Simtronics is pleased to announce the put on the market of the GD1, a new generation of open path detector.
The GD1 innovates by creating a new standard of toxic gas detection. At the heart of the detector is a tuneable laser diode that eliminates environmental effects from sun, rain, and fog. The laser scans single absorption lines where there is no interference from other gases. This new technology constitutes an important progress with exceptional performances and a extreme reduced maintenance.
Unlike traditional methods for detecting H2S (MOS or EC cell), the GD1 needs no recalibration and can replace multiple standard detectors to cover the same risk. Compared to traditional detectors the GD1 offers:
• Faster detection
• Reduced maintenance
• A life calibration
• Fast acting
The GD1 is also available with a dual output gas configuration, Methane and Hydrogen Sulphide.
Supplied with worldwide hazardous area approvals. Suitable for use in SIL 2 systems.
With its level of detection lower than 5ppm and it is faster response time (T90 < 5 sec) the GD1 is ideal to ensure the personnel safety on petrochemical installations onshore or offshore or for the sites of treatment of waster water.
Furthermore, the GD1 offers real cost savings, using a single transmitter / receiver pair, the detector covers distances of up to 100 metres. Installation and maintenance costs are reduced as fewer devices are needed to cover the same risk as several point detectors.
As with all Simtronics’ products, the GD1 is designed for early detection of hazardous events. It’s built to work safely in extreme areas and withstand the hardest environments onshore and offshore.

The gas measuring systems for explosive gases and vapors made by J. Dittrich Elektronic determine the concentration of explosive gases and vapors in air in an ambient temperature from -10 to +50° C.
A pellistor or semiconductor sensor detects methane (CH4), hydrogen (H2), propane (C3H8), alcohol and benzine; additional hydrocarbons on request.
The calibration is carried out with the aid of the respective test gas by means of a potentiometer; however, a certain amount of cross-sensitivity of the sensor with regard to the other substances always remains.
Low-cost infrared measuring system for methane
Since the cross-sensitivity of the sensors gives rise to problems when monitoring methane, J. Dittrich Elektronic developed a new infrared measuring system which detects specifically methane quicker, more accurately and at less cost than conventional infrared systems.

Fastest warning for explosion hazards
With bright alarm LEDs and a loud buzzer the transmitter CC28 (ATEX) warns of combustible gases. This avoids expenses for additional Ex-proof buzzers and Ex-proof alarm lights and their costly wiring.
The improved sensor technology and a special „chimney effect“ make the CC28 the catalytic combustion transmitter for combustible gases with the shortest response time worldwide. The proven delta alarm of GfG’s GMA controllers reduces the response time even further – a very important feature particularly for handling explosion dangers. This gives the user important seconds to take counter measures or to get to safety.
Adjustments are done directly at the transmitter by means of touch keys (one man calibration) without opening the casing. An optional remote control facilitates inspection, service and calibration considerably, e.g. if the transmitter is mounted close to the ceiling; you do not have to climb up a ladder.
The gas concentration can be read directly at the transmitter, at the remote control and at the controller. Alternatively you may decide for a low-cost model of the CC28 without display or alarm.

The effectiveness of SIMTRONICS remote detectors (accuracy, fast response time and high reliability) guarantees the ultimate protection against the risks associated with gases in industrial environments.
The housings are given a special surface treatment to improve their resistance to corrosion (stainless steel or aluminium housings).
The measurement process is based on OXYCOL™ low temperature catalytic oxidation, enabling detection of all combustible gases and gives the detector an extremely long lifetime.
All the explosimeters are equipped with :
• An exclusive system of alarm verification in case of scale overrun,
• A linear response,
• A high stability,
• A very short response time.
The interchangeable and removable cartridges (as well as the support independent from the electronic box) make the remote detector easy to use and maintain.
All commands, configurations and readouts are remotely accessible using the infrared remote controller.

The Guardian range of infrared gas monitors offers near-analyser quality
continuous sampling, measurement and display of target gas concentrations at an attractive price.
The Guardian SP is a high accuracy monitor offering increased short term stability in lower ranges than Guardian plus models.
For many years, Edinburgh Sensors has pioneered novel non-dispersive infra-red dual wavelength sensors with a single optical path and without moving parts. This ensures long term stability, without the need for frequent re-calibration and makes the sensor highly gas specific and insensitive to other gases or water vapour.
The Guardian plus uses a robust infra-red source, proven in the Gascard II sensor, to ensure long lifetime and reduced susceptibility to shock. The reliability is further enhanced by the elimination of all moving parts from the sensor head.
The Guardian SP is easily maintained requiring only a few minutes per year to replace the hydrophobic particle filter in the inlet housing and a simple calibration procedure to check the accuracy, typically once a year. Applications include plant physiology, horticulture, fruit storage, leak detection, landfill, ventilation control, process control, furnace applications.
The Guardian SP includes an internal pump, liquid crystal display and temperature correction. It also offers a range of user-selectable bit-switches to control the latching alarms and analogue output options. The input power to the unit is user selectable to cover world-wide voltage and frequency standards.

For toxic gases, oxygen and hydrogen
Flexibly and surely
Where gas hazards are found, the proven EC24 is an optimal solution for the safe monitoring of rooms and plant areas. ATEX-certified construction also ensures safe operation even in hazardous areas containing flammable risks.
External sensor option
As an option, the sensor can be installed separately from the transmitter. This means that the sensor can be positioned in the dangerous area, and the transmitter installed and adjusted in a safe area.
The EC24 uses plug-in electrochemical sensors which are highly selective. This minimises the chance for false alarms to occur. Integrated electronics provide safe transmission of the measuring signal to the control unit. Potentiometers and measuring contacts behind a service flap enable convenient one-man calibration directly at the device.

Gas detection : O2, H2S, NH3, CO, NO, NO2, H2, SO2, Cl2, HCl, HCN…
The modern technologies used offer a high resistance to the humidity and temperature compensation as well as stability over time. In order to meet every requirement, SIMRAD Optronics ICARE proposes two different detection technologies :
• Electrochemical cells enabling a wide detection range and excellent selectivity.
• Semi-conductor cells providing extended detector lifetime.
The interchangeable and removable cartridge along with the wall mounting,
independent from the electronic housing, make this detector particularly simple to use.
• NH3 detection, low temperature
To meet needs of cold chains, a low temperature version enables detection down to -40°C.

Dräger's product range covers a wide variety of types: catalytic bead or infra-red IR sensor technology point or open path detection increased safety, intrinsically safe or explosion proof analog 4 to 20 mA, digital HART or RS 485 signal output with or without local display with or without on-board relays low budget or high end equipment Your local representative will gladly help you determine the right product for your application
Based on patented innovations, the Dräger PIR 7000 combines maximum light-efficient optics with a signal-stabilizing 4 beam technology. The double-compensating construction is characterized by the greatest possible robustness towards interferences (e.g. dust and dirt deposits). Due to its non-imaging nature, the measuring signal of the Dräger PIR 7000 remains unaffected by a partially covered beam. It can thus be ensured that the instrument fully complies with the requirement "no false alarms" .
