Chapter 3 _______________________________________________________________ Installation
VAISALA _______________________________________________________________________ 43
See Appendix A on page 171 for a presentation of the following probe
installation kits for PTU307 with installation examples:
- Duct mounting kit
- Cable gland
- Pressure tight Swagelok connector
- Vaisala's 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 PTU307 (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 PTU307 probe. Make sure that heat
does not transfer from the warmed probe to the temperature probe.
