Vaisala HUMICAP Humidity and Temperature Transmitter Series HMT330 has been upgraded with LAN and WLAN communication options and a display alarm.
With the new Ethernet communication options you can connect the transmitter into a computer network providing a virtual terminal connection between the transmitter and a PC. Communication is then possible using for example Telnet software.
Each transmitter is given an IP address, making it a uniquely addressed device in the network.
The LAN and WLAN options make it easy to add a new humidity transmitter to an existing Ethernet network. Also, applications that do not allow holes through walls and ceilings, or the installation of new cables, benefit from this solution.
A new display alarm function is now a standard feature in Vaisala humidity transmitters equipped with a built-in display.
With this function the user can set alarm trigger limits for two distinct measured quantities.
When the trigger limits are exceeded, a real-time alarm appears on the display.
The Series HMT330 consists of six models: HMT331 for wall mounting; HMT333 for duct mounting and tight spaces; HMT334 for high pressures up to 100bar and vacuum conditions; HMT335 for high temperatures; HMT337 for high humidity and meteorological applications; HMT338 for pressurised pipelines up to 40bar.
Fteatures include: warmed probe for superior performance in condensing environments; shows measurement trends and one-year history graphically; corrosion resistant IP65 housing; NIST traceable (certificate included); integrated data logging, with more than four years of measured history.
