The gauge pressure / absolute pressure remote flange is Measuring range standards. The matching flange should be equipped with soft gaskets and fixed bolts and nuts (users can choose mounting bolts and nuts) For gauge / absolute pressure remote transmitters with body, the maximum height drop between the remote seal pressure is lower than 100kPa absolute pressure, the transmitter body must be lower than the remote transmission sealing device. The minimum bend radius of the capillary of 75mm, is strictly prohibited winding! Ambient temperature Low Mode (min): 3.7 mA High Mode (max): 21 mA No Mode (hold): Keep the effective value before the fault The standard setting of failure alarm is High Mode Response Time The amplifier damping constant is 0.1 sec; The sensor and flange’s damping constant is 0.2~3 sec, it depends on the range and range compression ratio. Amplifier damping time constant is adjustable from 0.1 to 60 sec by software and added to response time.

The electronic housing can be M20X1.5 cable sealing buckle, the terminal is suitable for 0.5 ~ 2.5mm2 wire The remote flange conforms to ANSI standard or DIN standard. Can be installed directly, participate in the dimension drawing Preferably in such a position that the process flange axes Electrical connection Process connection NEPSI Explosion-proof license：Ex dIICT6 NEPSI Intrinsically Safe License：Ex iaIICT4 are vertical. Deviations from this can cause a shift in the The flange’s working pressure Explosion-proof performance The transmitter can be directly flanged in any position.

Level flange rated pressure 316L stainless steel、Hastelloy C、Tantalum Process flange Transmitter body pressure limit Working condition See the table "Filling fluid, working temperature and minimum working static pressure relation table" on the next page FD3051S LA / LG absolute / gauge pressure remote transmitter is structurally composed of FD3051STG / TA series pressure / absolute pressure transmitter and welded mounted remote flange with capillary tube. The pressure acting on the side of the remote flange first passes through the diaphragm and filling liquid on the remote flange, then through the capillary tube, and finally reaches the measuring end of the measuring sensor. FD3051S LG /LA gauge / absolute pressure remote transmitter is used to measure the level, density, pressure of liquid, gas or steam, and then convert it into 4 ～ 20mADC HART current signal output. FD3051SLG / A can also communicate with FDT375 handheld terminal or FDM100Modem, and use them for parameter setting, process monitoring, etc. Function and Specifi cation Product Description Technical Parameters Table Temperature limits Min：depends on the fill fluid Max：85℃ -20 ～ 65℃ ,with LCD-indicator -40℃~70℃（OLED display ） Storage temperature/transport temperature Min：depends on the fill fluid Max：85℃ Humidity 0 ～ 100% Shock resistant Acceleration：50g Vibration resistance Note：（1）Performance level A description: The technical specifications within the limits of normal performance. （2）Performance level B description: Temporary reduction or loss of functionality or performance, it can restore itself.
