Abstract
The present invention is an elastic seal for use with a sanitary probe. The elastic seal forms a layer between the probing member and the coating member to eliminate the formation of voids between the two. The elastic seal may include an elastic substance, such as silicon or rubber, to enable it to remain in contact with both the probing member and the coating member in the case that a change in temperature causes either or both to expand or contract. The elastic seal may have a coefficient of thermal expansion that is intermediate to a coefficient of thermal expansion of the probing member and a coefficient of thermal expansion of the coating member. The elastic seal prevents voids from forming in the probe assembly into which outside materials may enter.
Claims22
A seal for use with a probe assembly having a probing member and a coating member, the seal comprising:
- an elastic member between the probing member and the coating member.
A seal for use with a sanitary probe assembly having a probing member and a coating member, the seal comprising:
- an elastic member between the probing member and the coating member, the elastic member having a coefficient of thermal expansion intermediate to a coefficient of thermal expansion of the probing member and a coefficient of thermal expansion of the coating member.
A probe assembly, comprising:
- a probing member for probing a substance;
- an elastic seal surrounding at least a portion of the probing member;
- and
- a coating member surrounding at least a portion of the elastic seal.
A method for making a sanitary probe, the method comprising the steps of:
- providing a probing member;
- covering at least a portion of the probing member with an elastic seal;
- and
- covering at least a portion of the elastic seal with a coating member.
