CHAPTER 2
PRODUCT OVERVIEW
This chapter introduces the features, advantages, and the product
nomenclature of the Vaisala Combined Pressure, Humidity, and
Temperature Transmitter PTU300.
Introduction to PTU300
The PTU300 transmitter provides reliable pressure measurement in a
wide range of applications. Analog outputs can be chosen between
current and voltage signals. Alternatively, digital outputs RS-232
(standard) or RS-422/485 (optional) can be selected. A local display is
also available. The quantities measured and calculated by PTU300 are
presented in Table 4 on page 21. The quantities available as an option are
presented in Table 5 on page 21.
The PTU300 transmitter combines three measurement parameters:
pressure, temperature and humidity. The applications of the PTU300
range from calibration laboratory environmental condition monitoring to
laser interferometer active wavelength compensation and GPS
meterorological measurements.
The PTU300 transmitter is available with one or two pressure
transducers. The PTU301, PTU303 and PTU307 probes are available for
the PTU300 transmitter.
In outdoor applications it is recommended to use the HMT330MIK
mounting kit with the PTU300 transmitters.
