The American Petroleum Institute, the governing body of offshore safety, requires all toxic gas detection devices to conform to the standard ISA92.0.01. As you design and update safety plans to protect offshore personnel, consider that requirement and the standard.

The Det-Tronics NTMOS hydrogen sulfide gas detector meets ISA92.0.01 and exceeds the directive in speed of response and environmental immunity. In addition, the detector’s high accuracy and stability coupled with speed of response have been proven in third-party performance testing. Tested in extreme temperatures and humidities, the NTMOS hydrogen sulfide gas detector is perfectly suited for harsh applications such as offshore oil exploration.

The open HART protocol improves the flow of diagnostic information from process instruments including optical flame detectors and combustible/toxic gas detectors.

User benefits of Det-Tronics HART-enabled flame detectors and gas detectors include faster commissioning and enhanced maintenance efficiency. Typical flame and/or gas detector configuration options accessible via HART communications include:

• Real-time clock setting
• Selection of calibration-gas types
• Zero and span gas calibration
• Optics cleanliness/optical integrity test information
• Custom descriptor information, such as installed date, by whom, where, and type of gas to be detected

For more information, please read this brief article written by Det-Tronics managers (Dave Opheim and John Jarvis) and recently published in PETRO Industry News. If you have any questions or comments, please contact us at rss@det-tronics.com .

Globally, safety standards play a key role in designing and executing gas and flame detection projects. These standards, which might seem cumbersome at times, can help engineers make informed decisions. The information in standards can be used to assist in maximizing safety.

In general, four classifications of standards are most relevant to flame and gas detection devices and systems:

- Hazardous Location
- Ingress Protection
- Performance
- Safety Integrity Level (SIL)

This brief paper , presented at last year’s ISA Analytic Division Symposium, can give some insight into using standards and certifications to improve safety.

On average, a person takes 12 breaths per minute. Given the deadliness of hydrogen sulfide (H₂S) gas, if a release occurs, an individual has a very few breaths – and a very few seconds – to get to safety. A gas detector that alerts people to the presence of H₂S gas in less than 5 seconds is essential.

Also essential: the gas detector must function as designed. The new Det-Tronics H₂S gas detector combines nanotechnology with a MOS sensor to achieve consistent speed (more…)

Hydrogen sulfide (H₂S) gas can cause nausea, headaches, unconsciousness, and death. Industries struggle to detect this deadly substance before it harms workers and communities. Safety system manufacturers have developed detectors that sense H₂S quickly and accurately.

Toxic gas detection technologies are advancing rapidly. In general, electrochemical sensors and metal oxide semiconductor (MOS) sensors are the current proven detection technologies. Recently, Det-Tronics has added nanotechnology (NT) to its MOS sensors.

The new NTMOS hydrogen sulfide detector has several benefits beyond standard MOS. It responds faster: T50 can be under five seconds. In addition, Det-Tronics NTMOS sensors operate over large temperature and humidity ranges.

When choosing hydrogen sulfide gas detectors, look for performance approvals that indicate the detector is fit for use and will do the job it’s supposed to. Det-Tronics has earned those approvals.

One of the gas detectors near a storage tank sends an alert that a leaking flange has burped out some methane gas. The event must be verified and the possible hazardous condition corrected. Quick access to event logs stored in the gas detector’s memory or in the safety system’s database can provide the information necessary to better understand the event and thereby ensure proper repairs.

A data log stored in a safety system, accessible by local or remote PC, provides critical information such as timestamp and location for all events. Similar information is available directly from many field devices. To retrieve the information, a HART Handheld device can be used. But that is not necessary. (more…)

Under day-to-day conditions, people cannot see, smell, or taste the presence of hydrogen gas. Hydrogen, however, is very flammable and requires only a small amount of energy to ignite. In fact, if leaking from a pipe at a high enough pressure, hydrogen gas can self ignite without the aid of an external energy source.

Working together, gas detectors and optical flame detectors can quickly identify a gas leak or the resulting flame.

For example, an enclosed battery room can contain hydrogen generated from the (more…)

You can choose the best available technology to sense hydrogen sulfide (H2S), but if your gas detectors are too few or incorrectly placed, they might never see the hazards and will not provide maximum protection.

How many gas detectors is enough and where should they sit? Experience, job-site analysis, and common sense help determine the answers. Consider the following factors for every installation: (more…)

When incorporated into flame detectors and gas detectors, the HART communication protocol enables efficient device set up, maintenance, and diagnostics.

Set up: Whether in the control room or in the field, users can configure or change device settings using a variety of tools -– Det-Tronics’ FlexVu® Universal Display, a HART communicator, or an asset management system.

Maintenance: Modifications to device settings are simple with HART protocol. By sending a single command, a user can perform many tasks such as reviewing logs or adjusting alarm and warning set points. In addition, a user can accurately assess device conditions (such as fault frequency) and prepare for tasks before venturing into the field.

Diagnostics: Automatically generated event logs present viewable history and possibilities for improvements. Time- and date-stamped records of activities such as calibration and device replacement provide regulatory-compliance evidence for system audits.

All of Det-Tronics X-Series flame detectors and many of its gas detectors are HART enabled. If you have questions, please contact us at RSS@det-tronics.com.

Errant industrial gases pose a dangerous mix of toxic and flammable hazards. To detect these hazards effectively, safety engineers must choose a gas detector that senses and measures the unique attributes of the target gas.

Following is a brief summary of several gas-detection technologies and the gas hazards they best detect:

Electrochemical technology is effective primarily for toxic gas detection. Electrochemical sensors use very (more…)
