Technical Note00840-2700-4811, Rev ABPower and transient ProtectionJuly 2015 Best Practices for Power and transient protection on rosemount radar Transmitters1 IntroductionThis document describes best Practices for Power and transient protection on rosemount radar Level Transmitters. Various natural events produce excess transient energy that can enter transmitters via multiple paths. It is critical to practice good grounding techniques in order to optimize the transmitters built-in transient protection . Improper Practices can lead to field failures such as erratic mA readings, spiking, difficulty communicating, and possible incorrect levels. This document outlines these best Practices and can be used as a guideline during radar installation and ground in accordance with Hazardous Location Certifications, national, and local electrical Technical Note00840-2700-4811, Rev ABPower and transient ProtectionJuly 2015 Power and transient Protection2 Sources of transientsThere are several ways transient energy can enter a level transmitter and cause damage to the electronics.
