Siemens SITRANS LVL200 Vibrating Fork Point Level Switch for Liquids and Slurries

Siemens' SITRANS LVL200 is a vibrating tuning fork  level switch for use in liquid and slurry applications like overflow, high, low, demand, and pump protection. Its short insertion length (just 1.57") makes the SITRANS LVL200 easy to mount in small pipes or confined spaces.

SITRANS LVL200 continuously monitors faults via frequency evaluation, providing early detection of strong corrosion or damage on the tuning fork, loss of vibration, or a line break to the piezo drive. It can be used in difficult conditions including turbulence, air bubbles, foam generation, buildup, or strong external vibration.

SITRANS LVL200 comes in three output versions: DPDT relay output with two floating SPDTs, contactless electronic switch, and two-wire NAMUR signal output.
