New Hammer Union Pressure Transmitter
American Sensor Technologies releases its hammer union pressure transmitter for pressures up to 20,000 PSI.
Designed to operate in hazardous areas, the AST4400 and AST4600 hammer unions are available for non-hazardous, intrinsically safe, and explosion proof areas as well as SIL2 designs.
The product was developed through the process of listening to customers and applying the latest sensor technology and material to the applications. These intense applications cause sensors to drift and eventually fail in the field. The sensor is hammered during install and hammered with pressure transient. With this in mind, the AST hammer union pressure transmitter employs a thick Inconel™ 718 diaphragm and silicon strain gages to increase survivability and long term performance.
The transmitter is lab tested for high shock and vibration resistance, with testing up to 1000G. Further, AST field tested it onshore and offshore in the most extreme ambient conditions.
The modular design allows for simpler, faster, and lower cost replacement of the transmitter if a failure were to occur. The cage around the pressure transmitter is designed to protect the sensor and mating connector, allows for proper drainage in flooding situations, and optional handle mounting (although the cage itself is easy to hold with a gloved hand).
Short term, you have a transmitter that will last longer with less drift. Long term, you have a more cost-effective solution because you'll repair less and pay less when you repair.
