Fluke Probe Thermocouple Beaded K-Type
The 80PK-1 is a type K bead thermocouple designed for general purpose temperature measuring applications. It has an extremely fast response time, due to the low thermal mass of the exposed tip. The 40 in. (1 m) Teflon cable is terminated with a type K miniature thermocouple connector with 0.312 in. (0.792 mm) pin spacing. The 80PK-1 can be used with any temperature measuring instrument that is designed to accept type K thermocouples and that has a miniature connector input. The 80PK-1 must be used in Teflon-compatible environments and is not suitable for liquid immersion. Above 260°C (500°F), Teflon will emit toxic fumes.
Maximum Voltage: 24 V ac rms or 60 V dc maximum for proper safe operation
Type-K thermocouple for general purpose applications
Measurement range: -40 to 260°C
Accuracy (with respect to NBS tables for Special Grade): ±1.1°C (2.0°F) over the range of 0°C to 260°C (32°F to 500°F) typically within 1.1°C (2.0°F) of NBS Tables over the range of -40°C to 0°C (-40°F to 32°F)
Output: @ 25 °C (77 °F) = 1.00 mV (reference junction @ 0 °C)
Seebeck coefficient: 25 °C (77 °F) = 40.50 μV / °C
Measurement time (time constant): 2 seconds (for air at room temperature and one atmosphere of pressure moving with a velocity of 65 ft / sec)
Maximum temperature of bead: 260°C (500°F)
