Contact Displacement Sensor
SDM Multi-Ten Thousand Digit Display Integrated Contact Displacement Sensor
The SDM multi-dimensional integrated contact displacement sensor adopts the LVDT inductive measurement principle, integrating high-precision displacement measurement, numerical display, RS485 communication, and IO tolerance output. The product has a resolution of up to 0.1 μm and a repeatability of <1 μm. It can be used for height, thickness, depth, runout, vibration, flatness, and dimensional tolerance detection, and is suitable for automated equipment, precision tooling, online inspection systems, and upgrades to traditional dial indicators and electronic probes.
Send InquiryKey Features
- • LVDT inductive contact measurement offers excellent stability. Its 0.1 μm resolution is suitable for precision measurements at the 10,000-level. Repeatability <1 μm meets high-precision dimensional measurement requirements. The integrated digital display allows for real-time display of measured values. It supports RS485 communication and comes standard with Modbus-RTU protocol. It supports IO tolerance output and can detect upper and lower tolerance limits. Optional structures include spring-loaded, side-leaded, and pneumatic types. It supports data zeroing, upper and lower tolerance settings, and correction value settings. Its compact design supports DIN rail mounting. It is comparable to similar contact displacement measurement applications from Marposs, Marlboro, Climax, and Keyence.
