MDLT-ONE

MDLT-ONE - Micro Dilution Tunnel

부분 희석 PM 샘플 장치

부분적 희석법을 사용하여 미립자 배출물을 샘플링하도록 설계된 분석기입니다. 전체 배기 중 소량을 희석하여 미립자(PM) 필터를 통해 일정한 유량 생성이 가능합니다. 최신 규정에 맞추어 탄생한 소형 제품으로 고정밀 벤츄리 유량계와 파에조 작동 밸브를 사용하여 보다 빠른 반응이 가능합니다.

Segment: Automotive
Manufacturing Company: HORIBA, Ltd.

Small footprint

Heated filter system and flow controllers installed in a single rack. Swivel connection of tunnel section to cabinet allows flexible installation.

Flow weighting (EPA-approved technology)

Allows user to collect PM on a single filter over all three phases of FTP by adjusting sampling flow rate over the filter to weight the filter face velocity over the three phase of the FTP based on weighting targets. This EPA-approved technology increases the measurement accuracy for meeting the upcoming CARB LEV III 1`mg/mile emission limit and reduces filter weighing cycles from three to one, eliminating manual checks and calculations.

Automatic filter changer

Increases testing efficiency, allowing a maximum of 28 tests to be run without manual intervention. This feature can be mounted in the main rack to keep equipment footprint small.

Automatic calibration software enhances accuracy and ease of use

The MDLT-ONE series performs automatic calibration by flowing air in-series through two venturi flow meters and correcting any difference to zero in the software. This can be included in an automated sequence within a test template.

Integrated Operating Platform

HORIBA ONE series systems employ a common use interface, “HORIBA ONE PLATFORM” offering future expandability and ease of integration into test automation systems.

*1, For the filter face velocity in the regulations (less than 100 cm/s), the flow rate for the φ47 mm filter must be 65 standard L/min.
*2, Input the amount of PM collected on filter to calculate PM mass. It is necessary to input engine output (kW) to calculate the PM mass engine output (g/kWh).
*3, Please contact HORIBA, when you order.
