AGREE Chamber

Users widely endorse CME's Vibration and Temperature environmental chambers with Lifting test space due to their adaptability to various shakers and test mode combinations involving high temperature, low temperature, and humidity. These environmental chambers, tailored to specific specifications, are designed for combined Vibration Temperature and Humidity tests.

Overview

CME's Vibration and Temperature environmental chambers for Lifting test space are highly praised by users for their adaptability to various shakers and test mode combinations, including high temperature, low temperature, and humidity. These chambers, designed according to specific requirements, are dedicated to combined Vibration, Temperature, and Humidity tests.

With the increasing vulnerability of smaller electronic devices to vibrations in diverse operating and installation environments, the importance of electrical device vibration testing has grown. Combined-environment testing involves combining vibrations with various environmental stresses, such as low-temperature, high-temperature, or high-temperature/humidity environments, to recreate conditions closer to actual operating environments.

The test volumes of these environmental chambers are optimized based on the geometry, nature, mass, and dissipation of the product being tested, while using a vibrating element. These chambers comply with adapted standards and the manufacturing process is flexible enough to build environmental chambers set on motorized lifting test space. The shaker can be fixed, and the environmental chamber can be positioned on top of it, associated with a lateral transfer system.

To meet these requirements, our manufacturing process integrates the drawer principle, equipped with a head expander that ensures tightness between the shaker and the environmental chamber, which can be adapted to several shapes.

These chambers comply with a variety of MIL-STD, ASTM, and other test standards.

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
