• Description
The HU (Hammer Union) pressure transmitter was designed for the rugged
environment of land-based and offshore drilling installations.
APG’s HU is an extremely rugged pressure transmitter. It is designed
specifically for use with the 1502 Hammer Wing Union. These units are
constructed from materials designed for service with highly abrasive and
corrosive media and comply with new NACE standards.
