Supported Applications
The Dwyer Series DBT Digital Solar-Powered Bimetal Thermometer is designed for temperature measurement in environments with adequate light. Documented applications include boiler or chiller temperature monitoring and HVAC duct monitoring.
Operating Conditions & Performance
The series operates on a 3-volt solar cell requiring a minimum of 35 LUX to function. Measurement ranges are available as -58 to 302°F (-50 to 150°C) or -58 to 158°F (-50 to 70°C). Accuracy is specified as ±1% FS within the range of 32 to 122°F (0 to 50°C); accuracy outside this specific band is not defined in the source data. The unit features a response time of 15 s and provides resolution to 0.1°. Wetted materials consist of 304 SS, while the housing material is listed as 300 SS.
Configuration Options
The Series DBT offers configurable stem lengths and measurement ranges across its model lineup. Key specifications include:
- Display: 3-1/2 digit LCD with a 3" dial size.
- Lens Material: Glass (per data sheet) or Acrylic (per manual).
- Process Connection: 1/2" NPT-adjustable angle, allowing mounting in virtually any position.
- Stem Dimensions: Diameter of ø1/4 [ø6.35] with stem lengths ranging from 2.5" to 24" based on model selection.
- Field Selection: Engineering units can be selected in the field (°F or °C) by removing the back cover and adjusting a switch.
The series supports stem lengths of 2.5", 4", 6", 9", 12", 15", 18", and 24" paired with either temperature range option, resulting in distinct model numbers such as DBTA3251 or DBTA3242.
Key Product Differences
Variants within the Series DBT are distinguished by stem length and measurement range. Models ending in "1" (e.g., DBTA3251) correspond to the -58 to 302°F (-50 to 150°C) range, while models ending in "2" (e.g., DBTA3252) correspond to the -58 to 158°F (-50 to 70°C) range. The stem length is encoded within the model number; for example, a "40" segment indicates a 4" stem and a "90" segment indicates a 9" stem.
