Product details
1, application
The membrane box of the differential pressure remote transmitter is used to prevent the medium in the pipeline from directly entering the pressure sensor assembly of the differential pressure transmitter. The filling liquid such as silicone oil is used to transfer the pressure between it and the transmitter.
Fl101 differential pressure remote transmitter is used to measure the liquid level, density, pressure and flow m of M liquid, gas or steam, and then convert it into 4 ~ 20mADC Hart current signal output. Fl101 can also communicate with rst375 handheld terminal or rsmioomodem for parameter setting, process monitoring, etc. Fl101 series differential pressure transmission
The M range of the device {when not moved) is 0-1kpa ~ 2MPa, and the rated pressure of the remote flange is 1.6/4mpa, 6.4Mpa, 10MPa, 150psi, 300PSI or 600psi, respectively
2. Working principle and structure
Fl101 differential pressure remote transmitter is composed of fl101 series differential pressure transmitter and welded remote flange with capillary. Its working principle is the same as that of fl101 series differential pressure transmitter (refer to the technical specifications of fl101 series differential pressure transmitter), but the pressure transmission path is slightly different: the pressure acting on the remote flange is first passed through the diaphragm and filling liquid on the remote flange, then through the capillary, finally to the corresponding positive and negative sides of the measurement sensor.

5. Response time
The damping of amplifier components is usually 0.1s; the time constant of sensor and remote flange is 0.2s-6s, which depends on the m-pass, m-pass ratio of sensor, the length of capillary, and the viscosity of filling liquid.
6. General conditions
6.1 installation conditions
The transmitter body can be directly fixed to any position s. The best condition is to make the flange axis in the vertical state, and the deviation of bit a will produce the zero position deviation which can be corrected. The electronic watch can rotate 360 ° at most, and the positioning pin can fix it in any position.
The remote flange is connected with the matching flange conforming to ANSI / DIN standard. The matching flange shall be equipped with soft gasket and fixed butterfly bolt and nut (the user can choose to install the bolts and nuts). For double flange remote transmitters, capillary components and remote flanges should only be possible to be installed at the same ambient temperature. The minimum bending radius of the capillary is 75mm. It is forbidden to wrap it!

Table 3 Relationship among filling liquid, working temperature and minimum working static pressure
Note: in case of exceeding the above range of working temperature and static pressure, it shall be specially pointed out that the requirements can be met through special design.
Pressure limit of transmitter body: from 3.5kpa absolute pressure to rated pressure, the protection pressure can be greater than 1.5 parts of rated pressure, and it is added to two cases of transmitter.

DIN standard: PN1.6MPa ~ pn10mpa
One way overload limit: the low-pressure side is the rated pressure of the transmitter body, and the high-pressure side is the rated pressure of the liquid level flange, which may cause
Zero drift that can now be corrected.
