Erich Ott´s new safety limiter EX HS STB for DIN rail mounting in measuring stations and control rooms offers safe temperature limitation according to EG 94/9 for Ex zones I and II.
The compact unit ensures the safe temperature monitoring and limitation of electrically heated conduits, containers, tanks and apparatus in zone 1, and it is SIL 2 certified according to EN 61508:2001 (functional safety).
„We are proud to offer our customers this new product with real SIL 2 certification. In the market you also find devices of the same kind with proprietary SIL labeling. Yet, to ensure safe operation, it is absolutely necessary that limiters offer the proper safety level. Erich Ott has been in the industry for more than 40 years, and our customers can be sure to receive both high-quality products and honest advice for their deployments in hazardous locations“, says Carsten Ott, General Manager at Erich Ott.
All functions can directly be read off the limiter´s user-friendly illuminated triple-spaced display that shows an entire summary of the operational state. The limiter can completely be configured on-site, and both its simple parametrization and easy DIN rail mounting speed up deployment. Moreover, the limiter has a remote stop function.
The control unit has a single channel design and measures the temperature with a PT-100 sensor with three-wire connection. Depending on the temperature at the sensor and the nominal value the relay switches redundantly at the limiter´s output.
The limiter is EMC compliant according to EN 61326-1 and EN 61326-3-1.
