DIL 402 Expedis Classic and Select – Dilatometry Redefined

The new DIL 402 Expedis Classic dilatometer is a reliable, user-friendly device. The innovative NanoEye measuring cell, which adds a new level of precision and range measurement, is a feature of every instrument in the DIL Expedis series.

Ease of Use

The first step in major simplification is to prepare the measurement using operator-defined method-based test routines. Using a special motion akin to a tail, the MultiTouch feature positions the sample in the ideal location.

The initial sample length is then chosen automatically using a specified contact force. Cushioning ensures the furnace closes smoothly and the sample location remains steady. Exchanging the furnace is straightforward and does not require any prior knowledge. Only a few clicks are required to begin the measurement.

All-In-One Design

Users can purchase a single or dual/differential DIL 402 Expedis Classic system. All of the hardware elements often required for accurate dilatometer readings are included in the all-in-one design of both models. Neither an external chiller nor a cumbersome wire tangle are necessary.

Long Life Cycle

Expedis Classic facilitates efficient production flow with its long lifespan, low workload, simplified and safe operation, and lack of maintenance requirements. The sample holder system can be easily exchanged without any chance of distortion, thanks to the system's clever design.

Best Sample Conditions

Exact measurement results depend on a defined atmosphere created by superior insulation and gas-tight design. The integrated gas flow device and gas-tight design achieve ideal measurement conditions.

The sample compartment and measuring cell can be used to direct the gases. Furthermore, the sample compartment’s insulation prevents temperature variations not influenced by the surroundings.

Controlled Contact Force

The operator can measure small, delicate, fragile, or foamed samples without risk of breakage or non-reproducible deformation by maintaining a constant contact pressure throughout the measurement duration.

This feature also makes it possible to measure sample length extremely consistently, regardless of the operator. This will also prevent sticking-slip effects, rolling and sliding friction, and other issues in the measurement system.

Temperature Measurement to the Point

The thermocouple can be easily adjusted to measure different sample lengths. The thermocouple is supported by a guiding rod, which allows it to be moved into the required position without bending.

NanoEye Observes the Sample

Perfect linearity and maximum resolution throughout a measurement range that was previously unattainable are attributes of the completely new, ground-breaking NanoEye displacement system. An optoelectrical sensor that can encode and translate a position into a digital signal powers the NanoEye.

The benefit of using a linear encoder is that its linearity, accuracy, and resolution hold steady throughout the measurement and temperature range. NanoEye requires no upkeep.

NanoEye – Largest Measuring Range, Highest Resolution

Up until now, it was impossible to achieve perfect linearity and maximum resolution over the measuring range of the new, innovative opto-electrical NanoEye displacement system.

Maximum Flexibility

With two furnaces available for use, the double furnace sliding carrier offers the possibility to cover the full temperature range of –180 °C to 2000 °C. Alternatively, it can be used to increase the sample throughput.

User-Optimized Design

Maximum operational safety and ease of use are ensured by a wide force range for more delicate samples, integrated mass flow controllers, and electrical thermostatting of the measuring cell to suppress external temperature influences.

Utmost Versatility

The system’s broad dynamic range allows for the measurement of both hard and soft samples without compromising their characteristics. It also creates a bridge to thermomechanical analysis (TMA) and allows force modulation.
