SCC30D

SCC SERIES Pressure Sensors FEATURES · 0 - 5 to 0 - 300 psi · Low Cost Sensor Element · Internal Temperature Compensation · Differential, Gage and Absolute GENERAL DESCRIPTION The SCC series offer an extremely low cost sensor element with a temperature stable output when driven with a constant current source. These integrated circuit sen-sors were designed for extremely cost sensitive applications where precise accuracy over a wide temperature range is not required. This series is intended for use with non-corrosive, non-ionic working fluids such as air and dry gases. Absolute devices have an internal vacuum reference and an output voltage proportional to applied pressure. The differential devices allow application of pressure to either side of the diaphragm and the devices are thereby available to measure both differential and/or gage pressures. This product is packaged either in SenSym´s standard low cost chip carrier "button" package, a plastic ported "N" package, a metal package or a dual inline package (DIP). All packages are designed for applications where the sensing element is to be integral to the OEM equipment. These packages can be O-ring sealed, epoxied, and/or clamped onto a pressure fitting. A closed bridge four-pin SIP configuration is APPLICATIONS · Pneumatic Controls · Automotive Diagnostics · Medical Equipment · Dental Equipment · Environmental Controls Scale: 1cm ½ inch provided for electrical connection to the button package. The TO can and the DIP offer a 5-pin open bridge configuration. EQUIVALENT CIRCUIT Vs ELECTRICAL CONNECTIONS GND 1 out + 2 +VS 3 out - 4 + Output SCC..

Accuracy is the sum of Hysterisis and Linearity. Hysterisis is the maximum output difference at any point within the operating pressure range for increasing and decreasing pressure. Linearity refers to the best straight line fit as measured for the offset, full-scale and 1/2 full-scale pressure at 25°C. This is the maximum temperature shift for span when measured between 0°C and 50°C relative to the 25°C reading. Typical temperature coefficients for span and resistance are -2200 ppm/°C and +2200 ppm/°C respectively. This is the maximum temperature shift for offset when measured between 0°C and 50°C relative to the 25°C reading. Span is the algebraic difference between the output voltage at full-scale pressure and the output at zero pressure. Maximum difference in output at any pressure with the operating pressure range and temperature within 0°C to 50°C after: a) 100 temperature cycles, 0°C to 50°C b) 1.0 million pressure cycles, 0 psi to full-scale span Response time for a 0 psi to full-scale span pressure step change. 10% to 90% rise time Temp effect on span and offset are guaranteed by design. Therefore these parameters are not 100% tested. The SCC100D devices can only be used in a forward gauge mode. Application of more than 30 psig to the back side of any of the SCC Series devices can result in device failure. 7: 8: 9: January 1998/040 Aubinger Weg 27, 82178 Puchheim, Germany Phone 0049 - (0) 89 80 08 30, Fax 0049 - (0) 89 8 00 83 33 http://www.sensortechnics.com SCC SERIES Pressure Sensors PHYSICAL DIMENSIONS Button Package Basic Sensor DIP "D2" Package January 1998/040 Aubinger Weg 27, 82178 Puchheim, Germany Phone 0049 - (0) 89 80 08 30, Fax 0049 - (0) 89 8 00 83 33 http://www.sensortechnics.com SCC SERIES Pressure Sensors PHYSICAL DIMENSIONS (cont.)
