Omega TVS-1112 Velocity and Temperature Measurement System

The TVS-1004 and TVS-1008 automatic temperature and velocity scanners are portable, 4- and 8-channel hot wire anemometer systems. The TVS-1100 series are factory expandable for up to 32 total sensors. Fully automated, these research-quality instruments take accurate single- or multi-point measurements of air temperature, velocity and surface temperature in complex environments, such as PCBs and electronics enclosures. When used as temperature loggers, they can measure both fluid and solid temperatures.

The TVS-1000 series employ patented, fast response, omnidirectional sensors, which measure both temperature and velocity. This patented single-sensor technology eliminates errors introduced as a result of air flow being non-isothermal. Each precisely calibrated sensor is flexible and robust with a low-profile configuration that allows minimally intrusive mounting throughout the peaks and valleys created by the PCB components. These systems require a PC to operate and utilize the provided software for data acquisition and reporting.

The candlestick style sensor, is a flexible, robust, base-and-stem design sensor that measures both temperature and air velocity for characterizing thermal conditions in electronic systems. The candlestick sensor is narrow and low profile to minimize the disturbance of the heat flow in the test domain. It features a flexible, plastic-sleeved stem, which facilitates installation and repositioning during the testing process. Sensors are calibrated for low (natural convection) and high velocity flows. They are capable of temperature measurements ranging from -30 to 150°C ±1°C. Velocity measurements range from 0 to 20 m/s (4,000 ft/min). Higher ranges available, contact Omega for details. The use of a single sensor to measure both temperature and velocity eliminates errors that can occur when airflow is non-isothermal. Multiple candlestick sensors can be easily installed to thoroughly map a system’s thermal and airflow conditions. Their robust nature allows for continuous repositioning and reading.
