Abstract
Abstract A pressure transducer comprises a sensor (16), an electronic circuitry part (17), a pressure connection (13), and an electrical connection (14). According to the invention, the transducer is constructed as a plug-in unit (5) and both the pressure connection and the electrical connection (14) are designed integral with the socket (6). The plug-in unit (5) may incorporate a splash-water protection (8) with a latch mechanism (9) for locking the plug-in unit (5) and the socket (6).

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
162 words
A pressure transducer comprising: (a) a box-like socket having an upper side, an external pressure connection, first internal pressure connection means at the upper side and being connected to the external pressure connection, external electrical conductors, and first internal electrical connection means at the side and being connected to the conductors; and (b) a plug-in unit having a box-like splash-water protection sheath open at one side thereof, said sheath having internal dimensions at least approximately corresponding to external dimensions of the box-like socket, an electronic circuitry port provided inside the sheath, second internal pressure connection means, and second internal electrical connection means, the sheath of the plug-in unit being placed over the box-like socket to encase the socket from above and from the sides thereof, the second internal pressure connection means being received in the first internal pressure connection means and the second electrical connection means being received in the first electrical connection means when the sheath is over the plug-in unit.
Claim 2
Dependent Claim
162 words
A pressure transducer comprising: (a) a box-like socket having an upper side, an external pressure connection, first internal pressure connection means at the upper side and being connected to the external pressure connection, external electrical conductors, and first internal electrical connection means at the side and being connected to the conductors; and (b) a plug-in unit having a box-like splash-water protection sheath open at one side thereof, said sheath having internal dimensions at least approximately corresponding to external dimensions of the box-like socket, an electronic circuitry port provided inside the sheath, second internal pressure connection means, and second internal electrical connection means, the sheath of the plug-in unit being placed over the box-like socket to encase the socket from above and from the sides thereof, the second internal pressure connection means being received in the first internal pressure connection means and the second electrical connection means being received in the first electrical connection means when the sheath is over the plug-in unit.
Claim 3
Dependent Claim
34 words
The pressure transducer as claimed in claim 1, further comprising a latch mechanism cooperated with the sheath and positioned between the plug-in unit and the socket when the sheath is over the plug-in unit.
Claim 4
Dependent Claim
15 words
The pressure transducer as claimed in claim 1, wherein the socket incorporates a splash-water protection.
Claim 5
Dependent Claim
38 words
The pressure transducer as claimed in claim 3, further comprising a latch mechanism cooperating with the splash-water protection of the socket and positioned between the plug-in unit and the socket when the sheath is over the plug-in unit.
Claim 6
Dependent Claim
27 words
The pressure transducer as claimed in claim 1, wherein the second internal pressure connection means is sealed with the first internal pressure connection means by an O-ring.
Claim 7
Dependent Claim
18 words
The pressure transducer as claimed in claim 1, wherein the socket is mountable onto its base by screws.
