Abstract

A retainer holds an electronic communication device used to detect breaks in porous elements of material separators to the frame of the separator. The retainer includes a ferrule affixed around a hole through the frame of the separator, a housing made from an RF transmissible material sealingly held within the ferrule, and a cap sealingly held against the ferrule. The electronic component is held by the cap such that it is situated within the housing. Such a retainer is affixed to frames of the separator on opposing sides of a porous element so that a transmitter may be retained in a first retainer and a receiver retained in a second retainer. The transmission of a signal from the transmitter that is received by the receiver indicates a break in the porous element between the components.

Claims

1. A retaining system for a transmitter and a receiver for detecting an RF path through a porous element in a material separator, wherein the material separator includes a first frame having a first frame wall and a second frame having a second frame wall, wherein the porous element is received between the first frame wall and the second frame wall such that a first chamber and a second chamber are defined, the retaining system comprising:

a first retainer within which the transmitter is housed, wherein the first retainer is affixed about an RF path through the first frame wall and provides a barrier to RF signals outside of the RF path through the first frame wall;

wherein the first retainer comprises;

a first ferrule having a first end affixed around the RF path through the first frame wall and a second end extending outward from the first frame wall;

a first housing sealingly retained within the first ferrule and separating the transmitter from the first chamber;

a first cap sealingly retained against the second end of the first ferrule and retaining the transmitter within the first housing and having a connector opening therethrough retaining a transmitter communication connector providing data exchange between the transmitter and an external device; and

a second retainer within which the receiver is housed, wherein the second retainer is affixed about an RF path through the second frame wall and provides a barrier to RF signals outside of the RF path through the second frame wall.

2. A retainer system as in claim 1, wherein the second retainer comprises:

a second ferrule having a first end affixed around the RF path through the second frame wall and a second end extending outward from the second frame wall;

a second housing sealingly retained within the second ferrule and separating the receiver from the first chamber;

a second cap sealingly retained against the second end of the second ferrule and retaining the receiver within the second housing and having a connector opening therethrough retaining a receiver communication connector providing data exchange between the receiver and an external device.

3. A retainer system as in claim 1, wherein the first ferrule and the second ferrule are each formed from an RF blocking material;

and

wherein the first housing has a faceplate between the transmitter and the first chamber and the second housing has a faceplate between the receiver and the second chamber, each faceplate being formed from an RF transmissible material.

4. A retainer system as in claim 1, wherein the first ferrule includes an outwardly extending flange to which the first cap is sealingly retained;

and

wherein the second ferrule includes an outwardly extending flange to which the second cap is sealingly retained.

5. A retainer system as in claim 4, wherein the first and second housings each include an outwardly extending housing flange, the housing flange of the first housing sealingly retained between the flange of the first ferrule and the first cap and the housing flange of the second housing sealingly retained between the flange of the second ferrule and the second cap.
