FIRE DETECTORS- SIL 2

FLAME DETECTION

The main feature that must be looking for is the reliability of the detectors, therefore avoid the false alarm must be the goal. For that reason, existing UV sensors and IR sensors, and they are monitoring the wavelength outside of range of the sun solar to avoid be triggered when the sun goes directly to the sensor. Other point the fire has a wide composition of wavelength, it goes since UV until IR, therefore the manufacturers design a composition of several sensors and different types and an algorithm where only the combination of the IR and UV Sensors are activated. It is recommended that the detector has at least two Infrared detectors to detect the flicker of the flame, because only one can be misled and generate a false alarm.

That is the reason which recommend to use a Fire Detectors with different Sensors Technologies (UV-IR) to cover the range out the Solar wavelength of the flame and at least two Infrared sensors with different wavelength, in this way the risk of false alarm is deeply reduced. It is very important that the detectors must self-diagnostic type and at least SIL 2 approval

GAS DETECTION

For the Gas Detection, one of the features most important of the sensors of the gas detectors is the precision and reliabilty. There are two main technologies:

1-Catalytic Bead: A small coil wire of Platinum is covered for a layer catalytic which reacts in presence of Hydrocarbon Gas increasing the temperature and changing the electrical resistance, this element is placed in a Bridge Wheatstone and unbalanced will be proportional to amount of hydrocarbon gas. We found some information done by specialists of General Monitors (Dr. Shankar Baliga, Ph.D. in Physics from Ohio State University) indicating:

“Although catalytic bead sensors have been in use for decades, the technology has some drawbacks. One critical limitation is the inability to operate in an environment deficient in oxygen since the bead requires efficient oxidation of hydrocarbon gas; oxygen levels impact oxidation efficiency; and hence, the sensor’s accuracy. Another drawback is the possibility of sensor poisoning by chemical compounds such as silicones and sulfur compounds leading to a decline in catalytic activity. Contamination of the sensor is also possible, for example, by trapping of dust in the flame arrestor or exposure to heavy oils and greases. Contamination can show up during normal maintenance of the system as an increase in the response time to calibration, recovery time after exposure, and loss of sensitivity.

Since these conditions can occur without warning to the operator, electro-catalytic hydrocarbon sensors are not fail-to-safe; fail-to-safe in this instance implies the sensor’s ability to communicate its dysfunctional status to the operator for the various failure modes. For example, the operator may not know the poisoned status of the catalytic bead until calibration gas is required. This results in an increase in calibration intervals in areas where poisoning agents are suspected to exist”.

2-Infrared: It : It is required an infrared emitter and Infrared receptor, The Hydrocarbon Gas absorbs the Infrared energy, The IR method of measuring gas concentration is based on the absorption of IR radiation at certain wavelengths as the radiation passes through a volume of the gas. IR gas sensing technology provides for fail-to-safe operation in contrast to electro-catalytic sensors since optical sensing is an active technology, which continuously monitors for sensor faults and communicates them to the user.

This is achieved chiefly through the use of the second or reference wavelength. IR detectors are also immune to poisoning, resistant to corrosion, can operate in a deficit or surplus of oxygen, and do not suffer from reduction in sensor life on repeated exposure to gas. With the sophisticated optical and electronic designs currently being used, the detectors are factory calibrated and virtually maintenance free. This is particularly desirable when sensors must be located in inaccessible areas and cannot be easily calibrated on a periodic basis.

GAS DETECTION

TexPetrol, Inc. uses infrared for Gas Detection for the reliability and precision. The infrared gas detectors used by Texpetrol differ from all other models, because they utilize silicon based solid-state infrared sources. The complete opto-mechanical design and construction is so stable that an ultra-fast speed of response can be achieved whilst providing unparalleled service life and detector stability, thus saving on maintenance and service costs. It is very important that the detectors must self-diagnostic type and at least SIL 2 approval For retrofit applications, a bridge interface is available allowing the detector to be connected directly to catalytic systems, using the existing cabling and control modules.”

SIRENS, HORNS, BELL, SOUNDERS ALARMS

For Fire and Gas Detection System the Sound Alarm is very important to avoid the losing of life, this signal is vital for the operator in the field. One of the most important features the customer needs to be aware is the sound level, we need the sound emitted by device must be superior than the noise in the industrial environment where the operators would be working.

The material must be done to avoid corrosion and the capability to be submitted for supervision and monitoring. If the device is not SIL 2, It would be necessary to increase the amount of testing to check the good performance. A certify specialist in Safety Instrument Systems could indicate the number of testing required for the system to keep the SIL 2 Level. We have a variety of options to be installed in Electrical Classification Area Class I - Div.2, Class 1 - Div. 1 or Harsh Industrial Environment as General Purpose.
