In the context of electrical engineering, FSR can stand for Field Safety Representative, a role that requires certification in electrical technologies. FSR is also used to refer to force-sensing resistors, which are sensors that detect physical pressure, squeezing, and weight. These sensors are made of two layers separated by a spacer and their resistance changes as more pressure is applied.

FSR stands for Field Safety Representative in electrical certification
To become an FSR, one must obtain an FSR class A, B, or C certificate and be a qualified construction or industrial electrician. With this certification, an individual can apply for the designation of BC Master Electrician. The certification process ensures that electrical workers have the necessary knowledge and skills to safely perform their duties, protecting themselves and others from potential electrical hazards.
FSR certification is essential for electrical workers to legally perform their jobs and ensure safety compliance. It provides workers with the expertise to handle electrical installation, maintenance, and repair work, adhering to industry standards and best practices. The certification also empowers FSRs to make informed decisions regarding electrical permits, understanding who requires a permit, how to apply for one, and the process of amending work.
Additionally, FSR certification promotes the safe use of electrical equipment and systems. FSRs are equipped with the knowledge to identify and mitigate electrical hazards, ensuring that equipment is installed and operated correctly. They play a crucial role in preventing electrical accidents, reducing the risk of fires, shocks, and other electrical-related incidents.
Beyond the initial certification, ongoing education and training are vital for FSRs to stay updated with evolving electrical safety standards and technologies. Regular renewal of their certification ensures that FSRs maintain their proficiency and are informed about industry advancements, contributing to a safer working environment for all stakeholders involved.

FSR is also used to refer to Force-Sensing Resistors, which are thin sensors that detect physical pressure
FSR stands for Force-Sensing Resistors, which are thin sensors that detect physical pressure. They are made of a material whose resistance changes when force, pressure, or mechanical stress is applied. These resistors were invented and patented in 1977 by Franklin Eventoff, who founded Interlink Electronics in 1985 based on his invention. In 1987, Eventoff received the International IR 100 award for developing the FSR.
Force-sensing resistors are made of a conductive polymer that changes resistance when force is applied to its surface. They are supplied as a polymer sheet or ink that can be applied by screen printing. The sensing film consists of electrically conducting and non-conducting particles suspended in a matrix. When force is applied to the surface of the sensing film, the particles touch the conducting electrodes, changing the film's resistance.
FSRs are typically less than 0.5 mm thick, low cost, and have good shock resistance. They can be designed as single-point force sensors or in a matrix array form, allowing the capture of pressure distribution over a given area. FSRs have applications in many fields, including musical instruments, car occupancy sensors, artificial limbs, and foot pronation.
One example of an FSR is the FlexiForce sensor from Tekscan, which offers flexibility, operating capabilities, and the ability to function on simple circuitry. These sensors can be customized for shape, size, sensitivity, electrical termination, and operating temperature, making them suitable for embedding into smart devices with limited space and power constraints.

FSR can stand for Fuel Stroke Reference, which is related to fuel control valve stroke
FSR stands for Fuel Stroke Reference and is related to fuel control valve stroke. It is a value, represented as a percentage, of the amount of fuel that should be flowing to a unit through the openings in fuel control valves. FSR is widely considered to be equal to the gas control valve stroke (opening or position) when burning gas fuel. The gas control valve provides a fuel gas metering function to the turbine in accordance with its speed and load requirements. The position of the gas control valve is a linear function of the FSR generated by the SPEEDTRONIC control.
The FSR is related to the amount of energy flowing into the prime mover, which is also related to the speed of the prime mover and generator when they are not producing electrical power. For machines burning gas fuel, the gas control valve internals and fuel nozzle orifices are chosen so that the energy flow rate through the valve is proportional to the opening of the valve, or the "stroke" of the valve. The FSR can be used to determine the percentage of the rated power that a unit is producing. For example, when FSR is at 32%, the unit is producing approximately 36% of its rated power.
The FSR also plays a role in safety by providing a safety margin. Instead of the rated load occurring at 100% valve opening, the valve internals are chosen so that the valve will be at around 60-80% of rated travel when the unit is producing the rated load. This allows the valve to control the fuel flow rate if anything unexpected happens.
The gas fuel system, of which the gas control valve is a part, is designed to deliver gas fuel to the turbine combustion chambers at the proper pressure and flow rates to meet all the starting, acceleration, and loading requirements of gas turbine operation.

FSR is used on Mark IV, V, VI and VIe GE controls
FSR stands for Force-Sensing Resistor, a material whose resistance changes when force, pressure, or mechanical stress is applied. Force-sensing resistors were invented and patented in 1977 by Franklin Eventoff, who founded Interlink Electronics in 1985. FSRs are also known as force-sensitive resistors. They are supplied as a polymer sheet or ink that can be applied by screen printing. The sensing film consists of electrically conducting and non-conducting particles suspended in a matrix.
FSR is used on Mark IV, V, VI, and VIe GE controls. The GE Speedtronic Mark VI Gas Turbine Fundamentals and control basics include supply voltage, programming languages, and control modes such as start-up, speed, acceleration, temperature, and shut-down control. The 5-day training course on Mark VI covers the various GE Gas Turbine Systems and explains the operating requirements for Lube Oil, Hydraulic Oil, and Fuel Systems.
The GE Mark VIe Gas Turbine Startup also uses FSR levels during its startup sequence. The FSR (Fuel Stroke Reference) levels function from ZERO to MAX, and users can track real-time values using the ToolboxST block diagram editor. The detailed tutorial is essential for understanding how startup logic and fuel control work inside the SPEEDTRONIC Mark VIe system.
The 5-day operations and maintenance course is designed for personnel involved in the daily operations and maintenance of Mark V, Mark VI, and Mark VIe control systems. The course enables operators and technicians to configure HMI displays, manipulate HMI software tools, and diagnose problems in Gas Turbine SPEEDTRONIC Control Systems.
Overall, FSR is an essential component of the GE Speedtronic Mark series, providing valuable data on fuel stroke reference and control during the startup and operation of the gas turbine systems.
