1. General Introduction
Rosemount 2130 vibrating fork level switch is enhanced version specially challenging applications of tough operating conditions and safety critical environments, it is virtually unaffected by turbulence, foam, vibration, solids content, coating products, and liquid properties. The mid-range temperature Rosemount 2130 is designed for operation in process temperatures from –40 to 356℉ (–40 to 180℃), The high-temperature Rosemount 2130 is designed for operation in process temperatures from –94 to 500℉ (–70 to 260℃). It has a stainless steel thermal tube to move the electronics away from the process, with increased safety, SIL2-certified to IEC 61508 as required by IEC 61511.
