HT-SY50-EX Oxygen Analysis System Summary: Explosion-proof oxygen analysis system is made of pretreatment, sampling and analysis. The pretreatment part adopts neutralization, dilution or adsorption to remove or dilute the media which may affect the sensor in the sample gas to the allowable concentration, to ensure the service life and measurement accuracy of the analysis part.
Our products include online type and portable type, and there are explosion-suppression and intrinsic safe type of explosion-proof products. Analysis media include oxygen, hydrogen, carbon monoxide, methane and acetylene, etc. They are already widely applied in chemical industry, oil refining, building materials, metallurgy, power, environmental protection, pharmaceutical, food and national defense and other industrial fields, such as on-line monitoring of thermal power, centrifuge, reaction kettle, tank, pipeline, etc.
a. The segment code display mode is clear and intuitive, and the operation of the instrument is easy and convenient;
b. Sensors in all modules are originally imported, and they have a rapid response speed, high measurement accuracy, excellent linearity, long calibration cycle and stable performance, also the sensor can be changed when reaching its service life;
c. In explosion-proof occasions, the menu can be set by isolated-type magnetic pen, which is convenient for on-site operation;
d. The menu lock function could prevent mis-operation, which may change instrument parameters and affect its performance;
e. Automatic temperature compensation function could eliminate the impact of environmental temperature changes on the measurement accuracy;
f. The instrument allows multi-point fractional liner calibration, meeting the need for an accurate measurement of oxygen content among the full range;
g. The gas path of the measured cavity is designed specially with a polymeric membrane attached, which could effectively prevent fluid or interference media affecting the sensor.
l The system cabinet is spared with stainless-steel (Spray-painted cabinet is available) on its surface. Its front door is transparent glass window (600mm×600mm×250mm), and the cabinet wall-mounting;
l Except for the gas transmitter (Exd IIC T6), other components in the system are pretreatment components and pipe valves which can be used for explosion-proof level of Ex db IIC T6 Gb and Ex tb IIIC T80℃ Db;
l Explosion-proof solenoid valve could perform remote automatic control on the supply of gas (optional);
l Condenser removes water in the sample gas by cooling the gas (optional);
l Pneumatic sampling pump is used to sample gas in negative pressure condition (optional);
l Level-three pretreatment component is visible and transparent. The sampling pipe is made of 316L Φ6mm seamless stainless-steel pipe. Cutting ferrules and joints are corrosive-resistant cutting ferrules from Yuanheng, Taiwan;
l Gas transmitter of different ranges can be equipped according to the conditions, which are trace oxygen system and normal oxygen system;
l Corresponding sampling system can be designed according to the conditions, which are positive pressure, micro-positive pressure and micro-negative pressure sampling system.
It is widely applied in the gas concentration measurement in the environment where the explosion-proof grade is Exd IIC T6. It has been widely used in petroleum, chemical industry, metallurgy, refining, gas distribution, biochemical medicine and other industries.
