Technical Information

Indumax CLS54D

Hygienic inductive conductivity sensor for applications in the food, beverage, pharmaceutical and biotech industries

Application

The CLS54D conductivity sensor is specifically designed for use in hygienic applications in the food, beverage and pharmaceutical industries and in biotechnology. Thanks to its hygiene certificates and its food-safe, virgin PEEK design without any joints or crevices, it meets the strict demands of these industries. The CLS54 is ideal for:

• Phase separation of product/water and product/product mixtures in pipe systems

• Control of cleaning in place (CIP) processes in the return line

• Concentration control in the remaking of CIP cleaning agents

• Product monitoring in pipes, bottling plants and quality assurance

• Leakage monitoring in the following industries:

• Dairies

• Breweries

• Beverages (water, juices, soft drinks)

• Pharmaceuticals and biotechnology Use with Liquiline CM42, CM44x and CM14 transmitters.

Your benefits

• Unique hygienic design, therefore no risk of recontamination

• Has all the process connections commonly used in the hygiene sector

• Fast measurement with temperature response time t90 under 26 s, ensuring safe and efficient phase separation

Other advantages of Memosens technology

• Maximum process safety

• Data security thanks to digital data transmission

• Very easy to use as sensor data saved in the sensor

• Recording of sensor load data in the sensor enables predictive maintenance

Measuring principle

Measuring system

Inductive conductivity measurement

An oscillator (1) generates an alternating magnetic field in the primary coil (5), which induces a current flow (4) in the medium. The strength of the current depends on the conductivity and thus on the ion concentration in the medium. The current flow in the medium, in turn, generates a magnetic field in the secondary coil (3). The resulting induced current is measured by the receiver (2) and used to determine the conductivity.

Advantages of inductive conductivity measurement:

• No electrodes and therefore no polarization effects

• Accurate measurement in media with a high degree of pollution and a tendency to form buildup

• Complete galvanic isolation of the measurement and the medium

A0024926

A complete measuring system consists of the following components at least:

• The CLS54D inductive conductivity sensor

• A transmitter, e.g. Liquiline CM44x

Communication and data processing

Communication with the transmitter

Always connect digital sensors with Memosens technology to a transmitter with Memosens technology. Data transmission to a transmitter for analog sensors is not possible.

Digital sensors can store measuring system data in the sensor. These include the following:

• Manufacturer data – Serial number – Order code – Date of manufacture

• Calibration data – Calibration date – Cell constant – Delta cell constant – Number of calibrations – Serial number of the transmitter used to perform the last calibration

• Operating data – Temperature application range – Conductivity application range – Date of initial commissioning – Maximum temperature value – Hours of operation at high temperatures

Reliability

Maintainability

Integrity

Dependability

Memosens technology digitizes the measured values in the sensor and transmits the data to the transmitter via a . The result:

• Automatic error message if sensor fails or connection between sensor and transmitter is interrupted

• Immediate error detection increases measuring point availability

Easy handling

Sensors with Memosens technology have integrated electronics that store calibration data and other information (such as total hours of operation and operating hours under extreme measuring conditions). Once the sensor has been connected, the sensor data are transferred automatically to the transmitter and used to calculate the current measured value. As the calibration data are stored in the sensor, the sensor can be calibrated and adjusted independently of the measuring point. The result:

• Easy calibration in the measuring lab under optimum external conditions increases the quality of the calibration.

• Pre-calibrated sensors can be replaced quickly and easily, resulting in a dramatic increase in the availability of the measuring point .

• Maintenance intervals can be defined based on all stored sensor load and calibration data and predictive maintenance is possible.

• The sensor history can be documented on external data carriers and in evaluation programs. Thus, the current application of the sensors can be made to depend on their previous history.

• Measured values cannot be distorted by moisture.

• EMC safety provided by screening measures in digital measured value transmission.
