Conductivity measurements for pharmaceutical applications

Conductivity meter for pharmaceutical applications

Valmet conductivity sensors are ideal for steaming in place (SIP) control. Our conductivity sensors are extremely resistant to rapid temperature changes thanks to their unique design. There are several special sensors for water for injection (WFI)/ultra-pure water (UPW) measurements. Our extremely reliable sensors ensure there are no unscheduled production shutdowns. We guarantee that the conductivity sensors keep on measuring accurately, year after year. We have installations that have measured for five years without the need for calibration.

EHEDG certified sensors

All Valmet sensors in pharmaceutical applications fulfill EHEDG requirements for material, surface roughness, and steam cleaning. The Valmet sanitary sensors have been EHEDG Type EL Class 1 certified. All wetted surfaces fulfill the hygienic requirement of surface roughness Ra ˂ 0,8 µm. The steel parts are made from AISI316L and plastic (Teflon) fulfills EU and FDA requirements on materials used in contact with food. The sensors are available with 3.1 material certificate, calibration certificate, surface roughness certificate, and EHEDG certificate.

The conductivity sensors have a pressure rating of 12 bar at 150 °C. All Valmet conductivity products are designed to withstand fast temperature changes. The structure is very simple, and all sensitive components are located far from the measurement head. Each sensor is heat treaded during production to make sure the changing temperature has no effect on the sensor accuracy.

Portable conductivity and concentration measurement (3000-series)

Valmet offers a portable conductivity analyzer that is an ideal calibration tool on site. Our portable conductivity sensors come with an integrated flow chamber which enables ultrapure water calibrations at the highest precision. Valmet also offers calibrations service for portable analyzers. Multipoint calibration certificates are available for conductivity and temperature.
