Riverhawk’s Indikon XT Series Transmitters Overview

XT Series TransmittersThe XT-101 Vibration Transmitter converts the vibration signal as sensed by a proximity probe or seismic senor to a DC voltage which proportionally controls a 4-20 mA current loop for a specified vibration range such as 0-5 mils peak-to-peak, 0-125 microns peak-to-peak. Please take note that the loop current solely powers the transmitter. The XT-101 Model is most commonly used. XT-101X and XT-101Y Models are only used in applications where two probes are mounted in close proximity of each other. The XT-101X and the XT-101Y versions have different excitation frequencies to prevent interference

Riverhawk’s Indikon XT-103 Transmitter Overview

The XT-103 Displacement Transmitter connects to a proximity probe that is mounted perpendicular to a metal target. The transmitter generates DC voltage that is proportionate to the gap between the probe and the metal target. This DC voltage controls a 4-20 mA current loop for a specified probe gap range such as 35 – 75 mils, 20 – 200 mils, 0.50 – 2.00 mm. Please note that the loop current solely powers the transmitter.

Riverhawk’s Indikon XT-121 Transmitter Overview

The two-wire XT-121 Vibration Transmitter converts the vibration signal as sensed by an accelerometer to a DC voltage which proportionally controls a 4-20mA current loop. The 4-20mA range equals a vibration range in g’s (peak or average) of 0-1, 0-3, 0-5, etc. or in m/s² (peak or average) of 0-10, 0-20, 0-30, etc. The accelerometer signal first passes through a band-pass filter to establish the frequency range of interest. To monitor bearing vibration, ranges are most often expressed in velocity units (inches or mm per second, peak, or average) rather than acceleration units in g’s or m/s². Units with velocity outputs, XT-121V, have a signal intergrator that follows the band-pass filter. The vibration ranges become then 0-0.5ips, 0-1ips, 0-10mm/s, 0-15mm/s, etc. The transmitter is powered solely by the current loop
