Quick Detail

Description

The 990-05-70-03-00 Vibration Transmitter is a precision, loop-powered industrial vibration monitoring device designed for automated machinery protection systems. Compatible with a single 3300 NSv Proximity Probe and extension cable, this transmitter converts non-contacting displacement measurements into a 4 to 20 mA proportional vibration signal, providing real-time input for control and safety logic in industrial automation. Its compact design (9.8 x 7.3 x 5.8 cm, 0.5 kg) and versatile mounting options using DIN clips or screws make it suitable for centrifugal air compressors, small pumps, motors, and fans where installation space is limited. The transmitter operates across -35°C to +85°C, with storage up to -52°C to +100°C, and supports a full-scale vibration range of 0–5 mils peak-to-peak (0–125 μm) with linear Prox Out from 0.25 to 1.65 mm (10–65 mils). Non-interacting zero and span potentiometers allow easy loop adjustment, while integrated Proximitor circuitry eliminates the need for external signal conditioning units. Additional features include coaxial diagnostic output, Not OK/Signal Defeat circuit for false alarm prevention, and potted construction for 100% condensing humidity resistance. The 990 Vibration Transmitter is ideal for OEMs seeking a compact, reliable, and precise vibration input for automated control systems.

Applications
