Product description

DPharp is an active pressure sensor, so even with no pressure applied 

the resonators oscillate at theirnatural frequencies. Two independent 

resonators are utilized. If either one or both fail, the transmitter 

diagnostics detects a capsule error. DPharp sensor is inherently

 fail-safe with no undiscovered failure modes.


A patented reverse calculation algorithm validates internal 

measurements, calculations and detects any malfunction of 

the CPU.


DPharp transmitters are capable of SIL2 single use and SIL3 redundant

 use, as standard. Same transmitter can be used in control and safety

 applications which reduces spares inventory and simplifies maintenance.


Yokogawa transmitters have undergone complete assessment of 

hardware for SIL2 and development processes for SIL3 capability 

to IEC61508 safety standards.
