The NCLD-TS200 is a non-contact linear displacement sensor built for storage tank monitoring. It measures floating roof position, liquid level movement, and tank shell displacement without touching the moving target, so wear and maintenance are reduced. The sensing element uses a magnetostrictive waveguide and a magnetic float; the electronics convert position into a stable linear signal. Model: NCLD-TS200. Key specifications: measuring range 0–2000 mm; resolution 0.05 mm; linearity ±0.1% FS; repeatability ±0.05% FS; output 4–20 mA, 0–10 V, or RS485 Modbus; supply 24 VDC ±10%; protection IP67; operating temperature -40°C to +85°C; process connection G1/2 or DN50 flange; wetted material 304/316L stainless steel; target magnetic float. Cable length can reach 100 m; temperature drift is ±0.02% FS/°C, and repeatability is tested at 25°C. Optional Ex ia IIC T4 approval supports hazardous areas. A local LCD option and HART protocol are available for commissioning. Install the probe vertically on the tank top, guide the float with the liquid, and keep the target away from inlet turbulence. Connect the shield to ground, use twisted-pair cable, and set zero/span in the PLC or DCS. For model selection, confirm range, medium, temperature, output, flange, and certification. Routine inspection of cable, float, and zero point maintains accuracy. The sensor suits oil, water, and chemical storage tanks requiring reliable, low-maintenance level and displacement feedback.
