OverviewThe °C Breeze Fog Instrumentation system is used for the visualization of airflow profiles, using low-impulse, thermally neutral fog. This handheld device allowsmobility in large areas or remote locations where a direct connection to power is not practical. The °C Breeze provides a steady stream of condensed fog, capable of filling 3 m 3 [100 ft 3] in constant-on mode, before evaporating. The micro-sized fog particles provide excellent air flow visibility without premature settling or dispersion. The supplied nozzle extension tube allows precise fog delivery into small spaces. This easy-to-operate unit produces fog quickly with virtually no warm-up delay. Fog may be generated continuously for 10 minutes on a single battery charge, or, using the optional 110/230V AC wall power supply, fog can be generated continuouslyfor a period of up to one hour.The °C Breeze uses a high quality, FDA Generally Recognized As Safe “GRAS”, approved chemistry for a clean, safe, non-toxic fluid. Applications include microbiological safety cabinet and chemical fume hood certification, critical containment verification for medical and clean technology, building ventilation testing, electronic system cooling design studies, and generalized flow visualization work.ValidationYour Partner for Airflow Sensing & Controls°C BreezeISO-9001 certified, world-class and manufacturer of airflow monitoring, and control we pride ourselves on solutions which provide differentiation, and service or 1.877.334.7332*****************Features•Easy-to-use, battery operated, handheld portable fogging device•Neutral density, nontoxic fog, traces airflow profiles •High opacity and long visual latency to meet your application needs•Uses FDA GRAS approved, non-depositing, oilless and smoke-free fog fluid (residence time of 30-60s)•Useful for overhead or under floor applications •Starts in seconds, no warm-up delay•Switch options include constant-on or toggle on/off fog deliveryThe °C Breeze System comes with:•°C Breeze Visualization Instrument •Locking Carrying Case with Keys •Nozzle Extension Tube, 225 mm [9”]•500 ml [17 oz] Fluid Bottle •12 VDC Lead Acid Battery •Battery Charger •User Manual•Quick Start Guide•Material Safety Data Sheet (MSDS)[upon request]•Switch option for high/low fog operation •Includes battery charger with illuminating LED charge indicator•Available NiMH battery option •International power plug adapters available•Wireless, remote control available•Dedicated power supply for continuous (battery-less) operation available •Useful in lab/cleanroom testing (ISO 14644)Remote Control Operation Dedicated Power Supply Airflow T ool Set。

tsi9545风速仪工作原理一、引言TSI 9545 风速仪是一种用于测量风速的仪器，广泛应用于气象、环境监测、能源等领域。
本文将介绍 TSI 9545 风速仪的工作原理。
二、基本原理TSI 9545 风速仪采用了热线式风速传感器，其基本原理是利用热线受风冷却的特性来测量风速。
当空气流过热线时，由于空气的流动会带走热线上的热量，导致热线温度下降。
通过测量热线温度变化，可以计算出空气的流速。
三、详细原理1. 热线传感器热线传感器是 TSI 9545 风速仪中最核心的部件之一。
它由两个金属丝组成，一个作为加热丝，一个作为测量丝。
加热丝通电后发生加热，并使周围空气温度升高；而测量丝则处于静止状态。
当空气流过时，由于空气具有较好的导热性，在流经测量丝时会带走一定的热量，导致测量丝温度下降。
通过测量测量丝温度变化，可以得到空气的流速。
2. 电路TSI 9545 风速仪的电路主要包括恒流源、放大器、滤波器、模数转换器等部分。
其中，恒流源用于提供一定的电流给热线传感器加热丝；放大器用于放大测量丝的信号；滤波器用于去除杂散信号和噪声；模数转换器则将模拟信号转换为数字信号输出。
3. 算法根据热线传感器的原理，可以得到以下公式：Q = k * (T1 - T2)其中，Q 表示空气流过热线带走的热量，k 表示比例常数，T1 和 T2分别表示加热丝和测量丝的温度。
通过对公式进行变形，可以得到以下计算公式：v = (Q / k) / A其中，v 表示空气流速，A 表示传感器截面积。
通过对公式进行进一步简化和优化，可以得到 TSI 9545 风速仪所采用的算法。
四、总结本文介绍了 TSI 9545 风速仪的工作原理。
通过对热线传感器、电路和算法等方面进行详细的分析，可以更好地理解 TSI 9545 风速仪的工作原理和测量原理。
