Brief Introduction

When the dp level transmitter and the device under test are connected with a capillary, it becomes a differential pressure transmitter with remote transmission. The filling silicone oil (or other liquid) is transferred to the main body of the transmitter, and then the pressure or differential pressure is converted into 4-20mA.DC signal output by the delta chamber and the amplifying circuit board in the main body of the transmitter, which is consistent with HART It can communicate with each other for setting and monitoring with the cooperation of the hand-held communicator of the protocol.
