907023/337 for High Humidity
Applications
The 907023/337 is for environment where relative humidity is very
high, near saturation. The warmed probe prevents the saturation of the
sensor. An additional temperature probe is also available.
See Appendix A on page 163 for a presentation of the following probe
installation kits for 907023/337 with installation examples:
- Duct mounting kit
- Cable gland
- Pressure tight Swagelok connector
- Meteorological Installation kit
The installation kits are available for both humidity and temperature
probe.
Temperature Probe (Optional)
An additional temperature probe is available to measure the ambient
temperature when the 907023/337B (with probe warming) is used.
The additional temperature probe allows you to measure other
humidity quantities apart from dewpoint and mixing ratio. The
temperature probe must be connected to the transmitter at the factory.
Do not cut and re-connect the cable yourself.
You must install the additional temperature probe in the same
measurement environment as the 907023/337B probe. Make sure that
heat does not transfer from the warmed probe to the temperature
probe. For an example installation, refer to section Example of
Installation Through Roof on page 169.
907023/338 for Pressurized Pipelines
Due to the sliding fit the 907023/338 is easy to install into and remove
from the pressurized process. The probe is especially suitable for the
measurements in pipelines. See section Ball Valve Installation Kit for
907023/338 on page 170.
