The 991 Thrust Transmitter is designed for original equipment manufacturers (OEMs) of centrifugal air compressors, small pumps, motors, or fans, offering a simple 4 to 20 mA proportional axial displacement (thrust) signal for input to machinery control systems. This 2-wire, loop-powered device accepts input from the 3300 NSv* proximity probe and its matching extension cable, available in 5 m and 7 m system length options. The transmitter includes a Test Input pin for quick verification of loop signal output using a variable DC voltage source. Additionally, the Power-up Inhibit circuit helps eliminate signal errors caused by line voltage transients.
