MemoRail A1401

Compact. Cost-efficient. Digital. Plug and Measure with the new analyzers for Memosens


• Modular housing, 12.5 mm wide
• Measurement of pH value, ORP, conductivity, oxygen and temperature
• Memosens communication
• 2 current outputs 4 to 20 mA, active or passive
• 24 V DC power supply (screw terminals or bus connection) or
VariPower broad-range power supply, 90 to 230 V AC
• Simple configuration via DIP switches
• LEDs report operating and sensor states

MemoRail is the first genuinely compact, digital analyzer for measuring pH values, ORP, conductivity, oxygen and temperature with Memosens sensors. Two analog active / passive 4 to 20 mA outputs supply the measurement values for process value and temperature to the process control system or a PLC.


Plug & Measure
MemoRail is immediately ready for measurement on connecting a precalibrated Memosens sensor. “Used” sensors can simply be replaced.

Optimum availability of the point of measurement is achieved by using precalibrated sensors with contactless Memosens technology. Calibration is no longer carried out on site but under reproducible conditions in the laboratory with the new MemoSuite software tool. Separate sensor data are always directly assigned to each Memosens sensor. Problems at the connector involving humidity, corrosion or even defective galvanic isolation are a thing of the past.

The highly space-saving modular housing of the MemoRail devices is only 12.5 mm wide.

With its simple configuration via DIP switches, MemoRail is set up only once for the measurement parameters and ranges. For precise adjustment to the application, a range of variants is available, including models with one or two analog current outputs which can be active or passive. The unit is supplied with 24 V DC via screw terminals / bus connec-tors or with 90 to 230 V AC via the integrated VariPower broad-range power supply. LEDs report operating and sensor states.

The outstanding properties of MemoRail enable the implementation of measurement stations with low overall costs, especially in combination with modern Memosens sensors specially tailored for use with MemoRail.

MemoRail offers economical alternatives in applications such as:
– drinking water
– wastewater, sewage plants
– aquaria, fish farms, greenhouses
– fermentation
– rinsing equipment
– car wash systems
– water treatment plants/equipment
Furthermore, with its narrow modular housing, MemoRail is perfectly suited to installation in restricted spaces – e.g. in control cabinets, fermenters, or on ships.

MemoRail supplies power to the Memosens sensors and converts the digital measuring signals into output currents of 4 to 20 mA for connection to the process control system or to a PLC.

Calibration, diagnostics, documentation
MemoSuite calibrates Memosens sensors. Additional functions are the sensor diagnostics and database documentation. MemoLink establishes the connection between Memosens sensor and PC.

The Software Tool

Fast and user-friendly
The MemoSuite software enables reproducible calibration of Memosens sensors in the laboratory. Calibration under adverse ambient conditions on site is no longer necessary. The only thing required there is the quick und uncomplicated replacement of the sensors for precalibrated sensors.

MemoSuite Basic and MemoSuite Advanced meet different application-specific requirements:

MemoSuite Basic calibrates Memosens sensors.
In addition to calibration,
MemoSuite Advanced also executes diagnostics and database documentation of the sensors.
The database complies with the requirements of GMP and FDA CFR 21 Part 11.
