Testo Inc.: Pressure Transmitters
September 19, 2011
The 63 Series of transmitters has expanded, and provides accuracy, long up-time, and stability regardless of the environment or project budget, according to the manufacturer. The 6321 differential pressure transmitter is a cost-effective solution for automated air conditioning and ventilation applications commonly found in commercial and institutional buildings. The midrange 6351 transmitter provides low pressure ranges down to 0.2 inches (50 Pa) and features an auto-zero function, and a variety of analog, Ethernet, and relay outputs. The 6381 and 6383 differential pressure transmitters offer optional humidity and temperature measurement. These three-in-one devices save money in initial hardware and installation costs and the auto-zero dew point sensor and patented long-term stable rh temperature sensor reduce operational costs by diminishing calibration cycles and increasing process up-time.
