Gas leak detectors from MSR-Electronic can be used as integrated bus systems in buildings, garages, and industrial settings. These bus systems, essential to a building’s automation system, connect different devices to one another. The components in these devices utilize various communication channels to transmit sensor signals. A gas leak detector is also ideal for use within these bus systems.
The information flow follows standardized rules, facilitating cohesive operation among all components. Gas leak detectors are frequently incorporated into new buildings, contributing significantly to energy and resource conservation efforts.
What is a Bus System?
As mentioned above, a bus system connects various components to facilitate data transmission. This system coordinates the functions of connected devices, such as an alarm system, by linking consumers, sensors, and switches through a low-voltage cable.

To prevent data collisions, all components within the bus system must avoid simultaneous data transmission. Therefore, components should be configured to receive data only when relevant to the current transmission.
Bus system management is typically overseen either directly by the processor or by a dedicated bus controller. Each component is allocated specific time slots for communication, ensuring orderly data exchange.
What is the Difference?
Analog Signal (4-20 mA/2-10 V) vs Digital Bus Signal
Analog signals are often made up of intricate cable infrastructures and are also associated with additional costs due to these complexities. Moreover, analog signals can be more difficult to troubleshoot due to insufficient diagnostic information, making them more vulnerable to failures and processing inaccuracies.
To this end, a digital bus signal is the better choice as it comes with a variety of technical advantages.
Why a Digital Bus Signal?
- Additional functionality
- Cost efficiency for large-scale plants
- Fault notifications
- Faster troubleshooting due to the diagnostic information available
- Higher protection against third-party interference
- Less wiring effort
- Less space is required in the switch cabinet
- More secure against unwanted white noise
- Information and data are written and read remotely
- Maintenance intervals
Bus System – MSR-Electronic’s Approach
Gas leak detectors from MSR-Electronic, including PolyGard® and PolyXeta®, serve as integral components within bus systems deployed across diverse industrial projects. These projects encompass a spectrum of sectors, including the oil and gas, petrochemical, as well as modern buildings, garages, and laboratories.
These detectors are equipped with interfaces compatible with various building management systems, including Modbus RTU, Modbus TCP/IP, or BacNet. This compatibility empowers individual bus users to remotely access critical information such as measuring values, maintenance intervals, and fault notifications.

MSR-Electronic’s Approach to a Solution
The SC2 gas sensor from the PolyGard® series is used as a bus system in buildings, garages, and labs, while the SSAX1 and SX1 gas sensors from the PolyXeta® series are used in the industrial sector.
The intelligent digital sensor head SC2 is used to detect toxic, flammable gases, Freon gases, and refrigerants. This sensor includes an electronics system with an amplifier and a μcontroller for processing measurement values.
The μprocessor’s internal memory securely stores all relevant data and measurements from the gas sensor and transmits them digitally to the board (e.g., SB2) via MSR’s proprietary local bus. Maintenance of the device can be easily performed by either replacing the gas sensor or executing the integrated, user-friendly calibration routine directly on the plant.

The Bus System for PolyXeta® in Industrial ATEX Areas
In addition to the sensor element and amplifier, the SX1/SSAX1 digital sensor head includes a μcontroller for processing measurement values. This controller securely stores all relevant data and measurements from the gas sensor and digitally transmits them to the gas leak detector PX2/WSB2 board via the local bus.
The measurement value can be output as a PWM signal. Calibration management is also integrated into the sensor head’s μcontroller. Calibration is straightforward, achieved by either switching the sensor head or performing the integrated, convenient calibration routine directly on the plant.
