DMT345 & DMP346 DRYCAP® Dewpoint Transmitters Constructed for humidity measurement in industrial drying applications with particularly high temperatures. As the probes are designed to be positioned directly in hot processes, there is no need for sampling systems and trace heating. Optional data logging and (W)LAN interface. The DMT345 measures humidity in temperatures up to 180°C (+356 °F) The DMT346 measures humidity in temperatures up to 350 °C (+662 °F) Unique auto-calibration Vaisala DRYCAP® Sensor provides accurate, reliable measurement with excellent long-term stability and fast response Withstands condensation Optional local display with keypad, mains power supply module and alarm relays User-programmable, versatile and easy to use Integrated data logging, with over four years of measured history LAN and WLAN communication options DMT345 / DMT346 Brochure DMT345 Order Guide DMT346 Order Guide DMT345 /DMT346 User Guide Dewpoint measurement Range Accuracy Sensor DMT345 -40..+100 °C (-40..+212 °F) ±2 °C (±3.6 °F) Vaisala DRYCAP® 180S DMT346 -25..+100 °C (-13..+212 °F) ±2 °C (±3.6 °F) Vaisala DRYCAP® 180S Temperature measurement DMT345 Range    with sensor warming Accuracy Temperature sensor 0...+180 °C (+32...+356 °F) upper range limited by humidity ±0,4 °C at +100 °C (±32.72 at 212 °F) Pt 100 IEC 751 1/3 class B Operating environment Mechanical durability of       probes       transmitter body       with display DMT345 up to +180 °C (+356 °F) -40..+60 °C (-40..+140 °F) 0..+60 °C (32..+140 °F) DMT346 up to +350 °C (+662 °F) -40..+60 °C (-40..+140 °F 0..+60 °C (32..+140 °F) Inputs and outputs, both models Operating voltage Power consumption @ 20 °C (Uin24 VDC)   Uout 2x0...1V/0...5V/0...10V   Iout 2x0...20mA   RS-232   display and backlight   during sensor purge Analog outputs Digital outputs Ethernet interface (optional)      Supported standards      Connector      Protocols WLAN interface (optional)      Supported standards      Antenna connector type      Protocols      Security Authentication / Encryption      Open / no encryption      Open / WEP      WPA Pre shared key / TKIP      WPA Pre shared key / CCMP (a.k.a.
