Industrial systems widely use communication systems based on the RS-485 transmission standard. The serial nature of the RS-485 bus networks is the reason that a critical failure at any location of the network may disable communication within the entire system. Since Gas Safety Systems are very sensitive to perfect efficiency of communication, even potential, critical or probable failures of data bus lines may be really hazardous to safe operation of the system. It is why application of devices capable of isolating any defective fragment of the network, such as MOD SEP 2 modules, is beneficial and efficient.

The Control Unit Module Sigma MOD LED is a component of the Gas Safety System Sigma Gas. The module’s functions include i.a.: communication with gas detectors, control of visual and sound indicators and display of system status to the operator. Cooperate with Control Unit Module Sigma MOD DRV and Sigma MOD LCD it is possible to create a system dedicated for several alarm zones with a configuration dedicated to the customer's needs.

The gas mixtures are typically used to check operability of gas detectors and to calibrate their characteristic curves.

The ProGas 4 gas detector is specifically designed for critical functions such as measuring, monitoring and detecting hazardous gases in industrial installations.It can operate under harsh industrial conditions where environmental parameters may vary widely (high temperatures, mist and dust).

The ReAct 4 gas detector is specifically designed for critical functions such as measuring, monitoring and detecting reactive gases in the surrounding atmosphere, with particular emphasis on aggressive or corrosive atmospheres.

The SmArtGas 4 gas detector is specifically designed for critical functions such as measuring, monitoring and detecting hazardous gases. It is intended for operation in areas with potentially explosive atmospheres.

The Gas Sampling Point is a device that enables taking samples of ambient air from the monitored surrounding atmosphere with appropriate preparation of samples for further processing.

Service Cable CB6 is used to connect Sigma Gas with computer or another device with serial USB communication port

Signal Converter Sigma CNV ALHEAD is a device designed as part of the gas detection system Sigma Gas for the adaptation signal provided by Gas Sensing Probe Alhead 4 to Sigma Gas system. The signal converter is intended for use in potentially explosive atmospheres.
