Product Type: 3300 XL Proximity ® sensor

Bentley bently3300 high temperature resistance eddy current sensor

The 3300 high temperature eddy current system can be used for eddy current measurement in high temperature areas, and has quite ideal measurement results. Benefits for users include:

1. Eddy current probes with integral hard wire cables can continuously withstand high temperatures in harsh environments of +350 ° C (+662° F) under conditions

2, 4mm (160 mils) linear range, can be measured in most parts of the high-temperature machine wide range •

3, sealed ceramic probe end, moisture and pollution prevention, can extend the service life •

4, ceramic end and stainless steel structure, heat, moisture and corrosion resistance. •

5, with threaded and unthreaded housing, suitable for a variety of probe mounting types

6, the length of 1, 2 or 5 meters of hard wire cable can be used to lead from the high temperature parts of the machine

3.94 V/mm (100 mV/mil) signal output, compatible with virtually all new and existing Bently Nevada monitoring and diagnostic equipment.

Electrical characteristics of Bentley 3300 high temperature preprocessor

Preprocessor input

Receive non-contact 3300 HTPS 16mm eddy current probe with matching extension cable.

Power source

Requirements -19.6 Vdc to -26 Vdc, the current is 12 mA. Operating at positive voltages higher than -23.5 Vdc results in reduced linear range.

Power supply sensitivity

For every 1 volt change in the input voltage, the output voltage changes not more than 13 mV.
