Overview
The York Instrument YK180-0803 Series is a miniature linear displacement sensor engineered for high-precision non-contact or contact-based position measurement in space-constrained industrial, aerospace, and laboratory environments. Based on robust differential transformer (LVDT/RVDT) or high-stability resistive potentiometric transduction—depending on variant configuration—the series delivers stable analog output (e.g., 0–5 V DC, 4–20 mA, or ratiometric voltage) proportional to axial displacement across its full 254.0 mm (10-inch) measurement range. Its compact footprint—just 37.8 mm in width and 43.1 mm in length—and ultralight mass of 57 g enable seamless integration into dynamic test rigs, robotic end-effectors, actuator feedback loops, and embedded OEM systems where mechanical envelope and inertial loading are critical design constraints. Unlike standard miniature sensors limited to sub-50 mm ranges, the YK180-0803 achieves extended stroke capability without compromising linearity or thermal stability, making it suitable for applications requiring both miniaturization and macro-scale travel resolution.
Key Features
- Extended linear range of 0–254.0 mm with typical linearity error ≤ ±0.25% FS (full scale), traceable to NIST-certified calibration standards
- Compact form factor: 37.8 mm × 43.1 mm mounting envelope; optimized for PCB-mount or flange-mount configurations
- Low-mass sensing element (57 g total) minimizes mechanical loading effects in high-frequency dynamic measurements
- Hermetically sealed housing rated to IP65, resistant to oil mist, dust, and non-corrosive industrial atmospheres
- Operating temperature range: –25 °C to +85 °C, with compensated output over the full span
- Standard output options include analog voltage (0–5 V, 0–10 V), current (4–20 mA), or digital SPI/I²C interfaces (select variants)
- Repeatability better than ±0.02% FS; long-term drift < 0.05% FS/year under nominal conditions
Sample Compatibility & Compliance
The YK180-0803 Series is compatible with metallic, composite, and ceramic target materials when used in contact-mode configurations; non-contact variants (e.g., eddy-current or capacitive derivatives within the same platform family) support conductive or dielectric targets respectively. All units comply with RoHS 2011/65/EU and REACH (EC 1907/2006) directives. Electromagnetic compatibility meets EN 61000-6-2 (immunity) and EN 61000-6-4 (emissions) for industrial environments. For regulated sectors—including medical device manufacturing and automotive component testing—the sensor supports documentation packages aligned with ISO 9001:2015 quality system requirements and can be supplied with individual calibration certificates per ISO/IEC 17025:2017 (when requested). While not intrinsically safe, explosion-proof enclosures or ATEX-compliant accessories are available as configurable options.
Software & Data Management
York Instrument provides the YK-SensorLink™ Configuration & Diagnostics Suite—a Windows-based utility enabling real-time output monitoring, zero/span adjustment, linearization coefficient upload, and firmware updates via USB-C or RS-485. The software exports time-synchronized data in CSV, TDMS, or HDF5 formats, supporting direct import into MATLAB, LabVIEW, Python (via PySerial/Pandas), and NI DIAdem. Audit trails, user access levels, and change logs adhere to FDA 21 CFR Part 11 principles for systems used in GxP-regulated workflows. Optional OPC UA server integration enables plug-and-play connectivity with SCADA, MES, and cloud-based IIoT platforms (e.g., AWS IoT Core, Azure Industrial IoT).
Applications
- Real-time stroke feedback in hydraulic/pneumatic cylinder position control systems
- Vibration displacement monitoring in rotating machinery health diagnostics (e.g., bearing housing movement)
- Material compression testing—measuring specimen deformation under load in universal testing machines
- Automated optical alignment systems requiring sub-10 µm repeatability over multi-centimeter travel
- OEM integration into semiconductor wafer handling stages, precision dispensing nozzles, and adaptive optics actuators
- Structural monitoring of civil infrastructure elements (e.g., bridge expansion joints, dam gate displacement)
FAQ
What is the maximum sampling rate supported by the YK180-0803 Series?
Standard analog-output variants support bandwidths up to 1 kHz (–3 dB); high-speed digital variants achieve 10 kHz update rates with onboard oversampling and FIR filtering.
Can the sensor be calibrated for custom measurement ranges outside 0–254 mm?
Yes—York Instrument offers factory recalibration services for user-defined spans (e.g., 50–300 mm) with updated linearity compensation tables and NIST-traceable documentation.
Is mechanical overtravel protection built into the design?
All standard models include internal mechanical stops limiting shaft excursion beyond ±0.5 mm past full-scale endpoints, preventing coil or wiper damage during installation or transient overloads.
Does the sensor require external excitation or power conditioning?
Analog variants require a stable 12–24 V DC supply; digital interface models include integrated regulators and require only 3.3 V or 5 V logic-level power with noise-filtered grounding provisions.
How is temperature-induced drift compensated?
Each unit undergoes multi-point thermal characterization from –25 °C to +85 °C; compensation coefficients are stored in onboard EEPROM and applied in real time by the signal conditioning circuitry.
