Quick Detail

Description

The 991-06-70-01-05 Thrust Transmitter is designed for automated machinery applications such as centrifugal air compressors small pumps motors and fans, providing a 4 to 20 mA proportional axial displacement signal to control systems. The 991-06-70-01-05 accepts input from a 3300 NSv Proximity Probe and extension cable, with full-scale measurement of 0.6-0-0.6 mm and linear range of 0.25 to 1.65 mm (10 to 65 mils). Its 7.0 meter system length allows flexible installation while DIN-rail clips support easy mounting. Operating from -35°C to +85°C with CSA Division 2, ATEX Zone 0/2, and ABS maritime approvals, the 991-06-70-01-05 functions reliably in harsh environments. Powered by +12 to +35 VDC with maximum loop resistance of 1,000 Ω, the transmitter delivers accurate 4–20 mA output with 10 kΩ PROX OUT impedance calibrated for 10 MΩ load. Non-isolated PROX OUT and COM terminals allow dynamic vibration and gap voltage diagnostics. The 991-06-70-01-05 features potted construction for high humidity, a Power-up Inhibit circuit to prevent transient errors, and Not OK/Signal Defeat circuitry to avoid false alarms, supporting reliable automated monitoring and precise machinery protection in compact installations.
