Gas detection system Compur Statox 505 complies with SIL 2 Standard

The new 4 – 20 mA Transmitter Statox 505 for toxic gases and oxygen features everything that a new gas detection instrument generation needs: State of the Art components (hardware and software), smart sensor technology, “heartbeat” sensor control, complete system diagnostics on board. It features sensors for AsH₃, Cl₂, ClO₂, CO, COCl₂, H₂S, HCl, HCN, NH₃, N₂H₄, NO₂, O₂, O₃, PH₃, SO₂.

What makes the Statox 505 so reliable?

In process monitoring, the status of plant components in case of a failure is becoming more and more a critical issue. The standards DIN EN 61508 as well as the product standard DIN EN 50402 are powerful tools to calculate the probability of a failure on demand. The Statox 505 complies with the requirements of these standards. It obtained the safety integrity level SIL 2 applying DIN EN 50402.

This provides a reliable database for the user to calculate the safety standard of his plant. If the Statox 505 is operated as a SIL 2 component, a so called “proof test” in certain time intervals is mandatory.

All OK

All important parameters such as sensor „heartbeat“, signal output, calibration, zero, sensitivity, temperature, sensor memory, amplifier, CPU, power supply etc. are continuously monitored for proper function. In case of a failure, an alarm will be triggered. Thus the system cannot fail without the error being noticed. A green LED signalizes the system status. The display and the controls are located at the inside of the housing and well protected from the elements.

Minimum time and work in the field

The sensors of the Statox 505 are plug and play technology. Each sensor has a F -RAM on board which communicates all relevant parameters to the sensor head: gas, measuring range, last calibration, ex works calibration, response time etc.

The sensors can be easily calibrated in the shop. For the user this means that he never ever will have to do calibration work in the harsh elements (wind, rain, cold, heat). No more lugging heavy test equipment and gas cylinders into the field. All the user has to do in the field, is plug the sensor back in. To do that, you don`t even need a tool! While the sensor is getting his calibration in the shop, the sensor cartridge stays in place and protects the sensor head from dust and rain. This way the operator will always find a clean and functional display and keyboard on site.
