Impress Sensors & Systems is offering a range of temperature limiters/controllers, pressure transmitters, screw-in transmitters, submersible probes and level control switches, all with SIL2 (Safety Integrity Level 2) approval for hazardous environments.
The current SIL international safety standard provides suppliers and users with a common framework on which to design products and systems for safety related applications. The standard also provides a more scientific, numerical approach to specifying and designing safety systems, enabling the nature of the risk to be quantified. There are four safety levels, from SIL1 for low risks, to SIL4 for very high risks.
