Seeking help with differential pressure transmitter range issues
Thread Content
As for the differential pressure transmitter, 1. Is this maximum operating pressure the maximum pressure that the diaphragm box can withstand on one side? 2. What does the factory-set range of 0-100kpa mean? Can it be modified? What is the scope of the modification?
Modification range: -100 to 100
The maximum operating pressure refers to the condition where a pressure of 16 Mpa is applied to both the positive and negative pressure chambers, at which point the pressure difference is zero. It indicates that the table can operate properly at a pressure of 16 Mpa. This pressure is also known as the maximum static pressure.
This needs to be adjusted using a manual controller
1: The maximum operating pressure refers to the condition where a pressure of 16 Mpa is applied to both the positive and negative pressure chambers, at which point the pressure difference is zero. It indicates that the table can operate properly at a pressure of 16 Mpa. This pressure is also known as the maximum static pressure. The range is 0-100 KPa, and it can be adjusted using a Hart handheld communicator. An analog output of 4-20 mA is provided within the 0-100 range
Make changes using the HART handheld device; modifications can be done up to 100 KPa
Used at a pressure of 16 MPa, with a pressure difference range of 100 KPa
Take a look at the EJA selection samples
Range: -100 to 100 kPa, maximum static pressure on one side: 16 MPa
-How is 100-100 determined?
