Description
991-01-XX-01-00 MOD: 284318-01 Thrust Transmitter is a loop-powered axial displacement transmitter designed for automated machinery control and monitoring systems. 991-01-XX-01-00 MOD: 284318-01 accepts input from one non-contacting 3300 NSv proximity probe with a 7.0 m system length and converts shaft thrust movement into a standard 4–20 mA signal for PLCs, DCS, or machinery control units.
The 991-01-XX-01-00 MOD: 284318-01 Thrust Transmitter supports a full-scale thrust range of 0.6-0-0.6 mm and a linear Prox Out range of 0.25 to 1.65 mm. Powered by +12 to +35 Vdc, 991-01-XX-01-00 MOD: 284318-01 operates as a 2-wire device with a maximum loop resistance of 1,000 Ω at 35 Vdc and typical current limiting at 23 mA. The Prox Out signal provides a 10 kΩ output impedance calibrated for a 10 MΩ load, enabling direct diagnostic access.
Designed for DIN-rail installation, 991-01-XX-01-00 MOD: 284318-01 operates from -35°C to +85°C and supports compact installations on centrifugal compressors, pumps, motors, and fans where axial thrust monitoring is required within automated control architectures.
Applications
Axial Thrust Monitoring on Centrifugal Compressors
991-01-XX-01-00 MOD: 284318-01 is applied on centrifugal air compressors to convert axial shaft movement into a 4–20 mA signal. Using a full-scale range of 0.6-0-0.6 mm and a linear Prox Out range of 0.25 to 1.65 mm, 991-01-XX-01-00 MOD: 284318-01 allows PLCs and machinery controllers to track thrust movement and trigger control actions when preset limits are reached.
Thrust Signal Input to PLC and DCS Systems
991-01-XX-01-00 MOD: 284318-01 provides a loop-powered 4–20 mA output powered by +12 to +35 Vdc, making it suitable for direct connection to PLC and DCS analog input cards. With a maximum loop resistance of 1,000 Ω at 35 Vdc, 991-01-XX-01-00 MOD: 284318-01 supports long cable runs in automated plants.
Compact Pump and Motor Thrust Measurement
991-01-XX-01-00 MOD: 284318-01 is used on small pumps, motors, and fans where installation space is limited. The transmitter accepts a single 3300 NSv proximity probe with a 7.0 m system length, allowing axial displacement measurement without installing a separate proximitor module.
On-Line Diagnostic Signal Access
991-01-XX-01-00 MOD: 284318-01 provides a Prox Out signal through a BNC connector with a 10 kΩ output impedance. This allows technicians to connect portable analyzers for real-time thrust and gap voltage checks while the machine remains in operation.

Competitive Advantage
Integrated Signal Conditioning in a Single Device
991-01-XX-01-00 MOD: 284318-01 combines proximitor sensing and 4–20 mA signal conversion in one housing, reducing panel space and eliminating the need for external signal conditioners in automation cabinets.
Simple Loop-Powered Wiring
As a 2-wire transmitter with typical current limiting at 23 mA, 991-01-XX-01-00 MOD: 284318-01 simplifies field wiring and reduces power supply loading in control panels.
Defined Thrust Scaling for Control Logic
The fixed 0.6-0-0.6 mm full-scale option allows 991-01-XX-01-00 MOD: 284318-01 to deliver thrust signals in known engineering units, supporting direct use in control logic, alarms, and interlocks.
DIN-Rail Mounting for Fast Panel Installation
With 35 mm DIN-rail clips, 991-01-XX-01-00 MOD: 284318-01 can be mounted quickly inside automation cabinets, reducing installation time during OEM equipment assembly.
