Industrial SBT-2400 Blade Consistency Transmitter

The BTG Pulptec SBT-2400 Blade Consistency Transmitter is a fixed, inline device that measures the fiber consistency of pulp suspensions by sensing the shear force as slurry flows past a stationary blade. It comprises a blade, a measuring module, and an electronics module, and it uses a proven shear‑force measuring principle to indicate concentration changes in real time. The transmitter provides a 4–20 mA current output with HART as standard, with Profibus PA available as an option, and it supports four preset calibration curves plus multi‑point calibration for different pulp grades. Typical installations run from a 230 VAC, 50 Hz supply, and the unit is housed in an IP65 enclosure with a PN25 pressure rating, capable of ambient temperatures up to 60°C and process temperatures up to 100°C, at speeds of 0.5–5 m/s. The SBT‑2400 is designed for rugged service, offering a modular design and a factory‑supported exchange system for critical parts to simplify maintenance, while maintaining measurement accuracy across a wide range (roughly 1.5% to 16% Cs, depending on calibration). While most BTG Pulptec documentation describes a 230 VAC variant, some listings refer to a 35 V DC version of the fixed blade transmitter, reflecting available power-supply options for this model.
