Humidity limits (non-condensing)
0 to 50°C
-25 to +85°C

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.
