Humidity Transmitter HMT330 from Vaisala features integrated data logging
Story
Vaisala HUMICAP® Humidity and Temperature Transmitter Series HMT330 now offers several new features including a data logging option, Chinese as a new user interface language, the new generation Vaisala HUMICAP® 180 R sensor and a USB connection cable for computers. In addition, the HMT330 has a new display with a white background light for easier reading.
The new data logging option is a module that is slotted into the transmitter. The module has an enhanced memory that can store data of three measured parameters. When logging is fixed at 10 second intervals, data can be stored for as long as 4 years and 5 months. A real-time clock with a battery backup ensures accurate date and time stamps even when no power is supplied to the transmitter. The logging feature does not require any pre-setting; data is ready and available when needed. The stored data can be viewed graphically on the display throughout the logging period, and the user can zoom in and out as necessary. Any period of measured results can be downloaded via a serial interface to a computer.
Vaisala also introduces the new generation of its proven Vaisala HUMICAP® Relative Humidity Sensor, the HUMICAP®180R. This new sensor provides further improved long-term stability and chemical tolerance as well as resistance against various contaminants.
To connect the service port of the HMT330 transmitter to the USB port of a computer, Vaisala now offers a USB-RJ45 Serial Connection Cable. It operates as an RS232 – USB converter at a data transfer rate of 19200 bauds/s.
In addition to the eight existing languages, the graphical display interface now also includes Chinese. Users can select the language on the display menu. With the new white background in the display, contrast is increased and readability is improved.
