Product Overview
SENEX DG1300-YR Hammer Union Pressure Transmitter
DG1300-YR
Engineered specifically for demanding oilfield applications, the SENEX DG1300-YR Hammer Union Pressure Transmitter delivers high-accuracy, heavy-duty pressure monitoring in extreme environments. Featuring a ruggedized all-welded housing, standard 1502 wing union connection, and superior resistance to heavy shock, intense vibration, and water hammer, this intelligent pressure sensor is optimized for mud pumps, cementing, fracturing, and wellhead monitoring. With optional HART protocol integration and field-proven reliability under extreme pressure up to 100 MPa, it ensures seamlessly continuous performance and long-term operating stability across severe oil and gas exploration sites worldwide.
The SENEX DG1300-YR Hammer Union Pressure Transmitter is a specialized, high-performance pressure measurement instrument custom-designed for rugged well-site operations, offshore oilfields, and heavy industrial processing. Built around international high-precision sensing components and advanced digital compensation circuitry, the transmitter effectively converts high-pressure media dynamics into standardized 4–20 mA current output signals with superposed HART digital communication. Designed with a heavy-gauge 1502 hammer union process interface, the transmitter easily integrates into high-pressure manifolds, mud logging systems, and high-vibration piping networks without risking fluid leakage or structural fatigue. Its field-proven robust construction protects internal electronics from intense mechanical impacts, sudden pressure spikes, and harsh environmental exposure, making it an indispensable asset for oil and gas engineers seeking absolute reliability during critical well servicing operations.
Beyond its exceptional mechanical durability, the DG1300-YR transmitter offers versatile system compatibility, wide temperature range performance, and user-friendly maintenance. The sensor features specialized high-grade stainless steel wetted materials compatible with viscous, abrasive, and corrosive media such as drilling mud, crude oil, fracturing fluid, and concrete slurry. Engineered with anti-lightning, anti-RFI/EMI interference protection, and zero/span adjustments, this unit maintains tight accuracy ratings of 0.25%, 0.5%, or 1.0% FS across extended service lives. Whether deployed in automated onshore drilling rigs or remote oilhead telemetry systems, the SENEX DG1300-YR provides high-precision data integrity, operational safety, and full traceability backed by state-of-the-art laser marking and rigorous international manufacturing standards.
FAQ
