Lightning/surge protected transducers
Hampton, Va. - Series 27 aboveground pressure transducers are available with lightning protection. The option guards against lightning strikes and power surges for the life of the device. It is especially useful for applications that present difficulties with such protection, as when a transducer is mounted on an elevated storage tank. The Series 27 devices feature surge protection against fast rising voltage transients, as well as severe current surges associated with lightning. The protectors are a multistage design, with a solid-state section that intercepts the leading edge of the surge within nanoseconds. The second stage contains a gas discharge tube that 'crowbars' up to 20,000-amp currents to ground.
