Reliable Inductive Measurement, EHEDG certifiable with Clamp Connection
Insatech offers a smart solution with external temperature sensor to battle your problems with conductivity measurements. Using an inductive conductivity sensor with a termowell welded to the clamp, an external temperature element registers the media’s change in temperature instantly, which provides optimal temperature compensation in the process.
In terms of calibration, the workflow is significantly optimised, as time, and there by money, is saved by minimizing unnecessary stabilisation time. Another advantage will be achieved, if the conductivity sensor is used for calculation of concentration, of for instance NaOH (Sodium hydroxide / cleaning reagent), which will provide a more accurate dosage control, and ensure an optimum quality of the cleaning procedure. Our solution is EHEDG certified (European Hygienic Engineering & Design Group), which means it may be used in applications requiring the use of hygienically approved equipment.
Inductive conductivity measurement – special flow fitting for small pipes
In pharmaceutical production we often see very small pipes. Measuring the conductivity is typically done to control the CIP processes; however this creates a problem due to lack of space for the inductive sensor, which usually requires a pipe with space for a sensor with the diameter Ø50. To overcome this problem Insatech has designed a flow fitting*, which ensures the possibility to connect the sensor to small diameter pipes.
* Using this type of solutions requires the calibration to take place in the process to secure future measurements of conductivity are correct.
So, What is Conductivity So Important to Measure?
In the pharma industry, the production requirements are subject to a high degree of control. The measurement of conductivity is an important parameter in order to validate production- and process control. As conductivity is inseparably related to temperature, a fast and stable measurement of temperature is an important element in the process.
The Trouble of Temperature
A temperature measurement via an inductive conductivity sensor is stable when the process temperature is stable, since the temperature element is built into the peek material of the sensor. Therefore, if the production temperature varies, for instance during SIP/CIP, which can be both rapid and large, the temperature takes time to penetrate the PEEK material, and a delay will often be seen.
This delay may result in a substantial change in conductivity before the temperature deviation is detected, which will have serious consequences in a production, with high demands for accuracy of the measurement.
Time Consuming Calibrations
Another problem arises when the temperature needs to be calibrated in an entire area, for instance from 0-100 degrees. In this scenario the standard solution becomes considerably time consuming. We know, based on the experience of our calibration technicians that this procedure is lengthy, as the temperature of the media must be increased gradually and stabilised, before the new temperature can be verified.
Don't Gamble with Consequenses
Consider the implication of temperature deviations and their effect on conductivity. How much change in conductivity is allowed at your production site before it has consequences? In this respect the XT4 leverages a number of challenging areas in the process which are both time consuming and costly if not handled with care.
