The internal electronics are protected by a gasket seal to prevent dust and moisture ingress, maintaining performance and longevity.

Installation flexibility is enhanced through support for cable lengths up to 1,500 feet, allowing the gauge to be mounted in the most accessible or secure locations. Multiple sensor housing options and connector orientations simplify field installation and reduce the need for onsite customization, helping to minimize downtime and installation costs.

The 1522 Choke Position Indicator System delivers accurate, real-time choke valve position information in a robust, easy-to-install package. Its reliable performance, flexible integration capabilities, and low maintenance design support improved flow control, safer operations, and optimized production.

The HDI 3200 MGS Differential Monitoring System is a battery-powered, stand-alone device designed to monitor critical pressures and temperature in Mud Gas Separator operations within oil and gas drilling environments. It measures and displays the differential pressure between the liquid seal and mud gas pressure, along with monitoring the mud temperature. These measurements are essential for maintaining safe and efficient separator function, ensuring proper gas-liquid separation, and preventing equipment damage or hazardous conditions.

The system uses accurate and reliable pressure and temperature gauges, with pressure readings displayed in 1 PSI increments. It supports alternate engineering units to meet user preferences or site requirements and provides a 4-20mA output for integration with local or remote monitoring and control systems.

The enclosure is made of a durable polycarbonate/PBT alloy that is impact-resistant and UV stabilized, suitable for harsh field conditions including exposure to sunlight, moisture, and rough handling. Its compact, modular design allows for easy installation and maintenance.

The 3200 MGS Differential Monitoring System is essential in drilling operations for continuously monitoring pressure differences and temperature within Mud Gas Separators. This helps ensure the separator is functioning correctly by preventing gas or liquid buildup that could lead to equipment damage or unsafe conditions. By providing real-time data, the system supports safer drilling processes, reduces downtime, and helps maintain optimal performance in challenging well conditions.

Hex Couplings Female NPT are pipe fittings designed to join two male threaded pipes in fluid and gas systems. The female NPT threads provide a tight seal when screwed onto male pipes, ensuring leak-resistant connections. The hexagonal shape allows easy tightening or removal using a wrench, making installation straightforward even in compact spaces.

These fittings are commonly used in oil and gas and process control applications. They are suitable for high-pressure systems, with pressure ratings up to 10000 PSI depending on the material. Hex couplings are available in stainless steel, brass, and carbon steel, offering durability and corrosion resistance in demanding environments.
