2.5.1 Spark Protector
for Integral Units
Applications involving insulating granulars and insulating
liquids may require extra spark protection against static
discharge that can damage the electronic unit. If required, a
heavy duty spark protector is available as an option and will
be prewired at the factory with integrally mounted Ztron level
controls. Figure 2-12 shows an integral Ztron control wired
with optional spark protector (377-1-24).
