In harsh shield tunneling environments, reliable position feedback is essential for hoist safety, synchronization, and precision. As a specialized manufacturer of high-temperature linear displacement sensors, we build rugged measurement solutions for shield tunneling hoists that withstand heat, vibration, dust, moisture, and continuous operation. Our sensors provide stable analog or digital output, high repeatability, and flexible stroke lengths for accurate lifting control and load positioning. Each unit uses heat-resistant materials, a sealed stainless-steel housing, EMI shielding, and wide temperature compensation to ensure consistent performance in tunnel boring and heavy material handling. We offer customized stroke length, mounting interface, cable routing, connector type, and signal output to match specific hoist systems. Strict calibration, aging tests, and end-of-line inspection help reduce downtime and extend service life. The sensors are suitable for wet, dusty, and high-vibration sites where standard position devices often fail. From prototype validation to batch production, our engineering team provides responsive technical support and fast delivery for tunnel contractors and equipment integrators worldwide. Choose our high-temperature linear displacement sensors for safer shield tunneling hoist operation, lower maintenance costs, and dependable measurement in extreme conditions.
