Safety Fast, Reliable Detection of O2, H2S or CO
Draeger (Germany) is expanding its family of single gas detectors with the launch of the Draeger Pac 3500 and Draeger Pac 5500. Designed for personal protection and ideal for use in oil and gas, chemical, power generation, steel, water and other general industrial applications, these compact gas detectors measure the concentration of oxygen, carbon monoxide or hydrogen sulphide in the air. Both instruments use minimal battery power and, because they have low maintenance requirements, offer a low cost of ownership.
The Draeger Pac 3500 has a lifespan of approximately two years and the Draeger Pac 5500 has an indefinite lifespan with proper maintenance and servicing. Both units feature the same powerful Draeger detection technology.
The integrated Draeger XXS sensors offer an expected lifespan of five to eight years. The same is true of the oxygen sensor, which operates consumption-free and has been produced lead-free. The triple electrode technology on which it is based has been patented and prevents early sensor wear. The battery and filter of the Draeger Pac 3500 can be replaced while the sensor does not have to be changed over the complete instrument life. The battery, sensor and filter of the Draeger Pac 5500 can be easily replaced without the need for special tools.
The Draeger Pac 3500 and the Draeger Pac 5500 allow the gas to enter the sensor from several directions. This reduces the risk of an accidentally covered inlet preventing access to the sensor for measurement. The sensors detect the gases quickly and reliably. When used to detect hydrogen sulphide, the instrument indicates measurements with one decimal point and, as a result, is ideal for low warning thresholds and reduced limit values.
Featuring a short response time, both instruments are quick to generate visual, acoustic and vibrating alarms during a hazardous situation.
Used to test instrument function, the Draeger Bump Test Station operates without a power supply. This means that the mandatory daily tests can be carried out on-site and without undue delay to the work process – even when large numbers of instruments are involved. The optional test for each instrument takes eight to fifteen seconds, ensuring quick, easy testing. The user- programmable bump test and calibration intervals mean that the detectors can be configured to stop automatically after an adjustable tolerance period if the user ignores the request for a bump test. The same applies to the (non-)observance of regular service and calibration intervals in the workshop.
Reader Reply Card No 191 New Micro Motion® Zirconium Fork Density Meter Emerson Process Management (UK) now offers its Micro Motion® 7826 Insertion Liquid Density and Concentration Meter in Zirconium for enhanced corrosion resistance.
The new Micro Motion Zirconium fork density and concentration meter is designed to monitor inorganic chemicals such as hydrochloric, nitric and sulphuric acid. The new meter is ideal for applications in the chemical and oil and gas industries, as well as clean in place (CIP) processes in the food and beverage sector.
The Micro Motion 7826 uses a vibrating fork to measure density and concentration and is ideally suited to continuous, real-time measurement and control in pipelines, bypass loops and
tanks. The Zirconium fork liquid density meter has the same form, fit and function of the existing fork density meter, offering an integral mount transmitter with two mA outputs and Modbus/RS- 485 communications. Approvals for the meter include ATEX and CSA/C-US.
The Micro Motion 7826 Zirconium fork density meter, installed in an application at Momentive Performance Materials, has delivered solid results in a process that produces hydrochloric acid, which is then reused in a chemical operation within the plant. “This process requires a device that can handle the critical control of HCl concentration while being easy to clean to avoid clogging,” explained Roger Knox, Momentive’s instrument technician. “The Micro Motion fork delivered as we’d hoped - good density measurement for process control and easy accessibility to all wetted parts.” The 7826 can be used in process control where density or concentration is the primary control parameter for the end product, or as an indicator of some other quality control parameter such as % solids.
Constructed to meet the most demanding process applications, the 7826 is a rugged and reliable direct insertion meter that requires very little maintenance, is insensitive to vibration, temperature and pressure variations, and provides high accuracy density and concentration measurement (± 0.001g/cm³ density, ±0.1% concentration). The unique direct insertion design gives unparalleled installation flexibility to provide fully integrated density measurement.
With the introduction of the Zirconium fork density meter, Emerson has completed its corrosion resistant range of world-leading Micro Motion 7826 density and concentration meters. The range is currently available in B3 and C22 Nickel alloys, Monel 400, Titanium and Stainless Steel construction. There is an image to accompany this release.
