FEATURES: |
The only materials used in these elements are ceramic and platinum, with the result that they are highly stable physically and chemically when subject to temperature changes. A fully automated production process guarantees consistant product quality at comparatively low cost. |
The elements are made exclusively of ceramic and platinum, giving excellent stability at high temperatures. They are suitedable for use between -40°C and 400°C. |
The platinum resistance film is sputtered on the ceramic surface giving outstanding resistance to vibration and shock. |
Laser trimming enables us to offer a 1000 element in addition to 100 . |
After trimming, the surface is coated with ceramic, so the elements can withstand high voltage and have high insulation resistance. |
Stability: |
After continously heating model TFP1 at 400°C for 6,000 hours the margin of error at 0°C is within 0.055°C. |
Self-Heating: |
The current used with the element should not exceed 2mA. When model TFP1 is put in a 4mm protecting tube, it's resistance value is 0.02 at 2mA when measured in agitated water at 0°C but the resistance value rises to 0.2 at 5mA. |
