The HDI 2021 Pressure Transmitter System is an electronic device designed to measure pressure accurately and convert it into a standardized 4–20 mA electrical signal for monitoring and control. It consists of a strain gauge sensor embedded in a stainless-steel housing and a transmitter assembly that processes the sensor signal. This system is widely used in oil and gas operations to provide precise, real-time pressure data essential for safe and efficient wellhead monitoring, pump and compressor control, manifold pressure tracking, and other critical process points.

In typical oilfield applications, the transmitter measures pressure at locations such as wellheads, flowlines, separators, and pumps to ensure that equipment operates within safe pressure limits, preventing failures and optimizing production. The 4–20 mA output enables easy integration with control systems, remote displays, data loggers, and automated safety shutdowns, supporting operational decisions and regulatory compliance.

The 2021 system supports pressure ranges from 5,000 psi to 20,000 psi, with overpressure protection allowing up to 30% above rated pressure for lower ranges, and 10% for higher ranges. It offers multiple housing options including hammer unions and various flanged connections to fit existing infrastructure. 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.

The HDI 9000 Choke Console System is an independently powered control console designed for critical well control operations in oil and gas drilling. It integrates multiple individual electronic gauge systems to provide precise monitoring of key parameters such as choke position, pump strokes, pressure, temperature, and mud gas separator status. This modular system typically includes pressure gauges, choke position indicators, pump stroke counters, mud gas separator monitors, and temperature gauges, all operating on a common platform.

Powered by an internal battery pack, the 9000 Console operates independently from rig power, ensuring reliable performance even in power loss scenarios. The system is designed for harsh drilling environments, offering robust, intrinsically safe components housed in durable enclosures. Its modular nature allows customization to meet specific client requirements, including sensor types, communication outputs, and display configurations.

The console supports long cable runs—up to 1500 feet—to accommodate various rig layouts and sensor placements. Displays provide clear visibility from distances up to 50 feet, with low power consumption enabling battery life between 12 and 18 months under continuous operation. Maintenance is simplified through field-replaceable components and minimal calibration needs.

Overall, the 9000 Choke Console System enhances operational safety and efficiency by consolidating critical monitoring functions into a centralized, battery-powered, and customizable platform suitable for both land and offshore drilling environments.
