MIL Standard Dust Test Chamber
The 1000L Dust Test Chamber simulates dusty environment to validate the reliability and functioning of specimen under extreme environment. Being an ideal option for testing electronics and automotive components, the chamber’s dust composition, dust concentration levels, test duration and dust injections, controlled air velocity to the test space are exclusively designed to comply with the MIL-810F test standard procedure I and procedure II.

The interior of the chamber is built with 304 grade stainless steel treated for erosion resistance and high temperature application to avoid creep failure. The exterior body is made of GI with electrostatic powder coating offering high wear resistance. It’s all systems as well as the sub-systems are shielded to provide protection from sand and dust particles. The test space is fitted with externally controlled turn table to rotate the specimen in any direction which could bear a weight up to 150 kg. The viewing window in test space is provided with wipers for user to view the specimen under testing.

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
