Endress+Hauser CUE22-A1A | pH/Conductivity Sensor Immersion Fitting, PVDF, G1"


Endress+Hauser CUE22-A1A | pH/Conductivity Sensor Immersion Fitting, PVDF, G1"
Endress+Hauser CUE22-A1A immersion/flow-through fitting for pH, ORP & conductivity sensors. PVDF body, G1" process connection, Pg13.5 sensor port, max 6 bar, IP67.

Product Overview

The Endress+Hauser CUE22-A1A​ is a standard immersion and flow-through fitting​ designed for mounting pH, ORP, conductivity, and oxygen sensors​ (with Pg 13.5 process threads such as CPS11D, CPF81D, CLS21, COS41) into open tanks, basins, or pipe tees. It features a PVDF (polyvinylidene fluoride) body​ for excellent chemical resistance, a G1" female process connection, and a Pg 13.5 (≈27 mm) sensor port​ with compression seal. This version is configured for immersion mounting​ or installation in a flow cell (by-pass)​ and is widely used in water treatment, chemical dosing, and wastewater monitoring.

Key Features

  • Universal Sensor Fit:​ Accepts any Endress+Hauser sensor with Pg 13.5 thread​ (pH, ORP, conductivity, DO), making it a versatile platform across multiple measurement types.
  • Chemical Resistance:PVDF construction​ withstands aggressive media including chlorine, acids, and oxidizing agents — far superior to standard PVC or PP in many process waters.
  • Flexible Installation:​ Can be immersed directly into tanks via a mounting flange or installed in a by-pass flow cell​ for representative sampling from a pressurized line.
  • Secure Compression Seal:​ Integrated Pg 13.5 compression nut and seal ring ensure leak-tight sensor retention under rated pressure/temperature.

Applications

  • Wastewater Neutralization Basins:​ Immersion mounting of pH electrodes (CPS11D) for continuous pH monitoring.
  • Chemical Dosing Skids:​ In-line flow-through installation for conductivity (CLS21) or ORP (CPS12D) verification.
  • Cooling Tower / Boiler Blowdown:​ Sampling loop mounting for water quality sensors.
  • Potable Water Disinfection:​ Mounting of free chlorine (CCS50D) or ozone sensors in sample streams.

Note: For retractable / retractable-with-ball-valve versions, see CUE23 / CUE24 series. For hygienic (3-A / EHEDG) tri-clamp fittings, see CUE25 / CUE26 series.
