Thermal Validation System

The E-Val Flex thermal validation system is designed for validationapplications that require compliance with FDA guidelines and internationalGMP standards. The E-Val Flex greatly simplifies and correctly documents the entire validation process. The ValSuite™ software keeps a complete database on all aspects of your validation requirements – tracking thermocouples, calibration reports, test setup, data analysis, specific user access, to final compliance reports.

Flexibility For Different Validation Applications
E-Val Flex was designed as a single solution for all thermal validation applications. It can be ran as a stand-alone unit or networked with your PC. The software, which handles up to 128 channels, documents and controls each step reducing errors and maintaining guidelines for more complex regulated applications that require tight compliance control. The easy expandability makes this a complete validation solution for a facility with a variety of applications.
 

Quality
The highest quality electronics were incorporated into the design greatly improving efficiency and accuracy. With 8MB of memory and a battery backup, data will never be lost due to a power outage. Pt-1000 sensors are installed on each individual thermocouple channel eliminating gradient errors through the cold junction dramatically improving accuracy. The case is made in 316 stainless steel ensuring durability and reducing noise in the electronics which makes the unit ideal for the harsh environments on a factory floor.

Accuracy
Dramatic improvements in accuracy with enhanced engineering:

  • Pt-1000 sensors are installed on each individual thermocouple channel eliminating gradient errors through the cold junction
  • Implementation of ID chips enabling factory certification and storage of calibration offsets in each individual thermocouple
  • Use of high quality sealed thermocouples

The E-Val Flex system reduces the need for frequent calibration saving a tremendous amount of time. Competitive systems require calibrations before every study. We recommend running a one point verification test to find any damaged or degraded thermocouples. If you need to replace a damaged thermocouple a system calibration is not required. Since the Ellab type T thermocouples are pre-calibrated and hold the offsets in the ID chip, a 0.05°C accuracy is held.

E-VAL FLEX MODULES

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.

Ellab_val-eflex
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 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 and is independent from the number of channels.

Ellab Smart Thermocouples

The E-Val Flex modules are designed for Ellab premium grade type T, 7 strandthermocouples. As a new feature, the Ellab thermocouples are now equipped with an electronic ID and memory for calibration values.

E-Val PRO-application-01

The fact that Ellab has incorporated an identification chip in the jack plug of each thermocouple dramatically improves the specified accuracy (±0.05°C) and ease of thermocouple identification.

The internal chip identifies specific thermocouples with a serial number and contains calibration offsets that can now travel with the thermocouple. This enables easy management of thermocouple locations, historical calibration data and easy replacement during process runs.

The software database keeps a complete record of usage which is a tremendous advantage in keeping track of NIST traceability and calibration history for compliance. The serial number is displayed on the jack plug and probe tip making it extremely easy to identify where each thermocouple is positioned resulting in tremendous time savings during setup.

Reduce Replacement Frequency and Maintenance Costs
Ellab thermocouples are either PTFE sealed wires for distribution tests or silicone with a variety of stainless steel probe tips for penetration studies. The superior quality results in longer and more stable performance reducing replacement frequency while saving time and maintenance costs. Ellab thermocouples use jack plugs which stop moisture regression into electronics improving accuracy and durability. Jack plugs are very simple to plug into the module and do not require the setup time of screw terminal systems.

High Precision Thermocouple Probes
Often high quality thermocouples are overlooked when purchasing

a temperature monitoring system. Using high quality probes dramatically improves accuracy, stability and the rate of success. Often money and time are wasted trying to calibrate or locate problems with inferior thermocouples. Why risk it when many of your maintenance problems can be solved with a quality probe?

Ellab develops and manufactures a wide range of probes for various applications.  The list of probes includes multipoint probes with 4 to 10 measuring points, probes for frozen applications, high temperature probes, special probes for liquids and air, probes for hot air ovens, steam sterilizers and autoclaves, etc. Our standard probes are supplied with threads that fit into packing glands which form a no-leaking seal into packages or cans.

 

Electrodes
The material of the electrode can be stainless steel, polyxymethylen, or PTFE. Stainless steel electrodes are more durable and preserve better stability than standard thermocouples, reducing maintenance time and replacement costs. Depending on the application, it is possible to choose the design of the electrode to be either round, sharp or conic.

Cables
The cables are generally sold as a standard 7 meters long, but the length can always be customized for a specific application. The cable can be delivered with silicone, PTFE or mineral insulated stainless steel. The PTFE cables are intended for applications where space is limited, such as feed-throughs in autoclaves.
