Sand Probes for Control Systems
 Continuous monitoring of the effects of an abrasive product on flowline and valves is possible with the use of the sand probe. A sensing probe of a predetermined thickness extends into the flow path of the abrasive product. When the probe has been cut, indicating a known degree of erosion, the sand probe assembly shifts, blocking and bleeding a control pressure signal. This signal is used to either close a valve or trigger an alarm. The assembly is available for use with either low or high pressure control systems.
