Introducing a new addition to the Jumo NESOS series of float switches. The R40 LSH now includes devices for point level measurement such as floats and reed contact. The series also includes devices for level measurement such as float and reed chain. The unit is particularly easy to mount so that it can be used in a wide variety of industries.

The horizontal design allows mounting on the side walls of tanks and containers where it can be reliably measure the respective point levels (min/max). The measurement is independent of many media properties, pressure conditions and container geometries. It provides up to 2 switching contacts for that do not require auxiliary power, for redundant level measurement.

The NESOS R40 LSH is available with a guide tube length of up to 1 m. The device can be operated at temperatures from -52 to +240 °C and process pressures of up to 88 bar. It is available in protection classes IP65 and IP68 and optionally with ATEX as well as IECEx approval (Ex i) and (Ex d) for use in zone 0. Consequently, the unit guarantees a particularly high level of process reliability. A version with a temperature probe/switch is also part of the product range. As a result, no additional tank or container opening is requited for temperature measurement.

The maintenance-free device design and simple mounting saves on costs. Storage costs can also be reduced by using the min/max level with a variant. The float switch is individually adaptable to many applications in the chemical and petrochemical industries as well as in mechanical engineering and container construction.
