Point Level Sensor with Fault Monitoring/Self-checking Diagnostics
Emerson Process Management has launched an extreme temperature version of its Rosemount 2130 vibrating fork liquid level switch, which is designed for use in extreme temperatures from -94 to +500 °F ( -70 to + 260 °C). The version has built-in fault monitoring/self-checking diagnostics, making it an ideal choice for a variety of challenging applications in the chemical, power generation and oil and gas industries.
The switch is simple and easy-to-use, reliable in a range of applications and requires no on-site calibration. Addition of the extreme temperature version allows site managers the possibility to standardize on the Rosemount 2130 across a range of process environments.
The Rosemount 2130 “heart-beat” LED gives an instant visual indication that the unit is operational. In addition, the built-in fault monitoring/self diagnostics can detect any corrosion of the forks or any other internal or external damage or breaks in the internal electrical wiring, which triggers a warning LED and fail-safe handling of the load.
Further functionality includes a low-density option suitable for liquids with a specific gravity down to 0.5 (500 kg/m3) and a choice of electronic output options for use on their own or as part of an analogue or digital plant monitoring network. The model is available in 316L stainless steel or corrosion-resistant alloy C wet side with a choice of aluminium or stainless steel housing options.
