Product overview
Separate probe and wireless unit
Threaded temperature probe connected by cable to a grey housing with mounting ears and an upright antenna.
The Pt100 or thermocouple probe is separate from the wall-mounted radio enclosure. A cable joins the sensing assembly and wireless unit, leaving the temperature probe and radio housing as distinct parts of the instrument.
Configuration and selection
Temperature-probe end reference
Another temperature-probe form has a short closed rod below a threaded fitting and hexagonal shoulder.
Model references: HPT-21T and HPT-21T0. Sensing configurations use Pt100 or thermocouples, with 304 or 316L stainless-steel contact-material options.
| Reference span | −100–400 °C |
