Remote Seal Capillary Pressure Transmitter prevents pipeline medium from entering the transmitter, connecting via a fluid-filled capillary. Capillary pressure transmitter measures liquid, gas, or steam levels, flow, and pressure, converting to a 4-20 mA DC output. For closed tanks, choosing WE3051RD that ensure the high-pressure diaphragm area is fully wet for accuracy, with the center diaphragm as the zero point. For open tanks, selecting WE3051LT , also needing the high-pressure diaphragm area fully wet for accuracy, with the center diaphragm as the zero point.

What are the suitable applications for a remote seal capillary pressure transmitter ? It can be installed on a pipe or container to measure pressure, which is transmitted through silicone oil in the capillary tube. The transmitter’s main body converts the pressure into a 4-20mA signal output compatible with HART protocol. Suitable applications include:
1. High-temperature viscous media;
2. Crystallizing media;
3. Media with solid particles or suspended matter;
4. Strongly corrosive or highly toxic media;
5. Preventing pressure pipe leakage and environmental pollution;
6. Avoiding mixing of different media for accurate process measurement;
7. High hygiene and cleanliness site conditions;
8. Food, beverage, and pharmaceutical industries needing hygienic standards and easy cleaning to avoid cross-contamination.
