NOTE When HMT314 is installed in a process with pressure differing from
normal atmospheric pressure, please enter the pressure value of the
process (in hPa or mbar) into the transmitter memory via the serial line
(see PRES Set Ambient Pressure for Calculations on page 48).
HMT315 for High Temperatures
HMT315 is installed similarly than the HMT313 probe but without the
supporting bar. Refer to Appendix A on page 81 for more information on
the duct installation kit for HMT315.
To avoid incorrect humidity readings, the temperature differences
between inside and outside of the duct must not be remarkable.
HMT317 for Demanding Processes
The HMT317 is for environment where relative humidity is very high,
near saturation. The warmed probe prevents the saturation of the sensor.
See Appendix A on page 81 for a presentation of the following probe
installation kits for HMT317 with installation examples:
- Duct mounting kit
- Cable gland
- Pressure tight Swagelok connector
