Difference between SIS, PLC and BPCS Systems
Safety Integrity Level (SIL) is a measure of safety system performance - not a measure of process risk. The higher the level of risk, the greater the system performance required.…
Why choose Intrinsic Safety ?
Intrinsic  safety (IS) is a low-energy  signalling  technique  that prevents explosions from occurring by ensuring that the energy transferred to a hazardous area is well below the energy required to initiate…
