Signal Conditioning

Signal conditioning is necessary to convert the output from a sensor into a suitable signal that can be processed or transmitted, and may include filtering, signal amplification, linearisation, or converting a signal to a particular standard analog or digital interface and protocol. Some of the typical signal conditioning options available are shown below. All signal conditioning options are fully customisable to suit each application.

RM-044

The RM-044 has been designed as a low-cost, stand-alone unit to provide signal conditioning for strain gauge type transducers such as Pressure Transducers and Load Cells. It can also be factory configured for ½ Bridge and ¼ bridge 120 ohm and 350 ohm strain gauges. Gain selection and gross offset correction and all internally link selectable. The electronics is housed in a plastic enclosure measuring 100x115x20mm. Four, 3-pin connectors are provided for signal, transducer and power connections. The RM-044 is normally supplied to provide 10 volts output for the full range of the transducer but the output will drive over the full range of ± 10 volts. The output is also configured to provide 4 to 20mA signals if required.

The RM-044 can be factory configured for many different types of sensors.

Some example configurations includes:

Differential and full bridge – for use with load cells, pressure transducers and most strain gauges
Single ended – for use with transducers with high level output (i.e. 0 – 5V, or 0 – 10V)
Single ended ratiometric – for use with ratiometric transducers (such as inclinometers)
Three and two wire quarter bridge
Half bridge strain gauge
Current input (4 – 20mA)

XTRAN Telemetry Measurement System (XTMS)

XTMS was designed to remove mining maintenance personnel from dangerous live work while facilitating accurate Wireless Measurement from a safe location and improving operational efficiency. The Industry refers to this as “Elimination of Live Work” or ELW, and has come about with a collaboration of AMA’s integration knowledge, and personnel in the industry performing the live work. XTMS sets the industry benchmark for functionality, scalability and flexibility. It's designed for many measurement locations and aims to remove the need for personnel to take manual measurements in live and potentially dangerous areas, especially during maintenance on heavy machinery and vehicles. The system can be configured with various sensor solutions such as Pressure, Linear Position, RPM, Temperature, Tilt, Vibration, Force, and more. It involves the use of wireless sensors that send measurement data via a 2.4GHz wireless platform directly to an integrated or USB wireless base station. Measurement data from each of the sensors can be viewed and logged and custom reports can be generated for predictive machine maintenance and trend analysis.
