Why does this sensor feature integrated hand-grips on the body?

Omni Instruments Expert Response: The integrated large hand-grips are an operator-centric safety feature designed for high-pressure oilfield environments. They allow field technicians to maintain a secure hold and achieve proper alignment during installation or removal, even when wearing heavy, oil-slicked safety gloves or working in Arctic conditions.

How does the 1ms response time benefit fracking and mud-logging operations?

Omni Instruments Expert Response: In high-intensity operations like hydraulic fracturing, pressure transients can occur almost instantaneously. A 1ms response time ensures that the data logging system captures these rapid spikes in real-time, allowing for immediate safety shutdowns or pump adjustments that slower industrial sensors (often 50ms+) would miss.

Can the Hammer Union sensor be used with corrosive or abrasive drilling fluids?

Omni Instruments Expert Response: Yes. The wetted parts are constructed from high-grade 316 Stainless Steel, providing excellent resistance to aggressive chemical media and abrasive drilling muds. Furthermore, the wide-port pressure contact face is designed to be "self-draining," preventing the buildup of viscous cement or mud that could otherwise clog the sensor.

What electrical termination options are available for hazardous zones?

Omni Instruments Expert Response: For ATEX/IECEx certified deployments, we offer several heavy-duty options, most commonly the Bendix PTIH-10-6P (aviation-style) 6-pin connector. We can also provide integral waterproof cables with high-integrity glands for permanent installations where a plug-and-socket connection isn't preferred.

Is this sensor compatible with all Figure 1502 Hammer Unions?

Omni Instruments Expert Response: The OHU series is designed as a standard 1502-compatible "Sub," making it interchangeable with most major oilfield manifold hardware. However, because these are made-to-order, we can adjust the dimensions and pressure ratings (up to 1400 Bar) to ensure compatibility with specialized or legacy high-pressure systems.

What does NACE MR0175/ISO 15156 compliance mean for hammer unions?

Omni Instruments Expert Response: It certifies that the metallic materials used in the union are resistant to sulphide stress cracking and stress corrosion cracking in "sour" environments containing hydrogen sulphide (H2S).

Can I use my own sensor with an Omni Hammer Union?

Omni Instruments Expert Response: Yes. We can provide the NACE-compliant hammer union sub with a specific internal thread and access port, allowing you to integrate your own specialised pressure or temperature instrumentation into a standard 1502 connection.

Why is NACE compliance critical in oilfield pressure monitoring?

Omni Instruments Expert Response: High-pressure sour gas service can cause standard steels to become brittle and fail catastrophically; NACE-compliant materials (like Inconel 718 or specific heat-treated steels) ensure structural integrity and safety in these corrosive conditions.

Description

Description

The Omni Hammer Union Pressure Sensor is a modular, field-hardened solution engineered for the most demanding high-pressure environments in the oil and gas industry. Built around a standard Figure 1502 union, the sensor features a signature slimline 316 Stainless Steel body with integrated heavy-duty hand grips, allowing for safe and rapid installation by operators in extreme weather conditions. With an ultra-fast 1ms response time and high-vibration resistance, this sensor is the industry benchmark for real-time monitoring in fracking, mud logging, and cementing operations. Fully customizable to meet specific project needs, it can be configured with pressure ranges up to 1400 Bar, multiple signal outputs (4-20mA or 0-10V), and ATEX/IECEx hazardous area certifications, providing the reliability required for critical wellhead and manifold safety.

The Omni Hammer Union is made from Stainless Steel for high strength and anti-corrosion properties. The body has been specially designed with the operator in mind;

Large hand grips for a secure hold in the toughest conditions.
Open the tool port for easy access to the pressure transmitter.
Wide pressure contact face for an instant response to pressure changes, quick drainage, and fewer opportunities for obstructions or blockages.

The unique design offers advanced protection to the pressure transmitter and electrical connection while still offering a stable accurate method of pressure measurement. The body is slimline for easy access and installment to hammer union fittings. Featuring large openings for easy grip even with gloves on. Stainless steel 316 construction provides maximum protection against adverse weather conditions, corrosion resistance against chemicals, and robust protection when in use. A large pressure port offers instant pressure response time while allowing a quick drainage feature.

All pressure transmitters can be specified for individual applications, allowing for the correct pressure range to be accurately measured. Pressure transmitters come in a range of sizes with a typical accuracy of 0.2% FS or better. Built-in temperature compensation and a usable operating range of -40 to 125°C. Ultra-fast response time of 1ms across 10-90% of the pressure range. Designed to operate in hazardous areas with Atex, IECEx approval.

While the OHU-1000 sensor itself is currently listed as 316 Stainless Steel, we can provide the 1502 Hammer Union fitting with NACE-compliant materials and custom threading to host your third-party sensors.
