80PK-10
Type K Thermocouple Pipe Clamp Temperature Probe
Instruction Sheet
Introduction
XW
Warning
To avoid electric shock, do not
use this probe when voltages
exceeding 24 V ac or 60 V dc are
present. The probe is electrically
connected to the output terminals.
The 80PK-10 Type K Thermocouple Pipe Clamp
Temperature Probe (Figure 1) is designed to reliably
measure the temperature of pipes 1.25-inch (32 mm)
to 2.5-inch (64 mm) in diameter, at temperatures
between -29
°
C and 149
°
C (-20
°
F and 300
°
F),
while retaining a long service life.
