iT150 Series Vibration Transmitters Installation and Operating Manual

2020-10-30

This document contains information on the installation and operation of the iT150 Series of Vibration Transmitters. The transmitters are designed and manufactured in the USA by Wilcoxon Sensing Technologies, Frederick, Maryland.
The iT150 vibration transmitter performs acquisition and processing of dynamic vibration signals.The transmitter accepts vibration signals from piezoelectric (IEPE-type) accelerometers, piezovelocity transducers (PVT™) and other sensors with comparable electrical characteristics. The iT150 also features an input for connection to a Model 786T-type (or compatible) temperature sensor.
The transmitter conditions, digitizes and processes the input signal using powerful DSP technology. All filtering, frequency selection, sub-sampling and power detection is performed digitally, for consistent, reliable results. The vibration measurement result is then scaled and converted to a 4-20 mA analog output. A temperature measurement result is also available as a separate current loop output.
The transmitters are factory-configured, allowing for quick and easy field deployment. There are no hardware jumpers or switches to set. User-specified parameters include: input signal type, detector type, output type, English or metric units, 4-20 mA full-scale range and measurement bandwidth.
The iT150 is housed in a durable plastic enclosure with a 35mm DIN rail mount. A convenient, front-panel BNC connector allows monitoring of the buffered sensor output. LEDs provide at-a-glance operational status and indicate when power, sensor and 4-20 mA loops are correctly connected to the transmitter and working properly. Removable, uniquely-keyed terminal blocks allow for easy wiring and ensure correct terminal block installation into the various module IO ports.
