Statox 560

Product catalog summary

Overview: The Statox 560 is a stationary gas detector designed by COMPUR Monitors GmbH & Co. KG for detecting toxic gases. It features an automatic self-test mechanism to ensure reliability and compliance with SIL 2 safety standards.

Specifications: The device operates on a 24 VDC power supply, with a power consumption of up to 2.7 W. It functions effectively within a temperature range of -30°C to +60°C and a pressure range of 700 to 1300 hPa. The detector is explosion-proof and has an IP66 protection class.

Functional Safety: The Statox 560 complies with SIL 2 standards, ensuring a low probability of failure on demand (pfd) and a high safe failure fraction (sff). This compliance is achieved through high-quality components and rigorous testing routines.

Self-Test Mechanism: The detector performs automatic self-tests at programmable intervals. During the test, a gas generator produces a small amount of target gas, which is fed to the sensor by a micro pump. The sensor's response is monitored, and if it fails to respond, a system failure or maintenance request signal is sent to the control room.

Construction and Operation: The Statox 560 consists of a sensor head, control module, alarm module, and power supply. It uses the Statox 505 sensor family, which stores important parameters in F-RAM. The system can operate as a standalone unit or be integrated into a larger detection system.

Technical Data: The detector supports gases like Phosgene (COCl2), Chlorine (Cl2), Hydrogen cyanide (HCN), and Hydrogen sulphide (H2S), among others. It transmits data as a 4-20 mA analog signal and features open-drain outputs for alarms and maintenance requests.

Advantages: The Statox 560 provides reliable gas detection with minimal maintenance, offering peace of mind and cost savings. It allows for easy replacement of sensor modules and can be calibrated in the field if necessary.

Manufacturer Information: COMPUR Monitors GmbH & Co. KG is based in Munich, Germany. Contact details and further information are available on their website.

Why Self Test? The everyday reading on a gas detector is “zero”. Most industrial plants operate in normally gas – free atmosphere. It is vital that unusual conditions cannot go un noticed. As a rule, a zero reading can always be caused by two reasons, either the gas concentration is really zero, or the gas detector has failed. Functional Safety Gas detectors designed to ensure worker safety, is selected to comply with functional safety standards. These are rated in SIL levels (SIL = safety integrity level). This level depends on the pfd(= probability of failure on demand) and the sff (= safe...

How the self - test works In programmable time intervals the following procedure starts: The sensor head activates a gas generator. This generator produces a tiny amount of the target gas. A micro pump feeds this gas in front of the sensor. Now the sensor must respond within a certain time window to the gas present. As soon as the signal is within specifications, the gas generator switches off, and the system is purged until the signal is zero. This self – test takes less than 2 minutes. Of course the test does not start, when gas is present in the surrounding air, or other environmental parameters...
