steel nosecone, a stainless steel weighted
nosecone or NPT adapter and ranges to suit most applications. All units undergo extensive testing during the
manufacturing process to ensure that the highest performance is achieved in the demanding environments found in today’s
applications. Series 627 transmitters are Factory Mutual approved.
