 Remote Differential pressure / pressure transmitter is used to prevent the pipeline in the medium directly into the transmitter pressure sensor component, it is between the transmitter fill fluid by capillary connected. Used to measure liquid, gas or steam level, flow and pressure, and then into 4 ~ 20mA DC output. 
 JH1151/3351DP/GP differential pressure / pressure transmitter remote seal wear, resulting in an JH1151/3351DP/GP remote differential pressure / pressure transmitter, it still has JH1151/3351DP/GP differential pressure / pressure change various characteristics of the transmitter. HART-can communicate with each other through it for setting and monitoring. 
 Avoiding the measured medium and the transmitter isolation diaphragm direct contact, this measurement method is suitable for the following situations: 
 1, the measured medium on the corrosive effect of the transmitter sensor 
 2, the need to isolate the transmitter measured medium temperature 
 3, the measured medium in suspended solids or high viscosity media 
 4, the measured medium pressure pipe from the lead or lead crystal at the same time easy to cure 
 5, the replacement of the media should be strictly tested probe purification 
 6, the measuring head must be kept sanitary, non-pollution. Use object: liquid corrosive or viscous 
 Note: The vacuum should not be used where remote transmitter. 
 JH1151/3351DP/GP remote differential pressure / pressure transmitter four types of remote devices: 
 1,1191 PFW flat remote device (standard 3 ", working pressure 2.5MPa) 
 2,1191 RTW-type screw-mount remote device (maximum working pressure of 10MPa) 
 3,1191 RFW-type flange mounted remote device 
 4,1191 EFW based remote device into the drum (standard 3 "or 4", working pressure 2.5MPa)
