CAUTION
Applications requiring supply voltages greater than 20 V on power-up must have a 10 Ohm resistor installed
between pin 1 of the sensor and the positiv (+) lead of the power supply.
If the sensor is subjected to a supply voltage of >20 V without ramp up, a current spike may occur causing the
operational amplifier and/or the ASIC to fail.
Do not operate above 30 V max. Due to internal component ratings, the maximum safe operating voltage
specification is 30 V.

Notes
1
Proof pressure is the maximum pressure which may be applied without causing durable shifts of the electrical parameters of the sensing element.
2
Burst pressure is the maximum pressure which may be applied without causing damage to the sensing element or leaks from the housing.

Full scale span is the algebraic difference between the output voltage at full-scale pressure and the output at zero pressure.
4
Total accuracy includes non-linearity, hysteresis, repeatability, zero offset and span error, thermal effect on zero offset and span.
Non-linearity refers to the
Best Straight Line
fit measured for offset pressure, full-scale pressure and ½ full-scale pressure.
