HMT370EX transmitters can be used with 6 dierent probe options that are designed for a
variety of applications. The installation options vary from wall mounting (fixed HMP371 probe
option) to, for example, duct installations (as shown in the HMP373 example in Figure 33
(page 83)) and ball valve installations (HMP378 probe option for pressurized pipelines).
The dierent probe options have varying operating environment specifications, installation
methods, and installation accessories depending on their intended applications. For more
information on each option, see HMT370EX probe options overview (page 61). Also review the
safety information related to allowed ambient temperature ranges for probes before
installation: see the information relevant to your certification region in Regional safety
certification overview (page 19).
