Developing Technologies. Creating Solutions. Protecting People.
[ Into first place with safety ]
More than 114 years of experience and capability in comprehensive safety solutions have made MSA a modern and forward-looking company for the protection of people, facilities and the environment. With around 5,500 staff worldwide, and our own research and development centres in Pittsburgh, Pennsylvania and Berlin, Germany, MSA has become one of the leading suppliers of the most modern safety technologies: Today MSA is already the biggest name for personal protective equipment and gas measurement technology, offering the largest range of products worldwide.

[ Optimal total solutions ]
MSA is one of the few suppliers of permanent gas measurement technology that develops and manufactures a complete range of products and integrates them into system solutions. This is the only possible way to develop optimum systems that can meet all customer requirements at an excellent performance-price ratio – an unbeatable case for safety and flexibility. Whether stand-alone, or integrated into existing control and monitoring systems, MSA offers madeto-measure solutions.

[ “Efficient safety is our top priority.” ]
“On our drilling and production rigs, where several million dollars worth of oil is drilled and produced daily, safety in the event of failure is the single most important factor. Intelligent systems with over 600 sensors that monitor the on-going operation and care for the safety of people, the environment and the total facility, are indispensable. Only MSA offers me this type of security with the widest range of technologies – perfectly integrated into a single system.”

Sensors
[ Safety starts with the sensor ]
Sensors play a vitally important role in all gas detection systems. Effective sensing requires accurate, stable and fast-response sensors to achieve good quality and reliable signals. For this reason MSA manufactures and assembles its own sensors which ensures complete compatibility with the signal processing equipment. To achieve the best possible results, a very wide range of sensing technologies is necessary. Many of these technologies have been developed by MSA and are being continually improved to meet increasing market requirements.

Infrared [ Open Path & Point ]
Many gases absorb infrared light at certain wavelengths. The absorption spectrum is distinctive for each gas in question. Infrared Open Path and the Point Technology from MSA use electronicallymodulated IR radiation sources at two different wavelengths. One wavelength is typical for the gas to be measured, while there is no infrared absorption by atmospheric gases for the other wavelength. The signals from both detectors are electronically amplified and fed into a microprocessor that conditions the signals and produces an output signal proportional to the gas concentration.

Sensor Technologies
[ The complete bandwidth to choose from ]
PID [ PhotoIonization Detection ] EChem

The gas sample is drawn into the measuring chamber by an integral pump and ionized by UV light. The ionization potential of the UV light is a specific value for the gas of interest. Gas molecules are separated into ions [RH+] and electrons [e–]. Subjected to an electrical field, they move to the electrodes. A current is generated and is transformed into a signal proportional to the concentration of the gas.

Electrochemical sensors are typically used to detect toxic gases in the ppm range. Electrodes separated by electrolytes are enclosed in a small plastic housing and are connected to an external electronic circuit. Gas diffuses into the sensor through a permeable membrane and a small current is generated by an electrochemical reaction. Since the rate of gas entry into the sensor is controlled by diffusion of the gas through the permeable membrane, the current is proportional to the gas concentration.

Flame
A hydrocarbon flame contains a large amount of CO2 gas. This CO2 is selectively measured with an IR sensor at a wavelength of 4.2 µm and the thermal radiation is measured with a second IR sensor. The flicker frequency is measured with a third IR sensor, however, in order to prevent false alarms such as those caused by solar radiation. This design of the flame detector can detect a 30 x 30 cm pan fire at a distance of up to 60 metres within a cone of vision of 90° horizontally and 90° vertically.

Catalytics

Photo-acoustics

The measurement principle behind this technology is based on catalytic combustion of the measured gas or vapours in air up to the Lower Explosive Limit [LEL] of the gas. The sensor consists of a pair of matched elements [PELEMENTS], a detector and compensator. The detector comprises a coil of platinum wire inside a small bead of catalytic material. The compensator is similar but does not contain a catalyst and therefore does not respond to gas. Combustible gases are oxidised only on the detector element, where the heat generated increases its resistance, producing a signal proportional to the concentration of combustible gas. The compensator helps to compensate for changes in ambient temperature, pressure and humidity which affect both elements equally.

Photo-acoustic sensor technology was developed by MSA for the detection of toxic or combustible gases at very low concentrations. A gas sample is introduced into the measurement chamber and the sample is exposed to a specific wavelength of pulsed infrared light. If the sample contains the gas in question, it will absorb an amount of infrared light proportional to the concentration of gas present. The gas molecules heat and cool as they absorb the pulsed infrared energy. The pressure changes resulting from the heating and cooling of the molecules are measured by a sensitive microphone located inside the photo-acoustic infrared monitor.

Semi-conducters [ Solid-State-Sensor ]
Semi-conductor gas sensors are based on the electronic conductivity effects when gases are adsorbed onto a semi-conductor surface. Resistance changes in the semi-conductor material when exposed to gases other than air are converted into an electrical signal proportional to the concentration of the gas.

[ “Compact, flexible, convenient.” ]
“As refinery operators safety is our first priority. In our search for a compact, flexible and convenient system, all paths led us to MSA. The SUPREMA fire and gas control system offers us maximum safety with maximum flexibility. Individually configured to our safety requirements and expandable as necessary. A single system – with a thousand options to match our various needs.”

SUPREMA
[ Safety from a central perspective ]
Highest safety standard requirements and forwardlooking technology were the benchmarks for development of SUPREMA, the safety control centre from MSA. Digital bus technology guarantees absolute reliability and the simple implementation of a very wide range of alarm system concepts. With the open collector driver outputs, relays or other switching units can be controlled directly.

[ Made-to-measure safety ]
SUPREMA is Number 1 in made-to-measure safety for all types of demands and sizes of facilities. The scalability and the minimal amount of cabling required by the decentralised configuration enable costefficient implementation and ensure high availability.

[ “Everything fits together.” ]
“Our paper factory has grown steadily in recent years. It was particularly important for us to find safety systems that could be easily expanded and thus grow with us. A small System 9020 was initially sufficient for our needs. In the course of time, our requirements have grown. We have switched to SUPREMA, added ULTIMA X for combustible gases and FlameGard for reliable flame detection. Everything has functioned perfectly – everything just fits together.”
