Maxwellian Inc. is a Montreal based company that innovates the first optical fiber humidity probe to measure humidity and dew point in any fields with high resolution in real-time manner. Their humidity probe is optical fiber based and uses light to measure moisture and humidity, even in harsh environments. The sensor is highly accurate while being calibration and drift free in any environment with a long lifetime of up to ten years. This customizable optical sensing technology thus provides high performance at low maintenance and low production costs. Maxwellian Inc. proprietary technology has already been validated with prototypes that are composed of three main parts: (i) the sensor package that includes the optical fiber, a thermoelectric cooler (TEC), electrical connectors and the metallic enclosure; (ii) the interrogator box with the electronic boards and circuits to control the sensor and extract measurements data; (iii) the electrical/optical connections between the interrogator box and the sensor package. Maxwellian prototype outperforms the electrical and bulk optics technologies competition in terms of cost efficiency as well as speed and precision [GE], [Kahn], [Mich]. The form factor and dimensions of the sensor is similar or smaller than competitors products, however it would greatly benefit from a miniaturized package with the electronic that would be brought closer to the sensor or be part of the packaged system as in Internet of Things (IoT) type sensors. As a first step towards sensor miniaturization, Université de Sherbrooke (UdeS) and Maxwellian Inc. will collaborate in this research project to reach two main objectives. Firstly, they will design and fabricate a mechanical miniaturized sensor package with a commercial or micro-fabricated Peltier and the optical fiber for lab testing. Secondly, they will evaluate feasibility of a sensor package that complies with hygrometer specifications in harsh environment standard Cass1/Division 2 through mechanical and thermal design and simulation. The interrogator box and electrical optical connections are kept as is. They may be part of a following project to enhance miniaturization.

Maxwellian Inc.是一家位于蒙特利尔的公司，它创新了第一个光纤湿度探测器，以实时以高分辨率的任何领域来测量湿度和露点。它们的湿度探针是基于光纤的，即使在Harmsh环境中，也使用光来测量水分和湿度。传感器在校准的同时非常准确，在任何环境中，长期长达十年。因此，这种可自定义的光学感官技术可在低维护和低生产成本下提供高性能。 Maxwellian Inc.专有技术已经用由三个主要部分组成的原型验证：（i）传感器封装，其中包括光纤，热电冷却器（TEC），电气连接器和金属封面； （ii）带有电子板和电路的审讯盒，以控制传感器并提取测量数据； （iii）审讯框和传感器包之间的电气/光学连接。 Maxwellian原型在成本效率以及速度和精度[GE]，[Kahn]，[Mich]方面优于电气和批量光学技术竞争。传感器的外形和尺寸与竞争对手产品相似或小，但是，它将通过电子化包装带来的电子封装将受益匪浅，该电子套件将带来更靠近传感器或成为包装系统的一部分，就像物联网（IoT）类型传感器一样。作为传感器小型化的第一步，Sherbrooke大学（UDES）和Maxwellian Inc.将在该研究项目中合作，达到两个主要目标。首先，他们将使用商业或微型制造的Peltier设计和制造机械小型传感器包装，以及用于实验室测试的光纤。其次，他们将通过机械和热设计和仿真来评估符合Harmsh环境标准CASS1/DIVEMAULTY在HARMSH环境标准CASS1/DIVEMAUTION中的湿度计规格的传感器套件的可行性。询问器框和电气连接保持原样。它们可能是以下项目的一部分，以增强小型化。
