Resonator line of vibrating liquid level switches is intended for chemical and petrochemical applications, including high-viscosity environments to 20,000 cP. Product family includes RS80 vibrating liquid level switch and RS85 multi-option vibrating liquid level switch. Both are based on tuning fork design. RS85 also provides a wide selection of probe materials to make the switch immune to coating or build-up and ensure accurate, repeatable operation for measuring water, thick lubricants, or sticky slurries. Line features one-step, external calibration and can handle challenging applications such as sump level control, air entrainment, and overfill protection. Built-in, self-test option automatically checks for fault conditions. It comes in 120- and 240-V ac, 24-V dc, and loop power configurations.
