Rheonics Sand Detector Probe (SDP) is a switch level sensor used to detect the accumulation or presence of particles in fluid e.g. sand in a desander vessel or pipelines used in oil and gas industries. Rheonics SDP is designed to sustain high pressure environments such as those found in desanders. Rheonics Ostrich software that comes with the sensor makes real-time monitoring possible and recognitizion of phases in the fluid such as oil, water, sand, or a mix of them. Learn more on Rheonics SDP.

Rheonics SDP is offered with the SDP-X9 probe and the HP weld adapter (HPWA-SDP). The protection sleeve (SPS-SDP) may also be used in order to protect the probe from unwanted collisions during handling. Product number: SDP-X9-STD.
