Product details
Fl102-a high precision differential pressure transmitter
Fl103-a high precision differential pressure transmitter
Fl102 / 3-A high dry degree differential pressure / absolute pressure transmitter is used to measure the liquid level, density and pressure of liquid, gas or steam, and then convert it into 4 ~ 20mADC Hart current signal output. Fl102 / 3-A can also communicate with rst375 handheld terminal or rsmioomodem for parameter setting, process monitoring, etc.
Standard specification: (adjust * range based on standard zero point, stainless steel 316L diaphragm, filling liquid is silicone oil)

2. Functional specifications
Limit of path
Within the upper and lower limits of m-pass, it can be adjusted arbitrarily. It is recommended to select m program code with the lowest m program ratio as possible to optimize performance characteristics.
Setting range and range (fi102-a high precision gauge pressure >
Range and range (fl103-a high precision absolute pressure)
Zero point setting: zero point and M range can be adjusted to any value within the range of M measured in the table, as long as the calibration is the minimum range
Influence of installation position: the change of installation position s parallel to and reverse to the one-sided will not cause zero drift effect. If the change of installation position s and membrane one-sided exceeds 90 °, there is a zero effect within the range of < 0.25kpa in m-pass C, and < 0.15kpa in other m-passes
The influence of internal zero position can be corrected by adjusting the extraction. There is no impact of M process.
Output: 2-wire system, 4-20madc Hart output, digital communication, linear or square root output can be selected, HART protocol is added to 4-20madc signal.
Output signal limit: 1min = 3.9ma, Lmax = 20.5ma
Bitter current: low alarm mode (minimum): 3.7 Ma
