HUMIDITY - DE LUXE

HTW Wall Mount RH& T Sensor

Description
The new HTW range of humidity and temperature sensors offer the latest technology high precision and accuracy RH&T element, and installed in our new revised robust series housing.

The housing has an added benefit of being easy to install with the new hinged lid, which can also be screwed closed to make the unit tamperproof.

An optional multi-line backlit LCD display is available, along with a direct PTC/NTC sensing element (when this option is required, the type of element must be specified at the time of ordering).

Output signals of 0-10Vdc, 0-5Vdc or 4-20mA (loop or externally powered) for all measured values and RH are available as standard.

A custom output range for temperature can be requested, between –20 and +50°C (–4 to +122°F).

HTW

Wall Sensor for relative/absolute humidity, mixture ratio, dewpoint and enthalpy

The universal humidity sensors are used to determine diverse characteristic variables in humidity measurement.

The instrument measures relative humidity and the temperature of the ambient air. From these measurments, the different characteristic variables are internally calculated.

There are two versions

• 010 with two outputs of 0…10 V.

• 420 with two outputs of 4 … 20 mA.

Output variables for the outputs can be defined via DIP switches.

• relative humidity [% r.H.]

• absolute humidity [g⁄m³]

• mixture ratio [g⁄kg]

• dew point temperature [°C] or enthalpy

• [kJ⁄kg] (while neglecting the atmospheric air pressure) are alternatives selectable for output 1.

At output 2, four different measuring ranges for ambient temperature [°C] can be selected.

Ex-factory condition (default) for output 1 is relative humidity 0 ...100 % r.H., for output 2 temperature measuring range 0 ... 50 °C.

Because of the different configuration alternatives provided, numerous measurement and control tasks can be solved by means of just one device. These devices are to be operated in pollutant-free non-precipitating air, with neither above-atmospheric nor below-atmospheric pressure at the sensors.

Applications

• medical technology

• refrigeration
