Instrumentation & Controls

Shielded multi-conductor cables that carry low-level analog and digital signals between field instruments and control systems. Constructions include individually and overall shielded pairs, twisted pairs, and armored variants for direct-burial or tray routing.

Cable rated for digital fieldbus protocols such as FOUNDATION Fieldbus H1 and PROFIBUS, with controlled impedance and capacitance to preserve signal integrity over the network segment. Typically a single twisted, shielded pair with defined DC resistance per IEC 61158-2.

Instrumentation and control cables that maintain circuit integrity or limit flame spread during a fire, used for emergency shutdown, fire-and-gas, and safety-critical loops. Performance is defined against circuit-integrity and flame-propagation test standards such as IEC 60331 and IEC 60332.

Input/output boards and control hardware that digitize field signals and execute logic, including analog and discrete I/O cards and motor-control electronics. Examples include BLDC motor controllers and accelerometer modules used in monitoring and motion-control loops.

Devices that measure process and equipment variables and output standardized signals, including industrial accelerometers and depth-measurement sensors. Downhole and drilling instrumentation in this group is built to withstand high temperature, pressure, and shock.

DC-DC converters and regulated power supplies that provide stable, isolated voltage rails to field instruments, transmitters, and control electronics. Isolation and regulation protect sensitive measurement circuits from supply transients.

Housings, junction boxes, and barriers that shield field instrumentation from weather, mechanical damage, and explosive atmospheres. Enclosures for hazardous areas are certified to IEC/EN 60079 protection methods.

Services that verify and adjust instrument accuracy against traceable references, plus electrical construction and installation work. Includes loop checks, commissioning, and laboratory calibration performed under ISO/IEC 17025.
