BXY6002 gauge pressure remote transmitter

BXY6003 Absolute Pressure Remote Transmission Transmitter

1 Application
The diaphragm box of the remote transmitter is used to prevent the medium in the pipeline from directly entering the pressure sensor component of the transmitter. It uses silicone oil and other filling liquids to transmit pressure between the transmitter and it.
The BXY6002/3 gauge/absolute pressure remote transmitter is used to measure the liquid level, density, and pressure of liquids, gases, or vapors, and then convert them into 4- 20mADC HART current signals for output. BXY6002/3 can also communicate with RST375 handheld terminals or RSM100 Modems for parameter setting, process monitoring, etc. The measurement range of the BXY6002/3 gauge/absolute pressure remote transmitter (when not relocated) is 0- 6kPa~25MPa, 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
The BXY6002/3 gauge/absolute pressure remote transmitter consists of a BXY6002/3 series gauge/absolute pressure transmitter and a welded and installed capillary remote flange. Its working principle is the same as the BXY6002/3 series gauge/absolute pressure transmitter (refer to the technical specifications of the BXY6002/3 series gauge/absolute pressure transmitter), but the pressure transmission path is slightly different: the pressure acting on the remote flange side first passes through the diaphragm and filling liquid on the remote flange, then through the capillary, and finally reaches the measurement end of the measurement sensor.

5 Response time
The damping constant of the amplifier component is 0.1s; The time constant of the sensor and remote flange is 0.2-6s, depending on the sensor's range, range ratio, capillary length, and the viscosity of the filled liquid. The additional adjustable time constant is 0.1~60s.
6 General conditions
6.1 Installation conditions
Gauge/absolute pressure remote transmitters without capillaries can be installed directly through remote flanges, and positional deviations will result in correctable zero offset. The electronic watch case can rotate up to 360 °, and the positioning screw can fix it in any position.
The gauge/absolute pressure remote transmission flange is connected to a matching flange that complies with ANSI/DIN standards. The matching flange should be equipped with soft gaskets and fixed bolts and nuts (users can choose to install bolts and nuts).
For gauge/absolute pressure remote transmitters with capillary tubes, if the remote sealing device is lower than the transmitter body, the maximum height difference between the remote sealing device and the transmitter body should be<5m. When the working pressure is below 100kPa absolute pressure, the transmitter body must be lower than the remote sealing device.
The minimum bending radius of the capillary is 75mm, and winding is strictly prohibited!
