MVI – Improved temperature stability MVI stands for „Mains power Variance Immunity”
MVI – Improved temperature stability
Dual-zone heating block
Unstable mains power supplies are a major
contributor to on-site calibration inaccuracies.
Traditional temperature calibrators often become
unstable in production environments where large
electrical motors, heating elements, and other
devices are periodically cycled on or off. The
cycling of supply power can cause the
temperature regulator to perform inconsistently
leading to both inaccurate readings and unstable
temperatures.
The specialized block design increases the
temperature homogeneity in the critical
calibration zone. It also minimizes the need to
insulate the sensor-under-test and makes it
possible to calibrate liquid-filled and other
mechanical sensors.
The main, or lower, zone ensures optimum heat
dissipation throughout the entire block. The
secondary, or upper, zone compensates for the
heat loss from the top of the block and from the
sensor-under-test
