Explanation: 1) If there is an overload in the measured pressure, please provide the overload pressure value.
2) If the temperature of the measured medium continues to reach 130 ℃ or below -20 ℃, it is recommended to use a temperature isolator or capillary structure to ensure that the sensor is not damaged.
