Hammer Union Transmitters are used in a wide variety of harsh and viscous oil & gas exploration and drilling applications both onshore and offshore. A Hammer Union is a pipe connection designed to be loosened or tightened by hammer blows on protrusions known as hammer wings. A Hammer Union is usually used on high pressure lines where quick disconnections are necessary.

Due to the demands placed on these sensors, shock and vibration resistance are key in their design. Hammer Union Transmitters are ruggedly constructed for use with highly abrasive and corrosive media, and are specifically designed to withstand harsh environments such as acidizing, blowout preventers, choke & kill manifold, fracturing & cementing, new well development and extraction, oil and gas drilling, service and cement trucks, standpipe, stimulation, mud logging and mud pumps, oil field & offshore, and well head pressure measurement.

Hammer Union Transmitters monitor circulating systems to measure mud and media flow during the extraction processes. They can reduce downtime and lower service costs by providing accurate, reliable data to detect slight changes in pressure, so that media flow pressure can be quickly adjusted during drilling operations. Drilling operators can then maximize oil withdrawal rates and monitor potentially hazardous conditions such as gas bubbles to increase safety and efficiency. They are easily replaced on location, which provides convenience and fast response time.

Constructed with a heavy-duty Inconel X-750 diaphragm and connection, NOSHOK’s Intrinsically Safe Hammer Union Transmitter features a 2” 1502 wing union, offers ranges from 5,000 psig through 20,000 psig and has a 4 mA to 20 mA, 2-wire output signal.

Each NOSHOK sensor comes with a Certificate of Calibration. This NOSHOK transmitter is CSA compliant for hazardous location equipment and also NACE MR0175/ISO 15156 compliant.
