MTPS

Modified Transient Plane Source (MTPS) Sensor

Suitable for testing solids, liquids, powders, and pastes. The MTPS sensor offers “Plug & Play” thermal conductivity characterization.

Construction

  • Sealed against dust and liquids by a RTV silicone sealant between housing and sensor chip
  • Housing is made of stainless steel
  • Chip surface is made of alumina (96% aluminum oxide) with a thin sealing glass layer

Environmental – Operating

Operating temperature range for sensor head: -50°C to +200°C (with option to extend to 500°C)

Note:  Sensor does NOT heat sample beyond a couple of degrees.

Relative humidity: up to 95% non-condensing

External: vacuum to 6 Atm (90 PSIG)

Calibration

  • Sensor is factory calibrated and provided in “Plug & Play” format.
  • Calibration data is stored on sensor’s ID chip in sensor connector.
  • Calibration data is verified prior to sensor operation with standard reference materials.
  • Sensors are interchangeable and field replaceable.

TLS NEEDLE

Transient Line Source (TLS) Needle Probe Sensor

C-Therm TLS sensors are suitable for testing a wide range of materials including plastic resins, melts, slurries, pastes, paints, thermal interface materials, foodstuffs, powders and soils. 
 
Test method:  Transient Line Source (TLS)
Standards: ASTM D5334, D5930 and IEEE Std 442-1981
Needle length:  150 mm
Thermal Conductivity Range:  0.1 to 6 W/m.K
Temperature Range for Needle:  -55 to +180 °C 
Accuracy (@ 20 °C):   ± (3% + 0.02) W/mK

FLEX TPS

Transient Plane Source (TPS) Flex

The TPS method employs a double-sided sensor in characterizing the thermal conductivity and diffusivity of materials. TPS provides the user the greatest flexibility and control over experimental parameters and avoids the use of any contact agents. Recommended for more experienced users.

k-range: 0.03 to 500 W/mK

Temperature range: -50 to 300 °C

Sample type: solid

Standard: ISO 22007
