ELSNER 70153 KNX SO250 basic ultrasonic tank probe

Knx Level sensor

Description

The KNX SO250 basic ultrasonic probe is used to record the fill quantity of liquids in tanks and to measure distances. The probe head is resistant to heating oil and water and can e.g. B. be used for water storage, ponds or oil tanks. Five limit values ​​can be set for filling, emptying, dry run protection and overflow reporting.

Functions:
– Distance measurement
– Level measurement in spherical, rectangular and cylindrical tanks. Several tanks of the same type as a battery
– 5 switching outputs with adjustable limit values ​​(limit values ​​are set either by parameters or via communication objects)

Scope of delivery:
– Evaluation unit in a modular housing
– Ultrasonic probe with 10 m connection cable
