Supported Applications
The Dwyer Series S2-2 General Purpose Surface Temperature Assembly is designed for monitoring the temperature of indoor distribution lines when it is not possible to penetrate the pipe. The assembly features a strap-on connection that quickly wraps around pipes and can be securely tightened using a flat head screw driver.
Operating Conditions & Performance
The series operates within a process temperature range of -32 to 240°F (-35.5 to 115.5°C). Accuracy specifications vary by sensor type as documented:
- Nickel RTD: ±0.5°F @ 32°F (0°C)
- Balco RTD: ±0.1% @ 32°F (0°C)
- Platinum RTD: ±0.6% @ 32°F (0°C)
- Thermistors: ±0.36°F from 32 to 158°F (0 to 70°C)
The housing is constructed of plastic in the shape of a standard junction box with overall dimensions of 4-1/16 [103.21] height and 2-1/4 [57.15] width.
Configuration Options
The Series S2-2 is available in a configuration that fits pipe sizes from 2 to 5 inches via the strap-on process connection. Electrical access is provided through multiple conduit holes: three 0.896" [22.76 mm] 1/2" NPT and two 0.743" [18.87 mm] 3/8" NPT knockouts.
The series supports a choice of 11 output options to communicate with standard building control systems, though specific signal types are not enumerated in the source documentation. Sensor element selection includes:
- Ni 1000 Ω RTD (Model S2-23)
- Balco 1000 Ω RTD (Model S2-24)
- 5K Ω Thermistor (Model S2-27)
- 100K Ω Thermistor (Model S2-28)
- 2252 Ω Thermistor (Model S2-2A)
The model number guide follows the pattern S2-<XX>, with examples including S2-23, S2-24, S2-27, S2-28, and S2-2A.
Key Product Differences
Variants within the series are distinguished by their sensor type. The documented model table lists specific pairings of part numbers to sensors: Ni 1000 Ω RTD for S2-23, Balco 1000 Ω RTD for S2-24, and various thermistor resistances (5K Ω, 100K Ω, 2252 Ω) for models S2-27, S2-28, and S2-2A respectively. The series encompasses ten enabled variants ranging from part number S2-21 through S2-2B.
