Designed for the rugged environment of land-based and offshore drilling installations The HU Hammer Union 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 NACE MR-01-75 and ISO 15156-3 standards.
Applications
The HU is designed specifically for the harsh environment in the oil patch including mud logging, cementing, fracturing, and acidizing applications.
Intrinsically Safe Hammer Union Pressure Sensor
- Ranges from 0 to 15,000 psi
- 4-20 mA or 0-5 VDC output
- 1502 fitting (2202 fitting also avaliable)
- Temperature compensated
- Complies with NACE standards for sour gas pressure applications
- Shunt Cal for testing full output
- Short lead times--as little as 2 weeks
