QS83-S2 Monocrystalline Silicon Dual-Flange Capillary Remote-Seal Level Transmitter
Dual-flange capillary remote seal, H/L sides each 0–20 m, differential-pressure level measurement for sealed tanks.
- Original Factory Genuine, Tenfold Compensation for Counterfeits
- Full Machine Warranty, Lifetime Maintenance
- In Stock, Shipped on the Same Day
QISON QS83-S2 dual-flange capillary remote-seal level transmitter; both high- and low-pressure sides use remote diaphragm-seal flanges, with capillary lengths of 0–20 m on the H/L sides. Suitable for differential-pressure level measurement of sealed tanks and of crystallising and scaling media; the pressure taps can be located away from high-temperature zones and require no impulse-line maintenance.
Four diaphragm-seal fill fluids available (up to 380 °C); flat/convex/flat-convex flanges DN25–DN100; seven diaphragm materials, three flange materials, four insertion-tube materials; diaphragm extension lengths on the H/L sides independently selectable.
