1. Wind Tunnel (풍동)

   풍동은 유체 실험에서는 기초 장비이며, 금세기 Software 의 발전으로 전산유체(CFD)를 이용해서

    실험을 대신하는 경향이 있었으나 그것또한 실험으로 얻어진 Data를 이용해야 하는 이유로

    풍동은 기계, 항공, 우주, 조선, 건축, 토목등 유체에 관련된기초 실험에 꼭 필요한 장비로 인식되어

    지고 있습니다.  

   

    풍동은 사용목적, 풍속의 크기, 시험부의 크기, 설치장소 및 조건, 계측기기류 들을 고려하여 선택해

    야  합니다.

 11. Hot Wire Probe/Pitot Tube/Anemometer Calibrator(풍속 교정기)

 

 CAL-2000
DIGITAL AIR SPEED CALIBRATOR


Introduction

The CAL-2000 is a high-precision digital air-speed calibration system designed especially for calibration of Hot-Wire and Hot-Film sensors. Its powerful motor generates Air velocity of 1 to 70 m/sec over varying Temperature, Humidity and Barometric pressure conditions. A high-speed microprocessor monitors all parameters continuously, and maintains a constant air velocity or a sweep between velocities at a known rate, according to user's request via RS-232. The user may also send a requested motor velocity or read each one of the four built-in environmental sensors in engineering units.

The CAL-2000 unit features a uniform flow rate, with low turbulence level. Its large output cross-section (1.95 sq. Inches) allows calibration of almost any standard sensor. The probe angles can be adjusted easily by two manual controls.

The CAL-2000 is a complete stand-alone system. It does not require any pressure inlets or external sources for generating the requested air speed. Its "Micronel" filter provides clean air flow without any dust or moisture particles which might attach to the sensor and change its calibration curve. The flow range configuration is done by entering a plate to a slot inside the noise filter section.


Features

Stand-Alone System.
Turnkey System.
RS-232 Serial Interface.
High Accuracy to 0.5% of Reading.
Velocity Controller maintains highly stable Air Speed Velocity.
Environmental monitoring:
- Barometric pressure,
- Humidity,
- Differential pressure,
- Temperature.
Calibration curve (with LDA) Supplied with each system.

Applications

Calibration of hot-wire and hot-film sensors.
In-situ calibration.

Software

The CAL-2000 system is supplied with a setup and control software for PC compatible computers. All system setups can be controlled remotely via that software. The system also interfaces with "LIN-FLOW" software for calibration of Hot-Wire sensors with the AN-2000 software. The system may also be operated from any computer (PC, Vax, Macintosh, Sun etc.) which contains a serial port (RS-232C standard), by sending simple ASCII commands.


Specifications

Flow Rate: 1 to 70 m/sec.
Accuracy: 0.5% of reading.
Temperature range: 0 to 50 deg. C.
Humidity: 0 - 90% RH
Power Requirement: 230 Vac +/- 10% (115V models available).
Power consumption: 650W at full speed.
Weight:69.5 Kg.
