Bently Nevada 89477-50 Piezoelectric velocity sensor

The 3500/22M 138607-01 Transient Data Interface (TDI)   is the interface between the 3500 monitoring system and   compatible software (System 1 Condition Monitoring   and Diagnostic software and 3500 System Configuration   software). The TDI combines the function of a 3500/20   Rack Interface Module (RIM) with the data collection   capability of a communication processor such as TDXnet.

3500/22M is a Transient Data Interface Module manufactured and designed by Bently Nevada as part of the 3500 Series used for monitoring seismic activity.

The 3500/33 16-Channel Relay Module is a full-height module   that provides 16 relay outputs. You can place any number of   16-channel relay modules in any of the slots to the right of the   Transient Data Interface (TDI) Module.   Each output of the 3500/33 16-Channel Relay Module can be   independently programmed to perform voting logic.

The 3500/60 & 61 modules provide six channels of   temperature monitoring and accept both Resistance   Temperature Detector (RTD) and Thermocouple (TC)   temperature inputs.  The modules condition these inputs and   compare them against user-programmable alarm setpoints.    The 3500/60 and 3500/61 provide identical functionality   except that the 3500/61 provides recorder outputs for each of   its six channels while the 3500/60 does not.

The 3500/72M Recip Rod Position Monitor meets API 618   requirements for reciprocating compressors. It measures:   l Rod position   l Rod drop   l Hyper-compressor   The four-channel 3500/72M Recip Rod Position Monitor   accepts input from proximity transducers, conditions the   signal to provide dynamic and static position measurements,   and compares the conditioned signals with userprogrammable alarms.   Each channel, depending on how you configure it, typically   conditions its input signal to generate various parameters   called measured values.

The 3500/62 Process Variable Monitor is a 6-channel monitor   for processing machine critical parameters that merit   continuous monitoring, such as pressures, flows,   temperatures, and levels. The monitor accepts +4 to +20 mA   current inputs or any proportional voltage inputs between -10   Vdc and +10 Vdc. It conditions these signals and compares   the conditioned signals to user-programmable alarm   setpoints.
