Can sensors with Memosens technology be used without hesitation in environments with high humidity levels, without any distortion of the measured values?

Yes, they can be used without hesitation. This is because the system is completely resistant to moisture, as both electricity and data are transferred inductively, i.e. via a non-contact connection. The connection itself is hermetically sealed.

How long does on-site calibration take?

You can be sure that you will not need to carry out an on-site calibration. You only need to replace the sensor - and this is done in a tenth of the time required for the calibration of analog sensors. This means that system downtime is reduced to a minimum. Calibration itself is carried out in a laboratory under optimum conditions.

Must the sensor be replaced on site by specialized personnel?

No. Replacement is so easy that it can be done by any member of staff.

fold faq

Does calibration in the laboratory have an effect on the measurement performance in the field?

No. Thanks to the complete galvanic isolation, the properties of the cable and transmitter no longer play a role.

fold faq

Can Memosens store process data?

Yes. Memosens sensors have an operating hour counter and they store high temperatures, extreme pH values, sterilizations, calibration values and changes to these values.

fold faq

Is predictive maintenance possible?

Yes. In combination with suitable transmitters, functions such as calibration timers or sudden change of slope or zero point can be used for predictive maintenance.

fold faq

Do Memosens sensors have a longer service life than analog ones?

Yes. This is because they are usually cleaned, reconditioned and calibrated in the laboratory, after which they are again ready for use.

fold faq

Is a Memosens measuring point more expensive than an analog measuring point?

No. The costs are about the same. The slightly higher price of the Memosens sensors is offset by the significantly less expensive wiring.

fold faq

Is there a difference between the analog and Memosens sensors in terms of accuracy and reproducibility?

No. As the sensor elements are identical, there are no differences whatsoever.

fold faq

Can analog measuring points be converted to Memosens without any problems?

Yes. For suitable transmitters, only a new input card and new wiring are required. The Memosens sensors are completely compatible in terms of dimensions, threads etc.

fold faq

Memosens sensors contain electronic components. Can they be used in potentially explosive atmospheres?

Yes. They have ATEX Zone 0 approval. The following Ex approvals have also been attained: FM, CSA, Nepsi and TIIS.

fold faq

Is Memosens susceptible to magnetic fields due to the electronic components?

No. They provide interference-free performance, even in chloralkali electrolysis plants. Of course, they fulfill the EMC standard EN 61326: 2006.

fold faq

Does the plug-in head offer safe and reliable sealing of the process in case of glass breakage?

Yes. The plug-in head seals up to 16 bar with triple safety. This is confirmed by the TÜV certificate.

fold faq

Is Memosens established and accepted on the market?

Yes. Over 200,000 Memosens sensors have already been sold.
