APG HU1502I Recalibratable Incoloy Hammer Union Pressure Transmitter

APG HU1502I Recalibratable Incoloy Hammer Union Pressure Transmitter is designed for the rugged environments of land-based and offshore drilling installations, including Mud Logging and Measurement While Drilling.

The incoloy wetted material is NACE compliant and suitable for sour gases. And the recalibration port allows for digital zero and span setting. With all that, and Class I, Div 1 Intrinsically Safe certification, the HU1502I delivers accurate measurements in the most adverse conditions. Intrinsically safe, sour gas compatible, and recalibratable. The toughness you need in a Hammer Union Pressure Transducer, now with a recalibration port.

APG HU1502I Recalibratable Features

  • Ranges to 20,000 psi
  • 4-20 mA or 0-5 VDC output
  • WECO® 1502 fitting for 2” line
  • ±0.25% accuracy of full scale
  • Exceptional shock and vibration resistance
  • Digital recalibration port
  • CSA/ATEX/IECEx Approval

Certified & Ready

The HU1502I is certified for global use in hazardous locations through CSA (Class 1, Div 1/Zone 0), ATEX (CE 0344 EX II1G Ex ia IIB T4 Ga), and IECEx (EX ia IIB T4 Ga). It’s also NACE MR-01-75 and ISO 15156-3 compliant for sour gasses.


You can recalibrate the transmitter via the recalibration port, with a PC and APG’s recalibration software.

Smart(er) Design

Thanks to your feedback, we continue to improve on our customer-centric design. We’ve removed screws to withstand vibration better, without compromising the toughness and performance you depend on.
