SIL Suitable Toxic Gas Detection

The global importance of SIL (Safety Integrity Levels) has grown substantially in the oil/gas, petrochemical and other process industries over the last 10 years. However, for many end users, systems integrators, and product vendors, SIL is still a somewhat ambiguous concept that often is misinterpreted and incorrectly implemented. In order to fully understand SIL and its implications, it is important to grasp the overarching concept known as Functional Safety, and how it applies to Safety Instrumented Systems (SIS) within the process industries.

To promote a better understanding of SIL and SIS, General Monitors has developed a special online SIL Resource Center. The resource center contains our Statement of SIL Conformity, a list of General Monitors SIL Suitable Products, SIL FAQs, Common SIL Myths, SIL Technical Articles and a list of useful SIL links.

SIL 2 Suitable TS4000 Toxic Gas Detector
The TS4000 Toxic Gas Detector has been third-party certified for SIL 2 applications and is approved by CSA, ATEX, CE Marking and GOST. With its sophisticated design, the TS4000 offers many advanced features, including long distance remote mounting up to 2,000 feet, dual redundant MODBUS communications, 8 Amp relays, three-digit display, 4-20 mA output, and an indication of remaining sensor life.

The TS4000 Detector provides complete status and control capability in the control room. Additionally, the interface module’s galvanically-isolated, intrinsically-safe design supports sensor field replacement without special tools or hot work permits. All electronics are contained within an explosion-proof housing so that sensor information can be processed at the sensor site.

Easy to install, the TS4000 features one-person calibration and can virtually self-calibrate by activating a magnetic switch and applying gas. Process engineers who need to protect people and equipment will find the TS4000 Toxic Gas Detector ideal for chemical, oil and gas, water and wastewater treatment, pulp and paper, and other hazardous environments. Additional applications include public utilities, refineries, pharmaceuticals, and food and beverage.

The TS4000 monitors a variety of toxic gases in the parts per million (ppm) range, including ammonia, carbon monoxide, chlorine, chlorine dioxide, hydrogen chloride, hydrogen sulfide, nitric oxide, nitrogen dioxide, oxygen, ozone, and sulfur dioxide. The system displays gas concentrations up to 500 ppm, fault codes for troubleshooting, prompts when calibration is needed, and provides complete status to the user. Additionally, the TS4000 simplifies operation and maintenance and reduces downtime by indicating remaining sensor life.

SIL 2 Suitable TS400 Toxic Gas Detector
The space-saving TS400 Toxic Gas Detector continuously monitors 10 common industrial gases in the ppm (parts per million) range and is one of the industry’s smallest packages offering highly reliable protection while offering ease of installation, lower maintenance and extended life.

The compact Model TS400 (1.75 in. diameter and 4.5 in. long) fits within the palm of your hand. It weighs only 8 oz and its smaller size allows fixed placement in crowded plant conditions where other larger detectors will not fit. In addition to SIL 2 suitability, the TS400 features universal product approvals including CSA, C-UL, UL, ATEX and CE Marking.

The Model TS400's innovative modular gas sensor design is based on electrochemical cell technology. The gases detected by the Model TS400 are: ammonia (0-50 ppm, 0-100 ppm), carbon monoxide (0 to 100 ppm, 0 to 500 ppm), chlorine (0 to 10 ppm), chlorine dioxide (0 to 3 ppm), hydrogen chloride (0 to 20 ppm), hydrogen sulfide (0 to 100 ppm), nitric oxide (0 to 100 ppm), nitrogen dioxide (0 to 20 ppm), ozone (0 to 1 ppm), and sulfur dioxide (0 to 20 ppm).

With its built-in LCD indicator on the detector itself or with the optional field mounted display, the Model TS400 continuously monitors for (and displays) fault conditions, calibration and data memory errors. The advanced adjustment free calibration design reduces maintenance costs over the life of this detector.

Surface-mount transmitter electronics are contained in a lightweight, corrosion-resistant polypropylene housing in order to process all information locally. The TS400 provides a linear 4-20mA analog output signal that easily connects to control hardware, such as PLCs or computer-based systems. The two-wire loop powered design reduces installation costs.

The TS400's optional field mounted display makes local visual readout easy, providing additional safety monitoring for employees or equipment. With its heavy-duty industrial package, the TS400 is ideal in the harsh operating environments found in chemical processing, water or wastewater treatment, pulp and paper, electronics, food and beverage, electric utilities, pharmaceuticals, textiles, and more.
