Thermal Instrumentation for Measurement & Evaluation

• Non-intrusive, small sensors which are interchangeable - simply unplug & plug in another one - no field calibration necessary!!
• Real-time data
• Simultaneous, multi-point measurements, each unit accepts up to 24 sensors
• Multiple COM ports can link up to 4 ATMs or TCMs
• User-defined sampling times from 1-99,999 seconds
• Displays in metric or Imperial units
• Interfaces to serial port (RS232) on a PC
• Universal external power supply (90-265 VAC, 47-63 Hz) included

Multipoint measurement of airflow velocity as well as air and surface temperature analysis are crucial steps in the new product development process. These procedures, however have traditionally been inexact, labor-intensive, repetitive and tedious. T.I.M.E. has been designed to reduce cost, increase efficiency, improve accuracy and compress testing and validation time.

Now, you can develop a complete thermal and airflow map of your product or system by obtaining simultaneous airflow and temperature as well as surface temperature measurements. The complete T.I.M.E. system consists of two multi-channel instruments - the ATM-24, an airflow and air temperature monitor using the interchangeable AccuSense CAFS sensors, and a thermocouple monitor, the TCM-24. Up to four multi-channel instruments can be linked to obtain real-time, multi-point measurements, while the AccuTrac software (for Windows 95, 98, and NT) allows you to display, save, review, graph and print the acquired data, without ever having to export the data to another program. 192 sensors (CAFS or thermocouples) can be used simultaneously.

The ATM-24 eliminates the tedious, time-consuming and costly task of manual data recording using a hot-wire anemometer. Designs can be analyzed and modified quickly based on accurate, real-time data. The ATM-24 is a powerful tool in verifying computational fluid dynamics software results. Measurements from locations that are physically difficult to access are possible with the CAFS sensors. The ATM-24 gathers the information from the CAFS sensors and transmits it to a computer via an RS-232 connection for on-line analysis.

The CAFS Series of Plug-In Probes is specially designed for use with the ATM-24. Its patented technology offers complete interchangeability between sensors. For instance, you may use several different calibrations and cable lengths at the same time and change the mix for a later test with NO FIELD CALIBRATION. Simply plug in a sensor and begin taking readings! A variety of calibrations are available from 0.15 to 22.5 m/s (30-4500 fpm).

• Measure four points simultaneously
• Ability to store thousands of individual readings
• All data is stored in the Quattro even if it is turned off
• Data can be printed or downloaded to a PC
• Interchangeable sensors allow for easy field maintenance
• Data can be reviewed quickly & easily
• Internal pressure sensor automatically compensates for altitude

The Cambridge AccuSense Quattro Flow Velocity Analyzer is a mobile unit designed for accurate, cost-effective multipoint evaluation. Portable and self-contained, the Quattro Flow is powered by an internal rechargeable battery that allows for 6-8 hours of continuous use. The full package consists of a lightweight measurement instrument with four sensor ports, a choice of low-profile or clip-on ruggedized AFS airflow sensors and an optional printer.

Air velocity and air temperature data collected by the Quattro can be displayed, saved, reviewed, graphed and printed without having to export the information to another program. The internal record program allows for the creation and accumulation of several grids for testing fume hoods, biosafety cabinets, HEPA filters and ducts; with each record representing a grid. Each individual sensor reading is stored in rows and columns specified by the user. Not only is each individual sensor reading stored, but the average flow and volumetric flow are automatically calculated. Records can be printed, stored, modified and downloaded at any time.
