regulators. Additionally, they
can
serve as temperature sensing elements in assembled
th
ermocouples, capable of measuring the temperature of liquids,
steam,
g
as media, and solid surfaces within a range of 0°C to 1300°C
across various industrial
pro
cesses.
Features:
Minimal thermal response time, reducing dynamic error
Flexible and easy installation
Wide measuring range
High mechanical strength with exceptional pressure resistance
