Duct Humidity and Temperature Transmitters, DHT-series

duct humidity and temperature transmitters with display DHT

Duct Humidity & Temperature Transmitter DHT with Display.


Duct Humidity & Temperature Transmitter DHT without Display.



Description

The duct humidity and temperature transmitter DHT measures the humidity and temperature of air.

The duct humidity and temperature transmitter DHT converts the measurements humidity and temperature into standard signals of 0-10 Vdc or 4-20 mA.

Passive temperature sensor PT1000, PT100, NTC 10K, NTC 20K, NTC 1.8K, NI1000 as option

The DHT duct humidity and temperature transmitter can be ordered with or without display.

DIP switch on pcb to select relative humidity, absolute humidity, dew point or enthalpy measurement.

The built-in display on room humidity and temperature transmitter DHT show actual humidity and actual temperature.

Probe lenght for duct humidity and temperature transmitter DHT is 220 mm.

Mounting flange is included in the scope of delivery for DHT duct humidity and temperature transmitter.


E-paper Display

The display versions for DHT duct humidity and temperature transmitter is an E-Paper display that reflect light just as regular paper, therefore the display is a passive (non-luminating) display.

Thin, light, flexible, good contrast, low energy consumption and no light reflections.

Easy reading even with high insolation and ambient brightness.

E-Paper displays only need energy when the display contents change.

Optics and readability are significantly better than with monochrome LCD´s or other bi-stable systems.

High readability independent of the reader's perspective.
