Yokogawa FU20-VP-T1-NPTFPS | FU20 All-in-One pH/ORP Sensor, VarioPin, 3/4" NPT, Pt1000, PPS Body
Yokogawa FU20-VP-T1-NPTFPS combination pH & ORP sensor with integral Pt1000, PPS (Ryton) body, 3/4" NPT tapered thread, VarioPin (VP) detachable connector. Gel-filled double-junction reference, dome pH glass. Compatible with FLXA21, PH400, SENCOM.

Product Overview

The Yokogawa FU20-VP-T1-NPTFPS​ is an all-in-one wide-body pH/ORP combination sensor​ from the FU20 series, designed for inline or immersion installation in wastewater and industrial process applications. It integrates four elements—pH glass electrode, Ag/AgCl double-junction reference, solid platinum ORP electrode, and Pt1000 RTD—in a single rugged PPS 40GF (Ryton®) body​ with 3/4" NPT male tapered thread​ for direct mounting. The -VP suffix​ indicates a VarioPin detachable multi-pin connector​ (no fixed cable; requires separate VP cable such as WU10 series), and -FPS​ denotes inclusion of the F*40 adapter (PPO). Enables simultaneous pH (0–14) and ORP (±1500 mV) measurement with temperature compensation, suitable for Yokogawa FLXA21, PH400 series, and SENCOM transmitters.

Key Features

  • Four-in-One Design:​ Single sensor body measures pH + ORP + Temperature + Reference—eliminates need for separate probes.
  • Double-Junction Gel Reference:​ Large-volume polymerized KCl with PTFE porous junction resists poisoning in dirty/wastewater—extends service life vs. single-junction designs.
  • VarioPin Detachable Connector (-VP):​ Allows sensor replacement without rewiring the transmitter; pin-coded to prevent misconnection.
  • Direct NPT Mount:​ 3/4" NPT thread screws straight into a tee, pipe, or immersion fitting—no special holder required.
  • Pt1000 Built-In:​ Provides accurate temperature compensation for pH and direct temp readout to the analyzer.

Typical Applications

  • Municipal / Industrial Wastewater:​ pH & redox monitoring in aeration basins, neutralization tanks, and effluent lines.
  • Chemical Process Lines:​ Simultaneous pH and ORP (e.g., chlorine control, cyanide destruction).
  • Food & Beverage / Pharmaceutical:​ CIP rinse verification (pH swing) and sanitization cycle ORP monitoring (verify chemical compatibility).
  • Cooling Tower / Boiler Blowdown:​ pH control loops with ORP trend monitoring.
