Supported Applications
The Dwyer Series BTPM Panel Mount Bimetal Thermometers are designed to easily mount in most instrument panels. The product overview identifies these thermometers as ideal for HVAC, automotive, and food industry applications, chemical operations, and more.
Operating Conditions & Performance
The series measures temperature with an accuracy of ±1% and a resolution of less than 2% of scale. Ambient operating temperatures range from -40 to 392°F (-40 to 200°C). The available measurement ranges are -40 to 160°F and 0 to 200°F.
Key performance specifications include:
- Dial Size: 2-1/2"
- Lens: Glass (scratch resistant)
- Housing Material: Series 300 SS
- Wetted Materials: 304 SS
- Process Connection: 1/4" NPT
- Weight: 9.2 oz (260 g)
Configuration Options
The Series BTPM offers configurable stem lengths and scale options to accommodate specific installation needs.
- Stem Lengths: 4", 6", or 9"
- Dual Scale Option: Available by changing the last digit of the model number to "D" (e.g., BTPM24041 becomes BTPM2404D).
- Mounting: The front flange features three 5/32" diameter holes for quick attachment to instrument panels.
The probe dimensions include a stem diameter of 0.25 [6.35] (derived from diagram callout "01/4 [06.35]"). The front flange measures 3-21/64" [84.53] in diameter with a thickness of 21/32" [16.67].
Key Product Differences
Variants within the series are distinguished by their temperature range and stem length, as defined in the model selection table.
- BTPM240xx: 4" stem length; available with -40 to 160°F or 0 to 200°F ranges.
- BTPM260xx: 6" stem length; available with -40 to 160°F or 0 to 200°F ranges.
- BTPM290xx: 9" stem length; available with -40 to 160°F or 0 to 200°F ranges.
The model number guide follows the format BTPM<TEMP RANGE CODE><STEM LENGTH CODE><DUAL SCALE OPTION>. Models ending in "1" represent single-scale configurations, while models ending in "D" indicate dual scales are available by changing the last digit.
