[Specificities]

1. The central sensor of the monocrystalline silicon sanitary differential pressure transmitter adopts globally advanced and imported composite multiple micro silicon solid-state sensors, which greatly improves the accuracy, stability, and anti-interference ability of the traditional metal capacitive pressure/differential pressure transmitter by up to ± 0.1% platinum level accuracy;

2. Multiple diaphragm materials are available for measurement of various corrosive and viscous media

3. Clamp type installation, easy to disassemble and clean, suitable for sanitary occasions such as medicine, food, and beverages

4. The remote differential pressure transmitter adopts advanced high-temperature patented technology and can be applied to 400C high-temperature measurement occasions

5. OLED dot matrix display, wide viewing angle, uniform image quality, and wide operating temperature (-40~+80 ℃);

6. The sensor is internally integrated with a high sensitivity temperature sensor, and the transmitter has excellent temperature performance, with an accuracy of ≤ ± 0.04%/10K;

7. All stainless steel 316L silicone oil filled and welded sealing structure;

8. Stable and reliable, with long-term drift of ± 0.1%/36 months, and maintenance free for 120 months;

9. An adjustable range ratio of 100:1.

[Working Principle]

　　The BST9900-WD nano monocrystalline silicon intelligent hygiene differential pressure transmitter is used to measure the liquid level, density, and pressure of liquids, gases, or vapors, and then convert it into a 4-20mADCHART current signal output. BST9900-WD can also communicate with HART375 or BSTModem for parameter setting, process monitoring, etc. Adjust the range with Normalnull as the benchmark, stainless steel 316L diaphragm, and silicone oil as the filling fluid.
