The 3300 XL 50 mm transducer system consists of a 50 mm probe, extension cable and 3300 XL 50 mm Proximitor Sensor. The Proximitor accepts one noncontacting probe-and-cable assembly and converts the proximity signal for monitoring use. In 330878-X0-00, the X character leaves the exact 5 m or 9 m system-length choice unresolved; the fixed 0 identifies the panel-mount family option. Option 00 means no approvals. MOD 177889-01 is subject to nameplate and documentation verification.
|
System interface
|
Accepts one 3300 XL 50 mm probe and compatible extension cable.
|
|
Mounting
|
Thin panel-mount Proximitor configuration; exact X system length is subject to verification.
|
|
Linear range
|
27.9 mm (1100 mils).
|
|
Scale factor
|
394 mV/mm (10 mV/mil) nominal.
|
|
Connections
|
SpringLoc terminals support field wiring without special installation tools.
|
|
Immunity
|
Improved RFI/EMI immunity and European CE-mark compliance.
|
|
Calibration
|
Factory calibration defaults to an AISI 4140 steel target.
|
The probe and extension cable form an eddy-current proximity transducer with the Proximitor Sensor. The system measures the changing distance to a conductive target. The Proximitor conditions this signal into a voltage suitable for differential-expansion or rotor-expansion monitoring. Correct system length, target material, probe position and cable matching are required for the documented performance.
|
Power without barriers
|
-17.5 to -26 Vdc, 12 mA maximum.
|
|
Power with barriers
|
-23 to -26 Vdc.
|
|
Output resistance
|
50 ohm.
|
|
Linear range
|
1.3 to 29.2 mm from target, approximately -1.5 to -12.5 Vdc.
|
|
Recommended target
|
AISI 4140 steel, 102 mm diameter or larger.
|
|
Extension-cable capacitance
|
69.9 pF/m typical.
|
|
Field wiring
|
0.2 to 1.5 mm2 (16 to 24 AWG), shielded three-conductor triad recommended.
|
|
Proximitor material
|
A380 aluminum.
|
|
System length
|
5 or 9 m, exact X option subject to verification.
|
A high-frequency oscillator in the proximity system produces an eddy-current field at the probe tip. Changes in distance to the conductive target alter the system response. The Proximitor converts this change to a proportional voltage. The 50 mm coil geometry provides the long linear range required for large differential-expansion measurements.
|
Probe temperature
|
-35 to +200 degrees C continuous; +250 degrees C for less than 24 hours.
|
|
Proximitor operating temperature
|
-51 to +100 degrees C.
|
|
Probe-tip material
|
Polyphenylene sulfide.
|
|
Probe-case material
|
AISI 304 stainless steel.
|
|
Cable construction
|
75-ohm PFA-insulated FluidLoc cable.
|
|
Minimum bend radius
|
25.4 mm.
|
|
Agency option
|
00 means no approvals.
|
