5.Ordering Information
1.In order to ensure that the sensor can safe and reliable operate, you can installed three valves between the sensor and the measured point to ensure that the medium slow and evenly applied to the positive, negative pressure in the cavity of the  differential pressure sensor.
2.Suggest that level of small range differential pressure sensor installation. 
3.Pay attention to the  pressure range and the static pressure value of the differential sensor can meets the corresponding requirements of the measured differential pressure point.
4.It is strictly prohibited to negative pressure higher than positive pressure in the cavity.
