Figure 27 Cleaning of Tightening Cone

The following numbers refer to Figure 27:

1 = Fitting screw

2 = Sealing washer

3 = Tightening cone

4 = Clean cotton stick

CAUTION

In pressurized processes it is essential to tighten the supporting nuts and

screws very carefully to prevent loosening of the probe by the action of

pressure.

NOTE

When installed in a process with a 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

command PRES and XPRES on page 96) or by using display/keypad.

HMT335 for High Temperatures

HMT335 is installed similarly than the HMT333 probe but without the

supporting bar. Refer to Appendix A on page 163 for more information

on the duct installation kit for HMT335.

To avoid incorrect humidity readings, the tem

perature differences

between inside and outside of the duct must not be remarkable.
