Product overview
Field Instrument Surge Protective Devices is a device used to protect on-site instrument equipment from the impact of surges. In industrial control systems, sudden surges or electromagnetic interference may cause damage or malfunctions to instrument equipment, so the role of surge protectors is very important.
The intrinsically safe explosion-proof certification ensures that these devices can be safely operated in potentially explosive atmospheres, minimizing the risk of ignition and explosion. This certification is crucial for industries such as oil and gas, chemical processing, pharmaceuticals, and others where safety is paramount in hazardous environments.
