Installing the entire probe in the measurement environment
prevents heat conduction to the sensor, and is the
recommended installation method.
Figure 8: Optional Probe Mounting Clamp
CAUTION: Attaching the probe mounting clamp to a con-
ductive wall material should be avoided, since
the potential galvanic connection to the power
supplies and uncontrolled earth current loops
could cause measurement errors or even dam-
age to an HMT140 transmitter (not the HMT141).
