Precisely control and monitor vacuum pressure and flow with the MultiCon CMC99. This versatile datalogger offers PID control, 4-20mA inputs, and USB data transfer for comprehensive vacuum testing.

The MultiCon CMC99 is a highly versatile and capable instrument, perfectly suited for demanding applications like vacuum testing in quality labs. With its modular design, the CMC99 can be tailored to precisely match the needs of various test setups. Equipping the CMC99 with a 4-20mA input module allows it to seamlessly integrate with vacuum and flow transmitters, providing accurate pressure and flow readings. Simultaneously, a dedicated output module enables control of a vacuum regulator, ensuring precise pressure regulation throughout the testing process.
A key strength of the CMC99 lies in its PID control functionality. This allows for the establishment of a closed-loop control system, where the CMC99 continuously monitors the vacuum pressure and dynamically adjusts the regulator to maintain the desired setpoint. This ensures stable and accurate vacuum conditions within a test rig, crucial for obtaining reliable and repeatable test results.
Data logging capabilities are essential for in-depth analysis and documentation of vacuum tests. The CMC99 offers both onboard data storage and convenient data retrieval options. The optional front panel USB port facilitates quick and easy transfer of logged data to a USB memory device. This allows for convenient movement of data to a PC for further analysis without the need for a direct computer connection.
For more comprehensive data management and analysis, the included DAQ Manager software provides a powerful toolset. After installing the software on a PC, users can easily download historical data from the CMC99. The software enables visualization of trends, identification of anomalies, and generation of reports, providing valuable insights into vacuum testing processes.
The modular design of the CMC99 extends beyond the input and output modules. It offers a range of power supply options, including both DC and AC, allowing for seamless integration of the CMC99 into existing lab infrastructure. Furthermore, communication options like Ethernet provide flexibility in how users connect and interact with the device.
