Pressure transmitter SIL-2
DST P92S
The DST P92S OEM pressure transmitter is
designed for use in Mobile and Industrial
hydraulic applications.
The transmitter is suitable for use in a functional
safety environment with a requirement of PLd,
EN ISO 13849-1: 2015 or AgPLd EN ISO 25119:
2010 or SIL2, IEC 61508:2010, respectively.
Further Danfoss holds a third party approval from
TÜV to ensure easy implementation into any
safety system.
