ZNI1000 TEMPERATURE SENSOR DESCRIPTION The ZNI1000 is a Ni thin film Resistance Temperature Detector (RTD), specified to DIN 43760. The high temperature coefficient offers higher signal outputs than other RTD’s, which results in higher accuracy with smaller temperature changes.

The temperature failure caused by the measurement current can be calculated with: T = P/EK where P = I² * R is the heat power caused by the measurement current and EK is the self heating coefficient. The self heating coefficient for the Ni1000-SOT is EW=(1,7 ± 0,3) mW/K (Air: 23°C; no air flow) Issue 4 - April 2006 3 SEMICONDUCTORS ZNI1000 Issue 4 - April 2006 SEMICONDUCTORS 4 ZNI1000 PACKAGE OUTLINE PAD LAYOUT CONTROLLING DIMENSIONS IN MILLIMETERS APPROX CONVERSIONS INCHES PACKAGE DIMENSIONS Millimeters DIM Inches Min Max Min Max A 2.67 3.05 0.105 0.120 B 1.20 1.40 0.047 C ᎏ 1.10 ᎏ D 0.37 0.53 F 0.085 0.15 G 1.90 NOM Millimeters DIM Inches Min Max Max Max H 0.33 0.51 0.013 0.020 0.055 K 0.01 0.10 0.0004 0.004 0.043 L 2.10 2.50 0.083 0.0985 0.015 0.021 M 0.45 0.64 0.018 0.025 0.0034 0.0059 N 0.95 NOM 0.0375 NOM ᎏ ᎏ ᎏ 0.075 NOM © Zetex Semiconductors plc 2005 Europe Americas Asia Pacific Corporate Headquarters Zetex GmbH Streitfeldstraße 19 D-81673 München Germany Zetex Inc 700 Veterans Memorial Hwy Hauppauge, NY 11788 USA Zetex (Asia) Ltd 3701-04 Metroplaza Tower 1 Hing Fong Road, Kwai Fong Hong Kong Zetex Semiconductors plc Zetex Technology Park Chadderton, Oldham, OL9 9LL United Kingdom Telefon: (49) 89 45 49 49 0 Fax: (49) 89 45 49 49 49 [email protected] Telephone: (1) 631 360 2222 Fax: (1) 631 360 8222 [email protected] Telephone: (852) 26100 611 Fax: (852) 24250 494 [email protected] Telephone (44) 161 622 4444 Fax: (44) 161 622 4446 [email protected] These offices are supported by agents and distributors in major countries world-wide.
