Dual-zone heating block
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
