Finally, for practical applications, an electronic interface circuit for the resistance temperature detector (RTD) device was used, to demonstrate the functioning of the devices for their end application in temperature sensing. The average value of temperature coefficient of resistance (TCR) was observed to be ~ 1976 ppm/☌ without annealing, which increased to ~ 2839 ppm/☌ with annealing up to 1000 ☌. Thin film platinum resistance temperature detector (RTD) prototype devices, with sensing element of width ~ 40 µm and thickness of ~ 164 nm were fabricated and their TCR values were evaluated with and without thermal annealing treatment. These thin films were then characterized with the scanning electron microscopy and X-ray photoelectron spectroscopy to optimize thickness and identify their elemental compositions. Chromium oxide thin films were prepared by using the RF magnetron sputtering technique. The stainless steel material comes with a self-adhesive protective foil, which also facilitates its processing. Foil residues are unavoidable and do not constitute a reason for a claim.This paper reports, the impact of high-temperature annealing on temperature coefficient of resistance (TCR) of platinum thin films, by using chromium oxide as an intermediate adhesion layer. We therefore recommend to always use protective gloves when handling our products. Please be aware that the edges of products made of stainless steel can be much sharper than the ones made of galvanized steel. The tightening should be carried out carefully and by hand. Common oil and grease are rarely enough and seizure still takes place. TECCEM AHT415) should be used on stainless steel nuts and bolts. A lubricating, anti-seize compound for stainless steel parts (i.e. Unless a suitable lubricant is used, the bolts and nuts are seized : we cannot further tighten and even untighten them. That creates a rough surface which, in conjunction with the chromium oxide layer, increases the friction dramatically. Stainless steels are harder and more difficult to machine. The springs, screws, bolts and the metal knobs for the high temperature versions are made of stainless steel V2A.Īssembly Instructions for Products made of Stainless Steel Maximum Operating Temp.: 300☌ (temporarily:450☌).Īpplications : Higher resistance against corrosion.Īccess Doors in Stainless Steel V2A and V4A Standard: V4A usually refers to the stainless steel 1.4404 (ASTM 316L).Īlternatives: grade1.4571 (ASTM 316Ti) or a comparable quality within the same category. V2A is not suitable for swimming pool applications, as this material does not resist to chloride concentrations above 150-200 mg/l. Maximum Operating Temp.: 300☌ (temporarily: 450☌).ĭata also depend on the gasket and the flow medium.Īpplications: Food and pharmaceutical industries, chemical equipment. Special upon request: shiny surface 2R (ex III D). V2A refers to the below mentioned quality or a comparable stainless steel within the same category. along the welds, iron impurities, mixed iron crystals). The products made of stainless steel are not passivated. The stainless steel might discolor when heated (i.e. This chromium part forms a passive film of chromium oxide, which prevents further surface corrosion and blocks corrosion from spreading into the metal‘s internal structure. Stainless steel is defined as a steel alloy with a minimum of 11,5% chromium content. ![]()
