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 HDI 2000B Pressure Gauge System is a panel-mounted electronic device designed to measure and display high-pressure levels accurately in industrial and oilfield settings. It monitors pressures up to 20,000 psi with an accuracy of plus or minus 0.50 percent of full scale, making it suitable for critical applications where precise pressure monitoring is essential for safety and operational control.

The system consists of two main components: a digital gauge display and a remote pressure sensor connected by an interconnect cable. This design allows the sensor to be installed directly at the pressure source, such as a wellhead, pump, or manifold, while the display is mounted in a more accessible location for easy reading and monitoring.

The gauge features a six-inch liquid crystal display that combines a five-digit numeric readout with an analog bar graph composed of 101 segments. This clear and detailed display makes it easy to quickly understand both the exact pressure value and its trend, even in low-light or harsh environments. The display can be read from up to 35 feet away.

Power is supplied by a replaceable 3.6-volt battery designed to last between 12 and 18 months under continuous operation. Calibration and configuration data are stored in memory that does not require power, ensuring settings remain intact even when the battery is replaced or the system is powered off.

The pressure sensor employs strain gauge technology and is compatible with a wide range of connection types including standard pipe threads and flanges. This allows the system to be used across various equipment and pressure ranges, while simplifying maintenance by enabling cross-compatibility of sensors.

Optional analog outputs provide 4–20 mA or 0–1 volt signals to connect the gauge to control systems, data loggers, or remote displays. This supports centralized monitoring and integration with automated process control.

In oil and gas operations, the 2000B system is commonly used to monitor pressure at wellheads to ensure safe extraction pressures, on pumps to maintain correct fluid flow and prevent overpressure damage, and on manifolds to track pressure differentials between flow lines. Accurate, real-time pressure data from this system helps operators detect anomalies early, avoid equipment failure, and optimize production rates while maintaining safe operating conditions. Its robust design and modular installation make it well-suited for harsh field environments where reliability and ease of maintenance are critical.

Hex Body Needle Valves Female x Female are precision valves designed for accurate flow control and isolation in piping systems. The hexagonal body allows for easy installation and secure tightening using a standard wrench. Both ends have female threads, enabling direct connection to male-threaded pipes or fittings without additional adapters.

These valves are suitable for high-pressure and high-temperature applications, with a standard working pressure of 6000 psi and temperature ratings from -50°C to 230°C, extendable up to 500°C with graphite. They are commonly used in oil and gas, instrumentation, and process control systems to regulate fluid or gas flow, perform system bleed operations, or isolate sections of a pipeline.

The valves feature a metal-to-metal body and bonnet seal for durability, a self-centering non-rotating stem tip for consistent shutoff, and packing located below the threads to prevent process media from reaching the threads. Factory-tested for seat and packing leakage, these valves provide reliable, leak-free performance in demanding environments.

The 1/2" poppet type check valve with male × female NPT connections is designed to allow fluid flow in one direction while preventing backflow in oil and gas systems. Its poppet mechanism provides fast response and a positive seal under pressure, protecting pipelines, pumps, and equipment from reverse flow and pressure fluctuations.
