Sensor signal conditioning trend recordingROI products are designed with system compatibility in mind. ROI-USB, ROI-XMA, & ROI-ISOV combined as integrated packages, are standard not special. The various series of ROI devices are each building blocks, that may be used as expansion or retrofit components; to enhance the capabilities of many existing systems. Robert Owen Inc.'s transmitters are easily connected to: data acquisition devices (such as PC A-D's) or controllers (such as PLC's). A typical example of this is; an existing PLC system or RTU, where a 4-20mA channel is available, but a requirement is added for an additional measurement of temperature. The ROI-XMA RTD or Thermistor transmitters allow the conversion of a temperature sensor to 4-20mA, providing signal capability with the existing 4-20mA channel. This can help eliminate potential difficulties faced, when system expansion may not be done without great difficulty. Some examples of expansion difficulty are: limited space, limited device expansion capability, the high cost or lack of availability of direct sensor measurement cards for the PLC or RTU, excessive distance between the PLC or RTU & the sensor, etc. Using the right signal conditioner, expanded capabilities can be added to an existing, eliminating these difficulties.
Beyond this, the component ROI devices are by design signal compatible with each other. In applications where a PC is available, but the need arrives for a mixed signal monitoring system; a combination of ROI devices can be used together to form combined systems. Robert Owen Inc., produces; USB analog to digital converters, Windows XP PC compatible, USB sensor signal adapters; for real time sensor data acquisition of voltage, current, and resistance based sensors; the ROI-USB. Useful for measurement of resistive temperature sensors, such as thermistors (2252 ohm and 10k ohm) and RTDs (PT1000, 1000 ohm platinum), 4-20ma transmitters (temperature transmitters, such as thermistor transmitters and RTD transmitters), power transmitters (when used with galvanic isolators), etc. The ROI-USB can be an integral part of mixed sensor signal conditioner systems. Robert Owen Inc.'s analog USB adapters (or USB A-D's) measure voltage, current, and resistance; when the right signal conditioning is used. Recording instruments, such as the ROI-USB A-D, can be used to monitor a range of sensors and signals; to read temperature sensors (such as the RTDs and the Thermistors), position and level sensors (such as potentiometers), or power (through the use of: voltage isolators, voltage dividers, & shunt resistors as necessary). By using current transmitters (such as ROI-XMA 4-20mA transmitters) or isolation amplifiers (such as ROI-ISOV) as signal conditioners (instrumentation amplifiers for sensor signal conditioning), sensor signals can to be instrumented for real time monitoring or data acquisition. With software tools like OPC Servers and DDE Servers; turn Excel into a real time display and data acquisition program. Compatible software tools, to turn the USB A-D's into Data Acquisition Systems. Excel temperature measurement allows Temperature Recorders, Temperature Profile monitoring, USB Thermometer, and a variety of other instrumentation applications are possible. | |||||
