TCMS is an electronic system to measure the thermal conductivity of solid and liquidpropellant specimens. The system functions on 'Transient Hotwire' technology where acopper/platinum wire is used as the primary sensor element for measurement. TCMS iscapable of detecting nano-volt level signals from the sensor element when it is excited by aninbuilt constant current source with micro-ampere level accuracy and stability. The thermalconductivity of liquid propellant is an important parameter to determine its usability as fuel forvarious stages of rocket propulsion.

• Multi-channel (8 channels)
• 32-bit DAQ system with < 500nV sensitivity
• Constant current source with < 100?A error
• Application software for display, recording, replay & analysis
