Product Description
Application: The level switch operates in process temperatures of –40 to 302 °F (–40 to 150 °C), and can be mounted in an open or closed tank, or a pipe. There is a wide range of threaded, flanged, and hygienic process connection options.
Features:
- Designed for use in process temperatures of –40 to 302 °F (–40 to 150 °C)
- Based on vibrating short fork technology, the level switch is suitable for many liquid applications
- Virtually unaffected by flow, bubbles, turbulence, foam, vibration, solids content, coating products, liquid properties, and product variations
- A ‘heartbeat’ LED indicates its operating state. The LED also flashes when the switch output is ‘off’ and is constantly lit when 'on'
- ‘Fast drip’ fork design gives quicker response time, especially with viscous liquids. Rapid wet-to-dry and dry-to-wet time setting for highly responsive switching
- Adjustable switching delay prevents false switching in turbulent or splashing applications
- Fork shape is optimized for polishing to meet hygienic requirements. There are mechanical- and electro-polishing options
- Magnetic test-point for easy functional test
- No moving parts or crevices for virtually no maintenance
- No need for calibration and requires minimum installation procedures
- Easy terminal access and electrical protections (see page 37)
- Short fork length with extensions up to 157.5 in. (4 m)
- General area, explosion-proof/flameproof and intrinsically safe options
- Tri Clamp process connections are available as hygienically certified to 3-A® and EHDEG, and compliant with FDA and ASME BPE
This combination of features makes the Rosemount 2120 Level Switch an ideal choice for a wide variety of challenging applications in the chemical, power generation, and oil and gas industries.
