Thermal Chamber

The thermal chamber is equipped with the latest simulation technology to provide customers with an unparalleled testing experience. The chamber features a highly responsive touchscreen controller (Envicom Graphite Series) with a wide range of features, including Chamber Analytics, On-demand cooling, on-screen diagnostics, and safety alarms. It also integrates with networking ports such as Ethernet, RS 232, RS 485, and a 2GB SD card for test data storage. Additionally, the chamber can be integrated with third-party software such as NI/LabVIEW.

Overview

The series of thermal chambers is an ideal choice for conducting cyclic tests involving low and high temperatures as well as humidity. These chambers are renowned for their exceptional quality and reliability, ensuring they can fulfil the rigorous testing requirements of various international standards such as ASTM, IEC, MIL, DIN, and more.

CME provides support for testing the effects of temperature and humidity on your products' properties, functionality, and lifespan. These tests are conducted under reproducible, certified, and accelerated conditions.

Engineered by CME's global R&D team, these chambers are designed using state-of-the-art simulation technology to deliver an unparalleled testing experience. They are equipped with a highly responsive touchscreen controller (Envicom Graphite Series) that offers a wide range of advanced features including Chamber Analytics, On-demand cooling, onscreen diagnostics, and safety alarms. Moreover, they come with networking ports such as Ethernet, RS 232, RS 485, and a 2GB SD card for storing test data. These chambers also offer integration with third-party software such as NI/Lab view.

Controller

Communication

Ethernet

Ethernet capability to remotely monitor and control the chamber.

USB

USB Type-A host port to connect a keyboard or mouse or download CSV data via pen drive [max 2GB] USB Type-B data port for connection to PC for software upgrade and access memory card storage

Web Server

Built-in web server allows remote view or control from any internet connected PC, tablet or smart phone

NI Lab view

The communication which used is MODBUS RTU protocol, which is an international standard for communication in process instrumentation and automation. Necessary changes to be made in the user’s software to communicate this in MODBUS RTU universal protocol. This feature can be used manual mode only.

Hardware

Enhanced with modular controller integrating multi-zone PID control and data acquisition. SIMATIC programmable logic controller. Touch screen controller, PLC and other controller components are of a generic make with an OEM software. Free software upgrades up to one year.

Memory

SD card of 2GB memory will store all the test program data and also the diagnostic data. This card is accessible by USB and Ethernet.

Digital Events

1 digital output for switching test specimen via potential free contacts, load max. 24 VDC, 5A

Programming & Report Generation

Programs

99 independent programs can be stored with name and number. Each of these programs have segments which can be looped to a previous segment and repeated up to 999 cycles, creating almost unlimited number of segments The chamber can be operated in manual mode, where the set point can directly be changed in the home screen The ramp rate can be set as a value in °C/min or ramp time Graphical representation of the temperature program The time is logged only when the set valve is within the band.

Trend Graph

Real time trend graph for temperature set value, temperature process value, humidity set value and humidity process value. Options of zoom in/out, pan and individual plot selection

Safety & Security

Security

Multi level security of guest, user, admin and factory level users with individual password protection All settings can be reset to factory defaults using admin login

PID

6 zone based PID’s with auto recall of PID based on type of program, segment and zone can be set. Each of these PID’s can be set by using the auto tune feature or manually based on user’s requirements.

Process Mimic

Graphical representation of the working of the chamber, with live status of all the components, including the current temperature/humidity process values, compressor suction/discharge pressures and return gas temperature
