In brief

Series 12 gauge and differential pressure instruments are distinguished by their AISI 316 stainless steel construction, small footprint, ease of adjustment, and excellent resistance to vibration and shock. The perfectly separated three-chamber construction makes them the best in terms of safety and compliance with explosion-proof regulations. Originally ATEX-compliant even in the free-wire version, they are also supplied with an aluminum or 316 stainless steel junction box and internal terminal block, so as to simplify the electrical connection. SIL approval then makes them suitable for use in Safety Instrumented Systems (SIS), offshore panel applications, rotating devices, firefighting systems, BOP storage systems and CO2 injection skids.
