| BMS compatibility | Agilent has no industrial protocol and is easy to integrate into BMS | High resolution A/D and high-precision input devices in the mass market |
Design improvement
1. Sensor protection tube with appropriate welding and pressure testing.
2. Cone shaped heat sink reduces local turbulence (vibration).
3. Test plug at 35 bar
4. Electrical wood terminal head (IP68)
Prevent terminal condensation and wire corrosion.
Fix the sensor in place to prevent "popping out" caused by internal pressure (Rd di i f b bi 25 35 ° C)
Reduce temperature gradient interference caused by ambient temperature (25-C).
5. Install the board to secure the sensor in place.
6. Quick Connection - Convenient 6. Quickly install connectors and exposed conductors.
7. A single sensor tag with a serial number for calibrating traceability.
8. Ensure minimal immersion in the pipeline for new projects.
Note: Due to the hot attack program, additional length is required for re debugging.
9. Combining vibration absorbers
10. Ensure that the exposed tip of the sensor is 10mm.
