outdoor humidity and temperature transmitters OHT

Outdoor Humidity & Temperature Transmitter OHT without Display.



Description

The OHT is an outdoor humidity and temperature transmitter measures the humidity and temperature of air.

The outdoor humidity and temperature transmitter OHT 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 etc as option

The OHT outdoor humidity and temperature transmitter can be supplied with or without display.

The built-in display on outdoor humidity and temperature transmitter OHT show actual humidity and actual temperature.


E-paper Display

The display show the actual value of each parameter
Humidity (rH) + Temperature (T).

The display versions for OHT outdoor 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.
