Ee893 digital co2 sensor module for oem applications The e+e co2 module ee893 is designed for oem applications and for demanding environment. A multiple point co2 and temperature adjustment procedure leads to excellent co2 measurement accuracy over the entire temperature working range; this is a must for process control and outdoor applications. The e+e dual wavelength ndir co2 sensing procedure compensates automatically for ageing effects. Ee893 is highly insensitive to pollution and offers outstanding long term stability. With its small dimensions and electrical connection via contact pins and pads, ee893 is the optimal choice for oem devices such as wireless transmitters, hand-helds or data loggers. The measured data, with a range of up to 10000ppm, is available on the e2 digital interface. An optional kit facilitates easy configuration and adjustment of the module. The measurement interval can be set according to the application requirements; by this the average current consumption can be reduced to less than 60î¼a for battery-operated devices.

Heat Treatment DIN 1.2379 steels alloy should be preheated very slowly to 815 (1500 F) and the temperature can be increased to 1010oC (1850 F). Then held at 1010oC (1850 F) for 20 to 45 minutes and air-cooled (air quenched). Annealing Annealing of 1.2379 tool steels material should be done at 871 to 898 C (1600 to 1650 F) followed by slow furnace cooling at 4.4 C (40 F) per hour or less, after which cooling rate could be increased. At the same time, must do something to prevent excessive carburization or decarburization. Stress Relieving Heat it slowly to 1050 -1250 F, allow to equalize, and then cool in still air(Strain Relieving) Preheat Prior To Hardening Preheat slowly to 1350 -1450 F and hold at this temperature until steel 1.2379 steel material is uniformly heated. Hardening After thorough preheating, heat to 1800 -1850 F. Hold it at the hardening temperature until it is completely and uniformly heated. Quenching DIN 1.2379 steel tool material is an air hardening steel and will develop hardness on cooling in still air. To avoid scaling and prevent decarburization on the surface, controlled atmosphere or vacuum furnaces are recommended. Parts should be allowed to cool to 150F, or to where they can be held in the bare hand, and then temper immediately. Tempering The tempering temperature on material 1.2379 steel may be varied according to the desired hardness. 1.2379 steels can be tempered at 204 C (400 F) for achieving Rockwell C hardness of 61 and at 537 °C (1000 F) for a Rockwell C hardness of 54. Compare Chinese Cr12Mo1V1 steel, American D2 steel, Japanese SKD11 steel, the chemical composition of them is the same, but the performance is very different. After heat treatment, the color of Cr12Mo1V1 is a little orange-red, and the deformation would be large. It is easy to fracture during use. And the hardness of D2 steel is higher than SKD11 steel, but the toughness is not better than SKD11 steel. SKD11 steel is light and smooth, with the best overall performance. D2 Steel Forging Heating for forging of AISI D2 tool steel should be done slowly and uniformly. Soak through at 1850 -1950 F and reheat as often as necessary, stopping work when the temperature drops below 1700 F(926 C). After D2 mold steel forging, cool slowly in lime, mica, dry ashes or furnace. D2 steel should always be annealed after forging. Songshun specialized in Special Steel for almost 20 years. We can supply mold steel, high speed steel, alloy steel, free cutting steel and etc.Welcome your contact 24 hours a
