The sensor uses a high-quality strain gauge design with a robust stainless-steel case to ensure durability in harsh field conditions. A shielded instrument cable (up to 200 feet recommended) connects the sensor to the transmitter, minimizing electrical noise for reliable data transmission. The system is field repairable and designed with no moving parts or fluids, reducing maintenance needs and enhancing reliability.

The 2021 Pressure Transmitter System delivers accurate, dependable pressure measurement critical for monitoring and controlling high-pressure equipment in oil and gas operations, helping to maintain safety, protect assets, and improve production efficiency.

Gauge adapters with a female ISO parallel thread to male NPT are small but essential components used to connect measurement instruments, such as pressure gauges or transmitters, to piping systems in industrial and oil and gas applications.

The female ISO thread screws directly onto the instrument, while the male NPT thread connects securely to the pipe or tube, creating a tight and leak-resistant connection.

These adapters are made from high-quality materials such as stainless steel or brass, which makes them durable and resistant to corrosion, even in harsh environments. They are designed to handle high pressures, up to 10,000 PSI, ensuring that instruments provide accurate readings without risk of failure.

They follow international thread standards including ASME B1.20.1, SAE AS71051, ISO 7-1, and ISO 228, which guarantees compatibility with other equipment and ensures reliable performance in critical systems. This makes them a practical and dependable choice for monitoring and controlling fluids.

The Gauge Root Bleed Valve with vent tube and handle is a high-pressure valve designed to provide safe venting and pressure release in industrial and oil and gas systems. It is typically installed in high-pressure piping where pressure gauges or instruments are connected, allowing operators to isolate and safely bleed off pressure for maintenance, calibration, or inspection. The vent tube directs released media away from the operator, reducing the risk of injury or contamination, while the handle provides easy and precise manual operation.

This valve is rated for 6000 PSI standard working pressure, with higher pressures available on request, and is constructed with a metal-to-metal body and bonnet seal for reliable sealing at high temperatures and pressures. It features a backseat stem for added security, a self-centering, non-rotating tip to ensure leak-free performance, and a simple adjustable gland retainer to maintain packing stability over time.

Factory testing includes pneumatic tests with nitrogen at 1000 PSI to verify seat and packing integrity, with a maximum allowable leak rate of 0.1 sec/min. The valve materials can be supplied in stainless steel or other corrosion-resistant alloys and are compatible with NACE MR 01-75 standards. Heat code traceability ensures quality control and material verification for critical applications.

This valve is essential for safely isolating and venting pressure from instruments, gauges, or process line.

The HDI 2250 Valve Position Indicator System provides a reliable method to monitor the open or closed status of manual and hydraulically operated gate valves on choke manifolds. It offers two modes of position verification: a clear visual indicator mounted directly on the valve, and an electronic signal transmitted remotely to control rooms or monitoring systems. This dual feedback delivers real-time valve position information both locally and from a distance, enhancing operational control and safety.

The system is compatible with a wide range of rising and non-rising stem gate valves from various manufacturers, adding position monitoring without compromising valve integrity or certification. An adapter enables installation on valves that lack built-in position feedback. The sensor is an inductive Namur type housed within a rugged 316 stainless steel case, engineered for hazardous oilfield environments. It operates on a 5 to 25 volts DC power supply, making it suitable for integration with most industrial control systems.
