Model 1210 Low Pressure PC Board Mountable Pressure Sensor þ Medical Instruments 0-10" H2O to 0-1 PSI þ Air Flow Measurement þ HVAC þ Process Control þ Factory Automation þ Leak Detection 0-100 mV Output Gage and Differential Low Cost DESCRIPTION The Model 1210 is a temperature compensated, piezoresistive silicon pressure sensor packaged in a dual-in-line configuration and intended for cost sensitive applications where excellent performance and long-term stability are required. Integral temperature compensation is provided over a range of 0-50°C using laser-trimmed resistors. An additional lasertrimmed resistor is included to adjust the gain of an external differential amplifier. This provides sensitivity interchangeability of ±1%. The sensing element used in the low pressure Model 1210 includes a double bossed design that produces a sensor output of 100 mV (typical) at 1 PSI. The 1210 is also available in ranges up to 0-100 PSI. For a compensated sensor using a current set resistor instead of a gain FEATURES set resistor, please refer to the Model 1220. þ Dual-in-line and TO-8 Packages þ ±0.1% Non-linearity þ 1.0% Temperature Performance (typical) þ 1.0% Interchangeable Span (provided by gain set resistor) þ Temperature Compensated þ Solid State Reliability þ Low Power DIMENSIONS STANDARD RANGES Range psi 0 to 1 ● 0 to 10 1-10 in H2O ● HITs – Low Pressure Model 1210 Low Pressure PC Board Mountable Pressure Sensor PERFORMANCE SPECIFICATIONS Supply Current: 1.5mA Ambient Temperature: 25°C (Unless otherwise specified) PRESSURE RANGE 0 - 10 in H2O (Note 10) 0 - 1 psi PARAMETERS Full Scale Output Span MIN TYP MAX MIN TYP 75 100 150 25 35 Zero Pressure Output 2 Pressure Non-linearity Pressure Hysteresis MAX 2 UNITS NOTES mV 1 ±mV 2 3 0.1 0.25 0.05 0.1 ±% Span 0.01 0.05 0.01 0.1 ±% Span 4400 6000 4400 6000 Ω Temperature Error - Span 0.5 1.0 0.5 1.0 ±% Span 4 Temperature Error - Zero 0.5 1.0 1.0 3.0 ±% Span 4 ±% Span 4 2.0 1.5 Input & Output Resistance 2500 2500 Thermal Hysteresis - Zero 0.1 Supply Current 1.5 Response Time (10% TO 90%) 1.0 1.0 mS 5 Output Noise 1.0 1.0 µV p-p 6 Output Load Resistance 2 Insulation Resistance (50 VDC) 2.0 2 50 Long Term Stability MΩ 0.5 20 mA MΩ 50 0.2 Pressure Overload Operating Temperature 0.2 ±% Span/yr 20 psi -40°C to +125°C Storage Temperature -50°C to +150°C Media Non-corrosive Gases Compatible with Wetted Materials Weight 3 Grams 9 Notes 1.
