Proof-testing of PCS safety instrumented systems, which usually takes place annually, is associated with considerable costs for plant operators. Flowmeters, for example, are often removed and recalibrated. The plant comes to a standstill and processes are interrupted. Added to this are the health risks posed by the possibility of personnel being present in the danger zone. All of this can be avoided with a reasonable level of investment! Intelligent proof test concepts and automated proof-testing eliminate the need for the costly annual proof test of safety instrumented systems (SIS).

Moderate investments in Functional Safety are sufficient to minimize random and systematic faults in plants. An efficient alternative to annual proof tests is offered by the HIMax safety controller (HIMA) in combination with Endress+Hauser's Heartbeat Technology. The HIMax always starts the automated testing at the optimal time of the plant process - without any dismantling and plant downtime! Error-free automated test results give you maximum plant availability.
Your benefit: Reduced risks, costs and enormous time savings.

Better safe than sorry: professional design, installation and commissioning of plants result in a reduction in systematic faults right from the start. Endress+Hauser supports you in the risk assessment and reduction of your plants and is your competent contact for all questions regarding Functional Safety. From the design and planning of SIS to project management and calculation of the safety loop, we offer all services from a single source.

With our Training and Seminars – digital or on-site, even individually at the customer's site - you will always stay up to date. You can rely on Endress+Hauser's instruments and services.

Digitalized industries are exposed to specific risks. Even plants with the highest level of functional safety are not automatically protected against cyberattacks. To protect your plants and process control systems from acts of sabotage or faults resulting from negligence, Endress+Hauser offer a holistic safety approach that successfully combines functional safety with the necessary cybersecurity. This reduces internal and external risks and ensures the availability of your plants.
