All Yokogawa pressure transmitters are designed and certified to IEC61508:2010 Parts 1 through 7 and IEC61511:2004 Parts 1 through 3. They are certified for single transmitter use in SIL 2 safety applications and dual transmitter use in SIL 3 safety applications with no special option required. With Yokogawa’s transmitters, no longer will you have to maintain two seperate inventories – one for production applications and one for safety applications. Diaphragm Seal System can provide the solution. For measurement of:

high/low temperature fluids
highly corrosive/high viscosity fluids
the fluids which may cause clogging of impulse piping in the low temperature
toxic fluids
Various process connection size
