Supported Applications
The Dwyer Series STC Pipe-Mount Bimetal Surface Thermometers are designed to accurately measure the surface temperature of pipe sizes ranging from 3/4" to 2-3/8". These instruments feature a bimetal spiral spring sensing element that provides quick temperature readings, making them suitable for temporary installations and applications requiring non-intrusive temperature measurements.
Operating Conditions & Performance
The Series STC operates within an ambient temperature range of 14 to 302°F (-10 to 150°C). The instruments provide a measurement accuracy of ±2% with a resolution of less than 4% of scale. Available measurement ranges include -50 to 250°F, 0 to 150°F, 70 to 370°F, and 70 to 500°F in Fahrenheit; corresponding Celsius ranges are -40 to 120°C, 20 to 180°C, and 20 to 260°C. The dial size is 2" [50.8] with a depth of 1" [25.4].
Key Specifications
- Housing Material: Steel
- Lens: Glass
- Mounting Type: Clip-on Mount
- Weight: 3.4 oz (95 g)
Configuration Options
The series is configured by selecting a specific model number that corresponds to the required temperature range and pipe size. The Series STC supports three distinct clip sizes to accommodate different diameters:
- 3/4" to 7/8": Clip dimension A of 1-5/8 [41.28]
- 1" to 1-5/8": Clip dimension A of 1-7/8 [47.63]
- 1-5/8" to 2-3/8": Clip dimension A of 2-1/2 [63.5]
Model numbers follow the pattern STC - - - , with specific variants such as STC141, STC151, and STC172 covering various combinations of ranges from 0 to 150°F up to 70 to 500°F.
Key Product Differences
Variants within the Series STC are distinguished by their specific temperature range and compatible pipe diameter. Models ending in '1' typically denote Fahrenheit ranges, while models ending in '2' indicate Celsius ranges (e.g., STC151 for -50 to 250°F versus STC152 for -40 to 120°C). The first digit of the model number indicates the pipe size category: '1' series covers 3/4" to 7/8", '3' series covers 1" to 1-5/8", and '4' series covers 1-5/8" to 2-3/8". All variants share the same steel housing, glass lens, and clip-on mounting mechanism.
