Overspeed-protection

For monitoring critical rotating machines for overspeed and acceleration, Istec offers state of the art and reliable protection systems. The hardware is suitable for SIL 2 and SIL 3 applications and in accordance with API 670.


Why Istec?

The reliability of a protection system is crucial and starts with choosing the right hardware. We believe, however, that the quality of this hardware can only really express itself when good service is provided. That is why we offer lifetime support and turnaround service on both the systems we supply and systems from other brands. Thus we ensure the safe operation of rotating machines with maximum uptime and efficiency.


Complete monitoring systems

For monitoring on overspeed, we offer state-of-the-art systems that can be used for SIL2 and SIL 3 applications.

SpeedSys 200

The SpeedSys 200 is a high integrity overspeed protection system. The robust design with advanced self-monitoring, galvanic separated in- and outputs and certification by design make a high-end product that stands out in the market. The focus on the core safety functions make a system that is easy to use and to maintain, with very long proof test intervals. SIL 2 certified protection can be achieved with a single module but because of the versatility of the system, multiple modules can be linked to maximize availability.

Spare parts FT3000

The production of the FT3000 overspeed monitoring system has been discontinued since 2018 by TE Connectivity (formerly Jaquet). Istec offers spare parts for the system as long as they are in stock and continues to offer technical support to our high service standards to guarantee a reliable system.

Simple systems

For smaller speed measurements and monitoring without SIL requirements we offer a series of tachometers with programmable logic.

Proof tests with overspeed simulation

To validate a monitoring system, it is necessary to simulate an overspeed situation. Our specialists perform proof tests for this with the 3-channel frequency generator (IST-101) that we have developed.
