HMT370EX transmitters can be used with 6 different 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 1) and ball valve installations (HMP378 probe option for pressurized pipelines).
The different 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. 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.
