Endress+Hauser CPS11D-7BT21 | Memosens pH Electrode, 0–14 pH, Refillable KCl, Pg 13.5
Endress+Hauser CPS11D-7BT21 digital pH sensor with Memosens 2.0. 0–14 pH range, refillable KCl/gel reference, PTFE diaphragm, Pg 13.5 process connection, IP68, for water & wastewater.

Product Overview

The Endress+Hauser CPS11D-7BT21​ is a digital pH glass electrode​ from the Memosens CPS11D series​ — the industry-standard sensor for continuous pH measurement in water, wastewater, and utility applications. It features Memosens 2.0 digital technology​ for contactless signal transmission and lab calibration. This variant has a refillable KCl/gel reference system​ (vs. the sealed gel version -7BA21), PTFE ring diaphragm, and a Pg 13.5 (Ø 27 mm) threaded process connection. The sensor is suitable for measuring pH in the 0–14 range​ with integrated NTC 30kΩ temperature sensor.

Key Features

  • Memosens 2.0 Digital:​ Inductive coupling eliminates moisture issues at the connector, stores calibration data/sensor ID in the sensor head — enables lab pre-calibration and plug-and-play replacement.
  • Refillable Reference:​ Unlike the sealed -7BA21, this -7BT21 allows periodic KCl refill to extend service life in applications with high contamination or prolonged deployment.
  • Anti-Poisoning Design:​ Double-chamber reference​ with KNO₃ bridge​ and PTFE ring diaphragm​ provides resistance to sulfide (S²⁻), cyanide (CN⁻), and heavy metal ion poisoning.
  • System Compatibility:​ Connects directly to Liquiline CM442 / CM42 / CM82 transmitters​ or any Memosens-compatible system.

Applications

  • Wastewater Treatment:​ pH monitoring in inlet, neutralization basins, and effluent discharge — especially where extended deployment benefits from electrolyte refresh.
  • Drinking Water:​ Post-chlorination pH verification and raw water monitoring.
  • Industrial Water:​ Cooling water, boiler feedwater, and chemical dosing control loops.
  • Chemical Process (Mild):​ Acid/alkali concentration monitoring in non-aggressive process streams.
Difference vs. CPS11D-7BA21:The -7BT21 is refillable​ (requires periodic KCl top-up), whereas -7BA21 is sealed gel​ (maintenance-free but shorter life in harsh media). Choose -7BT21 for longer campaigns or higher contamination risk; choose -7BA21 for low-maintenance standard duty.*
