Steam headers, vulcanizing presses, extruders and drying lines share a measurement problem: the fluid is hot enough to cook conventional transmitters, yet the pressure still has to be read. The Hefei Brans BST106 is aimed at exactly that duty - a high-temperature pressure sensor rated for media from -30 degrees C up to 800 degrees C depending on configuration, with ASIC compensation correcting the electronics rather than assuming a cool installation.

Why does no oil fill matter at temperature?

Because oil boils, degrades and migrates. The BST106 uses a fully welded stainless steel housing with no fill fluid, no internal O-rings and no exposed welds in the sensing path, so thermal cycling does not create leaks or zero drift through an elastomer. The ceramic strain gauge element with high-temperature material handles media to 160 or 220 degrees C in the standard builds and 800 degrees C in the high-temperature versions, retaining 0.25 percent FS accuracy and 150 percent safe overload.

Where does sub-millisecond response pay?

On anything that measures dynamics: hydraulic test stands, compressor controls, railway braking systems and injection processes, where a response time under one millisecond captures pressure spikes that averaged readings erase. IP65 connector versions or IP68 direct-cable versions cover wet and washdown mounting, the M20 x 1.5 or M14 x 1.5 threads screw into standard ports, and 9 to 36 VDC supply with two-wire 4-20 mA or three-wire voltage output connects to any plant I/O.
