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.
SPECIFICATIONS
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.
