The measurement of air temperature in and around the nuclear containment area is an important parameter indicating whether a problem has occurred, possibly a line break resulting in steam or coolant water loss.
Delta Controls, one of the leading manufacturers of nuclear qualified instrumentation has, after testing to meet seismic
and radiation exposure requirements, has launched a new fast reaction air temperature switch for the application and has already secured orders for over 250 units for use inside the containment and the nuclear island of an operational BWR reactor.
The Fast Reaction switch offers many advantages over conventional bulb and capillary systems including ease and cost of installation, significantly improved reaction times and high accuracy and repeatability built around Delta’s proven Nuclear Performance Range of switches.
