E-Val Flex System Description

The E-Val Flex modules are available with 8 or 16 type T thermocouple channels, and the master modules have additional channels for digital pressure and deflection.

The master module works as a stand-alone or as network master. When the module has been setup and started, the PC can be disconnected and removed from the production area. Later when the process is complete, the module is reconnected and the data is downloaded to the PC.

Real-time data can be viewed on the PC or via the LCD screen on the module. Input keys on the module allow you to scroll through different channels or historical readings. These keys can also be used to manually start or stop a study on the production floor if running without the PC.

Non-volatile memory in all modules stores data that has not been transferred to the PC in case of power failure or loss of connection to PC. The 8 MB memory is sufficient for a minimum of 8 hours using 16 channels with sampling every second for each channel.

The RS485 port on the master module allows for easy, inexpensive pressure measurements. Multiple pressure sensors can be connected to the same RS485 port.

The sampling rate can be set from 1 second to 24 hours, which is independent from the number of channels. The fastest sampling rate is once every second for each channel. The modular design of the E-Val Flex allows for these capabilities.

Ethernet or Wireless Network
The E-Val Flex modules are connected together and to the PC through a standard Ethernet network, and each module's sample data is independent from the other modules. The ValSuite™ software and the E-Val Flex hardware can handle up to 128 active channels. Ethernet is the world wide standard for local area networks (LAN) and is utilized by many companies. Ethernet enables fast and reliable data transmission over long distances, and it is not affected by noise. If a cable to one module malfunctions the rest of the modules will still be working.

The modules can communicate through a standard Ethernet connection to your PC. If a wireless network is available, a standard transmitter can be placed on the module for wireless communication. The open network configuration is a tremendous advantage, because it can run on currently installed networks or wirelessly where running wiring is troublesome.

Stand Alone or Control Via PC
Once the module has been started it can be disconnected from the PC and moved out to the production floor. It is possible to see parameter values on the LCD display.
