Features:
- 991 Thrust Transmitter with ±25 mils full-scale range for axial displacement monitoring
- 7.0-meter system length with DIN clip and screw mounting for flexible installation
- CSA Division 2, ATEX Zone 0/2, and ABS maritime approved for hazardous and marine applications
The 991-25-70-03-05 provides essential axial position sensing functions critical to the entire monitoring path, serving as the primary interface between NSv proximity probes and OEM control systems, directly affecting the proper, normal operation of the overall machinery protection scheme. One 991-25-70-03-05 transmitter is required per thrust measurement point, installed on DIN rail in the control cabinet and connected to the 3300 NSv probe via its 7.0 meter system length. The 991-25-70-03-05 features a ±25 mils full-scale range, providing appropriate scaling for centrifugal compressor and pump thrust monitoring applications.
For applications requiring hazardous area compliance, the 991-25-70-03-05 carries CSA Division 2, ATEX Zone 0, ATEX Zone 2, and ABS maritime approvals for use in explosive atmospheres and marine environments. In addition to standard thrust monitoring, the 4-20 mA output of the 991-25-70-03-05 enables direct connection to existing PLC and DCS analog inputs without requiring specialized monitoring hardware. The two-wire loop-powered design simplifies wiring and reduces installation costs.
The 991-25-70-03-05's robust design ensures reliable operation in OEM applications. Users should note that while the 991-25-70-03-05 provides reliable thrust measurement, advanced monitor functions such as Timed OK channel defeat, Danger Bypass, and Trip Multiply cannot be used, and the transmitter is not suitable for plant-wide diagnostic systems such as System 1 or Rule Paks. The 991-25-70-03-05 remains a practical solution for OEMs requiring simple axial position alarming with global hazardous area approvals.
The 991-25-70-03-05 Bently Nevada Thrust Transmitter may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).
