CME’s Walk in chambers are designed for simulating, monitoring & control of environmental conditions like temperature & humidity. All these chambers are double walled & modular in construction, easy to assemble at site. They are available in standard sizes & can also be tailor made to suit specific requirements. Forced air circulation with the help of fan blower maintains uniform conditions. Use of intelligent control systems & dedicated software requirements greatly enhances the performance. These chambers can be provided with standby refrigeration & humidity systems (optional) for uninterrupted functioning.
Types of Flooring
Step-In Flooring
The Walk-In chamber is built on an existing floor with insulation of 150 mm – 200 mm. Step-In flooring is ideal for those testing applications where the test specimen is light in weight and offer easy mobility in placing it inside the test space.
Step Less Flooring
For the whole vehicle testing or to conduct test on a heavier specimen, the Step Less flooring is used as it will be easier to drive them from the ground to the test space. The floor is seamless made by inserting wall panels into it and is insulated from underneath.
Got Technical Question!
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
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
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
Power Resumption Modes
In case of a power failure, option of conditional restart based on temperature/time or continuous
Diagnostics
Event viewer will display a log of all errors/actions with a date and time stamp PLC inputs and outputs status will be indicated
Service Monitor
Log of critical components life cycle with a predefined life cycle time and elapsed time in hours
Delay Start
Real time clock based, delayed start function
