Specification


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.
