This document contains information on the operation, installation and
maintenance of the DP1008 / DC1008 / DD1008 series of 25 mm proximity probe
products.
25mm Proximity Probe Series Overview
The DP1008 / DC1008 / DD1008 series proximity probe products utilize an eddy
current that produces a negative voltage that is directly proportional to the “gap”
distance between the probe and measured surface. The assembly consists of a
proximity probe, extension cable and driver. The driver is a three- or four-wire
device with connections for power, common, and signal output. The driver is
intended for use with a DC negative voltage power supply.

Installation Information
For most applications, it is recommended that the driver be mounted in a protective housing.
More than one driver may share a single housing/enclosure to simplify installation. See PXE
Series Enclosures. The drivers are typically din rail mounted in the enclosure. Connection to
the probe is established when the integral cabling or a proximity probe or an extension cable are
connected to the prox connector on the driver. Excess proximity probe cables should be coiled
up inside the housing/enclosure. Do not cut any cable in a probe system, doing so will
affect system accuracy.
Note: Only PRO DP series and DC series proximity products should be used for the PRO
DD series drivers. Only Bently™ Compatible DX series products should be used with
each other. Bently™ 3300XL products can be used with the PRO DX series. Substitute
cables from other sources should not be used. PRO products are not electrically
compatible with other sources and will affect system accuracy.
All connector connections should be tight and secure. Snug the connector screw collar, applying
5 in-lbs (0.6 N-m) of torque.
Note: Do not overtighten the probe cable connection. Do not exceed a torque of 8 in-lbs.
(0.9 N-m). Too much torque can cause damage.Probe connectors must not touch any
machine metal parts. Proper steps should be taken to isolate connectors from metal
surfaces. Connector protectors are available per request.
Probes are provided with a threaded SST case. These can be mounted directly through the
machine housing via threaded hole. When installing this way, proper clearance (1.5 x tip
diameter; e.g. 1.5 x 8mm probe tip = 15mm clearance) around the probe tip must be provided.
Refer to the figure below.

For most applications, the driver is recommended to be mounted in a protective
housing. More than one driver may share a single housing/enclosure to simplify
installation. CTC offers an extensive line of probe driver enclosures in the PXE
series. The drivers are typically DIN rail mounted in the enclosure. Connection
to the probe is established when the integral cabling of a proximity probe or an
extension cable is attached to the driver’s probe connector. Excess proximity
probe cabling should be coiled up inside the housing/enclosure. Do not cut any
cable in a probe system. Doing so will affect system accuracy.
Note: Only PRO DP series and DC series proximity products should be used
for the PRO DD series drivers.
All connector connections should be tight and secure. Snug the connector screw
collar, applying 5 in.-lbs (0.6 N-m) of torque.
Note: Do not overtighten the probe cable connection. Too much torque
may cause damage. Do not exceed a torque of 8 in.-lbs (0.9 N-m). Probe
connectors must not touch any machine metal parts. Take proper steps to
isolate connectors from metal surfaces. Connector protectors are available
upon request.
Probes are provided with a threaded stainless steel case. These can be mounted
directly through the machine housing via a threaded hole. When installing this
way, give the proper clearance of 1.5 times the tip diameter around the probe tip
(e.g., 1.5 x 25 mm tip diameter = 37.5 mm clearance). Refer to the figure below.

Electrical Connections
The DP100880 Probe Driver utilizes eddy current principles to produce a linear
negative voltage output proportional to the displacement between the probe
tip and the measured surface. The driver is a three-wire system that adheres to
API670 standards with connections for power, common, and signal output.

Target Surfaces
The target material directly affects the output from the proximity probe system.
Drivers can be calibrated for many different target materials. If the target material
differs from the material the driver is calibrated to, the output will become
non-linear. Please see the complete list of compatible materials at ctconline.com.
For vibration monitoring of rotating shafts, the observed surface must have
a roughness not to exceed 32 µin. (< 1 micron) and must be concentric. False
vibration readings will result if the surface is rough or has discontinuities or
excessive mechanical run-out. The target area should be at the circumference
of a shaft and perpendicular to the probe tip to ensure measurement accuracy.
Linear range may be reduced if the target diameter < 0.5 in. or shaft diameter
< 1.2 in.
Note: Shaft diameters should be uniform in the target area and free of
keyways, oil slingers, or mechanical damage.
Setup and Adjustment
When all connections to the driver have been made and the probe is in place,
apply power to the system. For applications where the only data of interest is
vibration level, where measuring the gap is unnecessary, the voltage at the OUT
(signal output) terminal, relative to the COM (common) terminal, should be -7.0
±5 V for a mid-range gap of 35 mils. Adjust the probe until this reading is obtained.
For applications where the actual gap needs to be measured, adjust the probe
until a reading is obtained that reflects the desired initial gap setting.

Target Surfaces
The target material directly affects the output from the system. Drivers are calibrated for SAE
4140 steel. If the target material differs from SAE 4140 steel, the output will become non linear
NOTE: Shaft diameters should be uniform in target area, and free of keyways & oil
slingers or mechanical damage.
Setup and Adjustment
25mm proximity probes are typically used for measuring differential expansion on steam
turbines. This is the measurement of the difference in the rotor expansion and casing
expansion.
When all connections to the driver have been made, and the probe is in place, apply
power to the system. Adjust the probe until the appropriate output is obtained.

A PRO DP Probe Assembly operates in combination with a PRO DD Probe driver.
The driver outputs a signal proportional to the gap between the probe tip and
the target. The average gap corresponds to the DC component of the output.
Vibration is measured by monitoring the DC variation of the signal simulating an
AC component. All drivers have the same 13 V output span. The output sensitivity
of the 25 mm driver is -20 mV/mil.
