The hydrostatic level probe with G ½“ thread has been developed to meet the high demands of industry and environmental protection.
The corrosion-proof encapsulation featuring IP68 protection rating allows to use the unit for reliable level detection in containers and tanks
The probes are particularly suitable for pressure investigation in closed systems and pipelines.
Due to the use of piezo-resistive measurement cells made of stainless steel (1.4404) the UniBar E II has proven very well for use under extremem conditions in aggressive media such as acids and caustic solutions..
Electric connection is made by using screw clamps in a stainless steel enclosure or plugs according to DIN ISO 4400. There are four standard measurement ranges available. The probes can be also calibrated on customer request.
Utilising the widely used 2-wire technology, the installation costs are very low.
The unit is optionally available with a 4-character LCD integrated into the enclosure lid for indication of measurement values.
