Optical humidity measuring explosion danger area
Humidity measurement is the key process control tool in many industries, there are a variety of technical solutions to choose from, each solution and each has its advantages and disadvantages.In combustible gas mixture and corrosive chemical measurement, the scope of applicable technology becomes more limited.Infrared (IR) within the scope of the optical wavelength humidity measurement has many attractive features.
Non-contact method to ensure safe and reliable
Measurement itself is a contact, because through the sapphire glass to protect the infrared light source and detector from process gas, thereby eliminating the sensors are corrosion problems.Measuring optical element in the design of the scene can be heated to eliminate condensation in 100% relative humidity environment.Light infrared light source and tunable method in - perot interference filter new progress makes the equipment upon the approval of the explosion-proof can be used for flammable gas persistent environment: European rules of 0 and 1 level 1 of the regulations of North America area.
New combination opportunity
Many will blast area of optical humidity measurement and measurement in the cross pipe configuration of expensive TDL laser.Based on 20 years of the new progress in pearl luo gan visits, now allows the use of a simple compact type probe NDIR device to measure water vapor.In addition, can now be humidity measurement combined with other gases such as methane and carbon dioxide in a more compact gas field gas analyzer.
Extend the service life of carbon filter
Used to measure the humidity, compact and low cost maintenance of methane and carbon dioxide is a typical application of probe in organic waste anaerobic digestion (AD) domain, followed by the use of internal combustion engine to realize combined heat and power (CHP).After master water content of methane in processing phase, the operator can prolong the service life of activated carbon filter.These filters in a given range of relative humidity has a good performance, and replacement costs are relatively high.
Improve the quality of the gas and prevent engine wear
By monitoring into the CHP engine gas composition, can further improve efficiency.After mastering the methane content of gas, the operator can carry on the more accurate adjustment of engine, at the same time can detect air intake mouth water vapor levels rising, so they can rapid response could lead to premature engine wear and tear gas quality problems.Unexpected condensing a consequence is to increase the resistance to flow in the pipeline.In addition, if the valve of the water vapor began to gather, the control of engine fuel gas and air supply valve operations will be adversely affected.
MGP261 - is suitable for the harsh conditions of gas sensor
Visa pull MGP261 humidity of the gas sensor is a new, more methane and carbon dioxide detector, which is based on reliable NDIR measuring principle, the built-in in visa, the instrument used to measure carbon dioxide has 20 years of history, is reliable and accurate.
Compact (diameter of 40 mm, inserted depth of 209 mm, 1 1/2 level inches "NPT technology joint") and approved by the ATEX and IECEx can be used to 0 and 1 area, the all steel probe can tolerate condensation environment after heating, and the waterproof particulate filter protection;MGP261 measure 0...25 volume percentage range of water vapor and 0...The dew point temperature of 60 ° C scope.
Under the condition of nearly condensation, MGP261 unaffected, so to adapt to the harsh conditions.
