The HDI 1000B Pressure Gauge System is an intrinsically safe, battery-powered, solid-state electronic pressure gauge designed for accurate and reliable pressure measurement in demanding industrial environments. It measures pressures ranging from 30 psi up to 20,000 psi with an accuracy of ±0.50% of full scale. The system features a durable design with no fluids or moving parts, reducing maintenance requirements and improving long-term reliability.

The gauge includes a clear liquid crystal display (LCD) that combines a five-digit numeric readout for precise pressure values with a 101-segment analog bar graph for quick trend visualization. The display is easily readable in various lighting conditions and includes a low battery indicator to ensure continuous operation.

The 1000B system is modular, comprising a gauge display, inline cable, and sensor assembly. This design allows the display to be positioned close to or remotely from the pressure measurement point, providing flexibility in installation. The system supports multiple connection types including 2” Male NPT, 2” 1502, 2” 2002/2202, or flanged connections to fit different piping standards.

Power is supplied by a replaceable internal 3.6 VDC battery pack, which typically lasts up to 18 months during continuous operation. The gauge system is designed to retain calibration and settings during battery changes or power interruptions, enhancing reliability in field use.

For integration with control systems, the 1000B offers optional 4-20 mA or 0-1 V outputs, enabling remote monitoring, data logging, or connection to PLCs and chart recorders. The system is built to withstand high vibration environments, making it suitable for offshore, drilling, and other heavy industrial applications.

Overall, the 1000B Pressure Gauge System provides a precise, low-maintenance, and versatile solution for pressure measurement needs where safety, accuracy, and durability are critical.

The 2 Valve Manifold T Type – Pipe to Flange 1/2” Female NPT is designed to provide a reliable and compact solution for connecting impulse lines to pressure transmitters and gauges. This manifold allows operators to safely isolate instruments from the process for maintenance, calibration, or testing, without the need to shut down the system. The T-type configuration features two valves that control flow to and from the instrument, enabling efficient block, bleed, and vent operations.

The pipe-to-pipe design ensures a direct connection to the piping system, which reduces potential leak points and simplifies installation. It is suitable for high-pressure applications, with a standard working pressure of 6000 PSI and options available for higher pressures. The manifold is built with a metal-to-metal body and bonnet seal for enhanced durability and temperature resistance, with materials that can comply with NACE MR 01 75 standards for corrosion resistance.

Additional features include a removable T-handle for low-torque operation, self-centering non-rotating stems for consistent shutoff, and a dust cap to prevent contamination. Packing is positioned below the stem threads to isolate the threads from the process media, and the stem’s rolled threads provide smooth operation and long life. The manifold is 100% factory tested for leakage and performance, ensuring reliable operation in critical oil and gas applications.

Hex Reducing Nipples Male NPT are pipe fittings designed to connect two female-threaded pipes of different diameters while maintaining a secure and leak-resistant seal. The male tapered threads provide a tight connection that prevents fluid leakage, which is especially important in high-pressure systems.

These fittings are widely used in the oil and gas industry, chemical processing, and instrumentation applications where a reduction in pipe size is required without adding extra joints.

They are manufactured from high-quality materials such as stainless steel, brass, and other compatible alloys, ensuring durability and resistance to corrosion. The fittings are precision-machined from bar stock to provide burr-free internal surfaces for smooth flow and to reduce turbulence within the system. Threads are carefully capped and packed to prevent damage during transit.

Hex Reducing Nipples are rated for pressures up to 10,000 PSI and comply with ASME B1.20.1, SAE AS71051, ISO 7-1, and ISO 228 standards. They are designed for reliable performance in ambient temperatures from -28 to 37°C (-20 to 100°F) and support efficient installation with standard wrenches thanks to the hex shape, which allows secure tightening. These features make them suitable for high-pressure and instrumentation piping systems where both reliability and traceability are required.

The Gauge Root Valve Female x Female 1/4” NPT is a small but essential valve used to protect and control pressure instruments, like gauges and transmitters, in fluid or gas systems. Its female x female connection allows it to connect directly to two male-threaded fittings, making installation simple and reducing the risk of leaks.

This valve can handle pressures up to 6000 PSI and operates safely across a wide temperature range. The internal stem is designed with a back seat and the packing is placed below the threads, keeping the threads protected from the process media. A self-centering, non-rotating tip ensures a tight seal every time, preventing leaks.

It also features a removable “T” handle for easy turning with low effort, smooth rolled threads for long-lasting use, and a dust cap to prevent dirt or debris from entering the valve. Each valve is factory tested with nitrogen at 1000 PSI to ensure it seals correctly and operates reliably. This type of valve is ideal for isolating and protecting pressure instruments in chemical, oil and gas, and industrial processes.

Reducing adapters Female to Male NPT are used to connect pipes or instrumentation lines of different diameters in oil and gas systems. They allow a larger pipe or fitting to join with a smaller one without leaking, ensuring the flow of liquids or gases remains safe and controlled. These fittings are especially useful in situations where space is limited or existing piping needs to be adapted to new equipment.

They are made from high-quality materials such as stainless steel, brass, or carbon steel, which can handle pressures up to 10,000 PSI. The female NPT side threads internally to receive a male pipe, while the male NPT side threads externally to connect to a female fitting. This combination provides a secure, leak-resistant connection that is durable even under high pressure, vibration, or temperature changes.

Reducing adapters are widely used in oil and gas production, processing, and distribution systems.

They are ideal for connecting instrumentation, control systems, chemical injection lines, or any piping where size changes are required. Their compact design and simple installation make them a practical choice for engineers and technicians who need reliable connections in complex piping networks.
