Model 1210 Process Control PC Board Mountable Pressure Sensor Medical Instrumentation 0-100 mV Output HVAC Gage, Differential and Absolute Barometric Pressure Temperature Compensated Air Flow Management Avionics DESCRIPTION The Model 1210 is a temperature compensated, piezoresistive silicon pressure sensor packaged in a dual-in-line configuration. It is intended for cost sensitive applications where excellent performance and long-term stability are required. Integral temperature compensation is provided over a range of 0-50C using laser-trimmed resistors. An additional lasertrimmed resistor is included to normalize pressure sensitivity variations by programming the gain of an external differential amplifier. This provides sensitivity interchangeability of 1%. Gage, absolute, and differential pressure ranges from 0-2 PSI to 0-100 PSI are available. Multiple lead and tube configurations are also available for customizing the package for specific applications. Please refer to the low pressure section for information on FEATURES products with operating pressures less than 0-2 PSI. For a Dual-in-line Package compensated sensor using a current set resistor as opposed to a 0.1% Non-linearity gain set resistor, please refer to the Model 1220. 0.5% Temperature Performance DIMENSIONS 1.0% Interchangeable Span (provided by gain set resistor) Solid State Reliability Low Power STANDARD RANGES Range psia 0 to 2 1-14 psid psig 0 to 5 0 to 15 0 to 30 0 to 50 0 to 100 HITs - Standard Model 1210 PC Board Mountable Pressure Sensor PERFORMANCE SPECIFICATIONS Supply Current: 1.5mA Ambient Temperature: 25C (Unless otherwise specified) PARAMETERS Full Scale Output Span MIN TYP MAX UNITS NOTES 75 100 150 mV 1 2 mV 2 3 Zero Pressure Output Pressure Non-linearity 0.05 0.1 % Span Pressure Hysteresis 0.01 0.1 % Span 4400 6000 Temperature Error - Span 0.3 0.5 % Span 2, 4 Temperature Error - Zero 0.1 0.5 % Span 1, 2, 4 Input & Output Resistance 2500 Thermal Hysteresis - Zero 0.1 Supply Current 1.5 mA 5 Response Time 1.0 msec 6 1.0 V p-p 7 2 M 8 50 M Output Noise Output Load Resistance Insulation Resistance (50 VDC) % Span 2.0 Pressure Overload 3X Rated Operating Temperature -40C to +125C Storage Temperature -50C to +150C Media Non-corrosive Gases Compatible with Wetted Materials Weight 3 Grams Notes 1.
