MC EndressHauser Next Gen Memosens 2.0 Liquid Analysis Sensor 1 400

Endress+Hauser’s Memosens technology revolutionized liquid analysis. It converts the measured value to a digital signal and sends it inductively to the transmitter, offering safe data transfer for increased availability of the measuring point and trouble-free processes. Now, with the introduction of Memosens 2.0 sensors for pH/ORP, conductivity and dissolved oxygen, those liquid analysis measuring points are future-proof and IIoT-ready ready, offering a range of potential additional benefits, like a data foundation for predictive maintenance. Endress+Hauser plans to extend the technology to its entire sensor portfolio for liquid analysis.

Memosens 2.0 technology, like the well-proven first generation Memosens, is suitable for all industries where liquid analysis is required. It is backwards-compatible and can easily be integrated into existing systems.

Unlocking the potential of measurement data

Memosens 2.0 sensors store numerous, relevant data such as operating hours, minimum and maximum temperatures and measured values, calibration histories and load matrices. This data can be used and processed for comprehensive analysis and more precise process management. The sensors also provide a perfect basis for predictive maintenance strategies with Endress+Hauser’s Heartbeat Technology and enhanced IIoT services via the Netilion cloud ecosystem.

Non-contact digital data transmission eliminates the effects of moisture, corrosion and salt bridges with alert messaging if the signal transmission is disturbed. Galvanic isolation ensures interference-free measurement and EMC safety. The Memobase Plus software provides full traceability of all sensors used, supporting operations according to strict guidelines of regulated industries.

Reducing operating costs

Since Memobase 2.0 sensors are equipped with highly integrated electronics, they can be calibrated and adjusted under lab conditions favorable for the operator and stable for precise results. Field replacement is easy and quick – a labour cost saver – thanks to the lockable bayonet connector and automatic sensor identification by the transmitter. Other cost savings will continue to accrue over time. For example, using pre-calibrated sensors reduces process downtime. Regular regeneration extends sensor lifetime. Lab calibration reduces the stand-by hours for analysis experts.

Memosens 2.0 also offers error-free flexibility for measuring points in hazardous areas, since all Ex-rated sensors can be connected to all Endress+Hauser transmitters with the respective approval.

MC PepperlFuchs Monitoring Condition of Plants w Vibration Sensors 3a 400

To enable long-term monitoring of vibrations, Pepperl+Fuchs recently launched a new portfolio of vibration sensors. You can find out what distinguishes these products in the following blog article. Using a wind turbine as an application example, we will also show you how you can use vibration and acceleration sensors in combination to keep an eye on both long-term and short-term changes in vibration.

The portfolio of vibration sensors

Pepperl+Fuchs has recently started offering a range of vibration sensors to perform reliable measurements of vibration velocity and acceleration in low or high frequency ranges. Compared to similar products, Pepperl+Fuchs’ vibration sensors have approvals up to SIL 2, a large measuring range of up to 128 mm/s, and automatic condition detection for ball bearings. Due to their robust housing and encapsulated electronics, the sensors impress with maintenance-free operation and a particularly long service life.

The three designs in the portfolio are available with different certifications and approvals. In this way, you can find the right vibration sensor for every application:

  • VIM3 series: The compact VIM3 series is suitable for applications up to SIL 1/PL c, and has output options for analog or IO-Link.
  • VIM6 series: The VIM6 series is approved for hazardous areas up to Zone 1/21. With an extended temperature operating range of -40°C … +125 °C, the sensors are ideal for high-temperature areas.
  • VIM8 series: Due to a particularly robust housing made of duplex steel, the vibration sensors of the VIM8 series are designed for use in offshore applications as well as in harsh and hazardous areas of Zone 1/21. Moreover, the sensors have an approval up to SIL 2/PL d.


Vibration sensors vs. acceleration sensors

Not only vibration sensors, but also acceleration sensors from Pepperl+Fuchs are used to measure changes in vibration: Both record the vibration acceleration in g. Nevertheless, the sensors differ in their technical operating principle and are therefore each suitable for different applications.
