Pressure-Measuring Module Qmix P

Pressure Measuring Modules

Pressure-Measuring Module Qmix P

For 2-channel Pressure Measurement

The Qmix P pressure-measuring module offers two independent pressure sensors, which can be configured for different pressure ranges (20, 50, 100 or 200 bar). The pressure sensors can monitor pressure values within a system or, utilizing the software, they can be used to create pressure control circuits, to facilitate pressure-controlled dosing, for example.

The pressure sensors can be used in any flow direction. You can decide which of the connections act as intake or outlet. Cleaning the sensor is easy. Simply rinse it with a rinsing solution.

Technical Data

  • Pressure sensors: 20, 50, 100 or 200 bar, max. over-pressure = 100% (1 minute maximum)
  • Inside volume: ≈115μl @ ≤50bar, ≈60μl @ ≥100bar
  • Fluidic connections: ¼“-28 UNF

Pressure-Measurement Modules for neMESYS and Qmix Systems

Pressure Measurement, Pressure Monitoring, Safety Shutdown and much more

Qmix P Modules let you expand your existing neMESYS dosing system or your existing Qmix flow-chemistry system by adding a pressure measurement function, quickly and easily. Using the neMESYS interface and the neMESYS plug system, you can combine multiple pressure measuring modules or add additional modules, such as tempering modules or valve modules. Pressure-measurement modules help you monitor system pressure levels. In combination with QmixElements pressure monitoring, you can use Qmix P modules to shut down pumps automatically when critical pressure levels are exceeded or undercut.

QmixElements I/O-Plugin

All I/O Channels at a Glance

The QmixElements I/O plugin enables fast and easy access to all analog and digital in- and output channels in your Qmix system. You can select the description, scaling, the icon and the unit for each channel. This lets you adapt the display of channels to your application in the optimum way.


  • Individual description and scaling (factor & offset) for each channel
  • Real-time recording of sensor data
  • Script functions for the automation of processes

QmixElements I/O-Plugin Scripting

Automating Processes and Actuating External Devices

Triggering Events, Converting measurement values, Monitoring measuring ranges…

Like all other devices, analog and digital I/O channels are integrated into the QmixElements scripting system through the respective scripting functions. You can load analog sensor values or send analog signals. You can trigger certain processes through external signals or synchronize your process with external devices using trigger signals, thanks to the script system. Do you want to control the flow rate of a pump in real time, using an analog input signal? You can program that too in just a few minutes, through drag&drop.

Recording Sensor Values in Real-Time

Visualize, Analyze, Optimize…

In QmixElements you can record the values of all analog and digital inputs and outputs in the form of curves or CSV-files. This lets you visualize temporal changes of process data or connected sensors (pressure, temperature, etc.) live and in real-time. You can configure the recording through drag & drop and save diagrams in various different formats (PNG, JPG, PDF…). Using CSV-files, recorded measurement values can be analyzed or graphically processed conveniently in Excel or any other analysis program of your choice.

QmixElements Software

QmixElements Software

Laboratory automation platform

The QmixElements software is a comprehensive, plugin-based, modular software solution for the control of all cetoni devices via a common graphical user interface. The software consists of a core that provides the basic features and services, such as the application window, the event log or the tool bar.

Qmix SDK Analog I/O Library

Windows 32-Bit / 64-Bit DLLs

You can read analog inputs of Qmix I/O modules, analog pressure measuring inputs of the Qmix P modules or the analog inputs of neMESYS syringe pumps with one uniform interface used across all devices – the analog I/O library. All functions are supplied through a Windows DLL (32-bit / 64-bit), enabling simple and inexpensive integration into any 32 or 64-bit Windows development environment supporting the use of DLLs.

Some of the things you can do:

  • Write analog outputs
  • Read analog inputs
  • Configure the software scaling of measuring parameters

Qmix SDK Analog I/O Library LabVIEW VIs

Qmix SDK Analog I/O LabVIEW Kit

Full LabVIEW Integration

The LabVIEW kit lets you integrate the Qmix SDK analog I/O library into your LabVIEW environment with minimal effort. You will be provided with a selection of finished VIs to access analog inputs and outputs of Qmix modules.


  • Clearly laid out grouping and color coding of VIs according to their function
  • Can be used with all other Qmix SDK libraries (pump, valve, motion control...)
  • LabVIEW-conformant troubleshooting
  • Sample VIs for quicker introduction
  • Supports 32 and 64 bit LabVIEW versions

Qmix SDK

Qmix Software Development Kit (SDK)

For integration of cetoni devices into custom applications

The Qmix SDK is a powerful software package that allows developers to integrate their Qmix system and its various modules into their applications. Central to the Qmix SDK are device-specific libraries that provide the programming interface (APIs) for each Qmix module (neMESYS pumps, rotAXYS and neMAXYS positioning systems, Qmix IO, etc.).
