SITRANS LVL200S l RELAY (DPDT)
4 Mounting
4.1 General instructions
In general, SITRANS LVL200S can be installed in any position.
The instrument simply has be mounted in such a way that the
tuning fork is at the height of the desired switching point.
The tuning fork has lateral markings (notches) that indicate the
switching point with vertical mounting. The switching point
refers to water with the basic setting of the sensitivity switch
≥ 0.7 g/cm³ (0.025 lbs/in³). When mounting SITRANS
LVL200S, make sure that this marking is at the height of the
requested switching point. Keep in mind that the switching
point of the instrument is shifted if the medium has a density
other than water - water 1 g/cm³ (0.036 lbs/in³). For products
< 0.7 g/cm³ (0.025 lbs/in³) and > 0.5 g/cm³ (0.018 lbs/in³) the
density switch must be set to ≥ 0.5 g/cm³.
Keep in mind that foams with a density > 0.45 g/cm³ (0.016 lbs/
in³) are detected by the sensor. This can cause faulty
switchings particulary when used as dry run protection system.
