Features:
- Two-wire, loop-powered design with 4-20 mA output proportional to shaft axial position for simple integration into OEM control systems.
- 35 mm DIN rail mounting enables quick, tool-free installation in control panels without special hardware or drilling.
- PROX OUT coaxial connector provides access to a non-isolated dynamic transducer signal for troubleshooting and diagnostics using test equipment.
The 991-01-XX-01-00 MOD: 284318-01 is purpose-built for OEMs who need to provide axial position monitoring without the complexity of a full continuous monitoring system. Its two-wire, loop-powered design simplifies wiring, requiring only a 4-20 mA loop connection to the control system for both power and signal.
The 991-01-XX-01-00 MOD: 284318-01 mounts on standard 35 mm DIN rail clips, enabling rapid installation without screws or specialized tools. This is particularly advantageous for OEMs building control panels in high volumes, where installation time directly affects production efficiency.
Despite its simplified design, the 991-01-XX-01-00 MOD: 284318-01 includes a PROX OUT coaxial connector that provides access to the non-isolated dynamic transducer signal. This feature allows technicians to connect battery-powered or isolated test equipment directly to the transmitter for troubleshooting, enabling verification of probe gap, cable integrity, and transducer response without interrupting the 4-20 mA loop to the control system.
The 991-01-XX-01-00 MOD: 284318-01 Bently Nevada 991 Thrust Transmitter may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Key Rotary Machinery: Widely used in centrifugal air compressors, small pumps, motors, fans, and blowers.
- Axial Position Monitoring: Specifically designed to monitor the axial (thrust) displacement of units equipped with fluid-film bearings to prevent destructive collisions between the rotor and stator.
- System Integration: Directly inputs signals to PLC, DCS, or SCADA
- High-precision conversion: Full-range accuracy
- Prox Out interface: Provides raw dynamic signals and gap voltages, enabling troubleshooting and data analysis without disconnection.
- Environmental adaptability: Utilizes potting technology.
- Space-Constrained Environments: Due to its compact size and support for DIN rail or base plate mounting, it is suitable for installation in confined spaces such as gas compressors.
- OEM Equipment Protection: As a standard feature of small units, it provides cost-effective and efficient continuous online displacement protection without the need for complex rack monitoring systems.
- Remote Monitoring: Suitable for equipment monitoring in remote pumping stations or unattended sites.
