Touch screen, easy to use

The conductivity transmitter features an integrated graphical LCD display with 3 different backlight colours. Conductivity (µS/cm or mS/cm), concentration (%), temperature (°C) and also the customer-specific medium name are conveniently indicated for on-site control for safe operation, especially for manually operated cleaning systems. It is quickly configured on the spot without a computer using the touch screen. It can be programmed to four measuring ranges, which can be easily adjusted from the touch screen. Precise control of temperature compensation is also possible from the display, which makes the Alfa Laval conductivity sensor ideal for a wide range of conductivity measurements.

All stainless steel and PEEK, hygienic design

Alfa Laval Conductivity Transmitter are highly accurate and hygienicly designed, measures the ability of process liquids to carry electrical currents.

All wetted parts are made of AISI 316L stainless steel and PEEK, and designed to withstand process temperatures between -20 and +150°C. Because the conductivity sensor can withstand high temperatures, it is well suited for use in Cleaning-in-Place (CIP) and Sterilization-in-Place (SIP) processes. These compact 3A-certified sensors may be installed in pipe sizes DN40 and larger.

High accuracy, fast response

Thanks to optimized flow geometry and fast response time, Alfa Laval Conductivity Transmitter are particularly suitable for applications that require the separation of media and/or the measurement of cleaning agents in Cleaning-in-Place (CIP) equipment. Measurements are highly accurate even at very low conductivity and flow rates.

Remote controllable, easy to use

The conductivity transmitter come with four standard pre-configured measuring ranges, which can be easily adjusted from a remote location. Precise control of temperature compensation is also possible from a remote location, which makes the Alfa Laval Conductivity Transmitter ideal for a wide range of conductivity measurements.

An integrated display indicates values for mS/cm and °C, which instantly provides users with monitoring and control data required for safe operation, especially for manually operated cleaning systems.

How it works

Operating principle

Inductive conductivity measurement is based on the principle of a transformer. An AC voltage generator controls the primary side of the transformer. The liquid flows through the channel bore in the measuring head and forms a conductor loop, which links the primary side of the transformer and the secondary side of the transformer. The measuring cell is a homogeneous sealed body all in PEEK. Through the body is a hole, through which the media is flowing. Built-in around the hole are two coils; a primary coil supplied with an AC voltage and a secondary coil, which picks up a small signal through the media inducted voltage. The size of this voltage is dependent on the conductivity of the media. This signal is handled and amplified in the electronics to a linear analogue 4...20 mA output signal.

Also built into the body is a Pt100 sensor placed in the tip of the sensor. This is measuring the media temperature to enable temperature compensation of the conductivity signal, which is very temperature dependent. The Pt100 sensor signal also features as a seperate analogue 4...20 mA output signal.

The coils and sensor are encapsulated in the PEEK sensor body, which have a surface with surface roughness (Ra) <0,8 µm. It is therefore well suited for use in hygienic processes or directly in concentrated acids or alkalis.
