170172 FieldMonitor Internal 7200 ProximitorModuleBently Nevada Asset Condition Monitoring

DescriptionThe 170172 Internal 7200 Proximitor Module is a dual Proximitor module that willwork with any standard 7200 series 5mm or 8mm probe in 5m and 9m systemlengths. This modules dual internal Proximitor sensors eliminate the need forexternal Proximitor sensors, and allow direct connection of up to two proximityprobes and their associated extension cables.

Specifications

Unless otherwise noted, the following specificationsare for a proximity transducer system at +22C(+72F) with a -24 Vdc power supply, a 10 kload, aGE supplied AISI 4140 steel target and a probegapped at 1.27 mm (50 mils). Typical is defined as

90% of the devices built meeting the specification.The calibration range is 250 m (10 mil)to 2250 m(90 mil), (Approximately 1 to 17 Volt dc).

Incremental

Scale Factor:

7.87 mV/m (200 mV/mil)

6.5% includinginterchangeability error whenmeasured in increments of 0.25mm (10 mils) over the linearrange.

Deviation from

best fit straightline (DSL):

Less than 38 m (1.5 mil)deviation from best fit straightline.

Minimum

Target Size:

15.2 mm (0.6 inch) diameter (flattarget).

Shaft Diameter:Minimum: 50.8 mm (2 inches).

Recommended

minimum:

76.2 mm (3 inches). With XYprobes in the same plane, shaftdiameters smaller than 50.8 mm(2 inches) will experienceelectrical noise due to crosstalk.

Proximitor Sensor

Weight:

353 g (12.7 oz)

StorageTemperature:

-40C to +85C (-40F to +185F)

Operating

Temperature:

-35C to +85C (-30F to +185F)

RelativeHumidity:

100% condensing non-submerged from +7C to +85C(+45F to +185F) when

connectors are protected.Intrinsic safety:

The 1701 Proximitor Sensor isdesigned to be used only with the1701 Internal Galvanic Isolator.
