ABSTRACT:
The present invention is directed to a detector for the detection of abrasive material being carried by fluid passing through a wellhead, the detector including an erosion block having a passage therein and a bore intercepting the passage; a probe which is inserted into the bore of the erosion block, this probe having a contact zone exposed to the passage when the probe is inserted in the bore and a first bore extension inboard of the surface of the contact zone which communicates with a first bore; and a first pressure transducer provided for sensing pressure in the first bore and in the first bore extension connected thereto; the pressure transducer providing an electrical output indicative of a change in pressure in the first bore and being electrically coupled to a device which is responsive to the electrical output of the first pressure transducer.
