3309 (Focus View) Specifications and Dimensions

Specifications

Parameter	Value
Linear Range	2.0 mm (80 mils). Linear range begins at 0.38 mm (15 mils) from target and is from 0.38 to 2.41mm (15 to 95 mils).
Incremental Scale Factor (ISF)	7.87 V/mm (200 mV/mil) +12.5%/–20% including interchangeability error when measured in increments of 0.25 mm (10 mils) over the 1.5 mm (60 mils) linear range
Deviation from best fit straight line (DSL)	Less than ±0.06 mm (± 2.3 mils)
Frequency response	0 to 10kHz (-3 dB) typical, with up to 100 meters (300 feet) of field wiring.
Target Size	Minimum: 8.9 mm (0.35 in) diameter Recommended minimum: 13mm (0.5 in) diameter Axial position measurements on shaft diameters smaller than 13mm (0.5 in) will generally result in a change in scale factor. Reducing the gap between the probe and target will help limit the change in scale factor.
Shaft Diameter	Minimum (standard X-Y probe configuration): 30 mm (1.2 in) Minimum (X-Y proximity probes offset axially by 23 mm (0.9 in)): 20 mm (0.8 in) Measurements on shaft diameters smaller than 30 mm (1.2 in) usually require close spacing of radial vibration or axial position transducers. This creates the potential for their electromagnetic emitted fields to interact with one another (cross-talk), resulting in erroneous readings. To prevent cross-talk, maintain minimum separation of m transducer tips of at least 25 mm (1.0 in) for axial position measurements or 23 mm (0.9 in) for radial vibration measurements
Probe Tip Material	Polyphenylene sulfide (PPS).
Probe Cable Specifications	75 Ω coaxial, fluoroethylene propylene (FEP) insulated probe cable in the following total probe lengths: 0.5, 1, 5, or 7 meters.
Extension Cable Material	75 Ω coaxial, fluoroethylene propylene (FEP) insulated.
System Length	5 or 7 meters including extension cable
Extension Cable Armor (optional)	Flexible AISI 302 SST with/without FEP outer jacket
