Hamilton Conductivity Sensors

Hamilton’s process conductivity range covers the wide-range, 4-pole Conducell 4UxF family and the Conducell UPW family for ultra-pure water. The 4UxF measures from 1 µS/cm up to 500 mS/cm on the analog version (300 mS/cm on Arc) with FDA-compliant wetted parts and CIP, SIP and autoclave compatibility. The UPW measures 0.01 to 1500 µS/cm on the Arc version and complies with USP 645, EP, JP and FDA. As one of Hamilton’s distributors in Turkey, Mikron Proses (Üsküdar, Istanbul) supplies Conducell sensors and provides application consulting on sensor selection.

Conducell 4UxF: 4-pole, wide-range measurement

The Conducell 4UxF covers trace to very high conductivity on one platform. All wetted parts (DIN 1.4435, PEEK, EPDM) are FDA compliant and withstand CIP, SIP and autoclaving. The model code letter selects the electrode material: stainless steel 1.4435 (4USF), Hastelloy C 2.4602, titanium or platinum.

The cell constant depends on the model. The Conducell 4US-T150 family has a cell constant of 0.147/cm, works from -20 to 135 °C up to 6 bar g, and is CIP and SIP compatible with FDA-compliant wetted parts. The Conducell 4USF-VV has a cell constant of 0.36/cm, withstands up to 20 bar g at 135 °C and is autoclavable, CIP and SIP compatible, with VP output.

Conducell UPW: ultra-pure water and USP 645

The Conducell UPW is a 2-pole sensor for ultra-pure water, pure water and water for injection. The Arc version measures 0.01 to 1500 µS/cm, up to 130 °C with the digital interface and up to 10 bar g at 130 °C; it is autoclavable and compatible with CIP and SIP. It complies with USP 645, EP, JP and FDA, and the Traditional model is ATEX and IECEx approved. Process connections are PG 13.5 or a 1.5-inch Tri-Clamp, with VP or Arc output. On the Arc version, the Arc module is calibrated with a traceable UPW Simulator (REF 243580) to verify USP 645 compliance in the field.

Cell constant and model selection

Alongside the 4-pole family, the catalog includes the simpler 2-pole Conducell 2DC-PG, with a cell constant of 1/cm, a range of 10 µS/cm to 20 mS/cm, -5 to 80 °C and up to 6 bar g. The right model depends on the conductivity range (from trace UPW to concentrated CIP solutions), the process temperature and pressure and the process connection (PG 13.5, Tri-Clamp).

Which Conducell family and cell constant fit your process depends on the measuring range, the temperature and pressure and regulatory requirements such as ATEX and USP 645. Tell us about your application and we will define the right sensor together.
