Abstract
A non-intrusive milk flow sensor includes first and second cylindrical nipples of a conductive material. Each of the first and second cylindrical nipples has an inner diameter. A molded rubber body has a passage therethrough joining the first and second nipples. The body fixes the first cylindrical nipple inline with the second cylindrical nipple and is bonded with the nipples. The body has an inner diameter defined by the passage equal to the inner diameter of the first and second cylindrical nipples. The molded rubber body insulates the first cylindrical nipple from the second cylindrical nipple. A first electrical lead is connected to the first cylindrical nipple. A second electrical lead is connected to the second cylindrical nipple.
Claims16
In a milk flow sensor including
- first and second cylindrical nipples of a conductive material each having an inner diameter,
- a body connecting the first cylindrical nipple with the second cylindrical nipple and insulating said first cylindrical nipple from said second cylindrical nipple,
- a first electrical lead connected to said first cylindrical nipple, and
- a second electrical lead connected to said second cylindrical nipple, an improved milk flow sensor wherein:
- said body is molded and has a passage therethrough joining the first and second nipples, said passage defining an inner diameter equal to the inner diameter of the first and second cylindrical nipples, said body being bonded to and fixing said first cylindrical nipple inline with said second cylindrical nipple.
A non-intrusive milk flow sensor including:
- first and second cylindrical nipples of a conductive material and each having an inner diameter;
- a molded body having a passage therethrough, bonded to and joining the first and second nipples, said body fixing the first cylindrical nipple inline with the second cylindrical nipple and having an inner diameter defined by said passage equal to said inner diameter of said first and second cylindrical nipples, said molded body insulating said first cylindrical nipple from said second cylindrical nipple;
- a first electrical lead connected to said first cylindrical nipple;
- and
- a second electrical lead connected to said second cylindrical nipple.
A method of making a milk flow sensor comprising the steps of:
- a) providing first and second cylindrical nipples each having an inner diameter;
- b) mounting the first and second cylindrical nipples on an assembly fixture;
- and
- c) forming a body extending around and bonded to the first and second nipples with a passage defining an inner diameter equal to the inner diameter of the first and second nipples.
