Specialists in thermistor analog converter digital signal conditioner and thermistor analog signal 4 20ma transmitter signal conditioner devices. 

With our ROI-XMA, ROI-USB, & ROI-ISOV products; we offer the components necessary to make thermistor measurement simple. DIN rail and surface mounted packages. Many ranges from our standard products are possible, as well as customized solutions.

The ROI-USB thermistor analog conversion digital usb adapter units allow standard ntc thermistor or ptc thermistor 10K thermistors to be used to measure temperature with a Windows XP PC via USB 2.0 ports. Multizone temperature measurement or temperature profile recording is simple. PC powered, no external supply needed; just connect the sensors to the thermistor USB adapter and connect it to the PC.

The ROI-XMA thermistor analog signal 4 20ma transmitter units allow a variety of standard bare bead or probe thermistor sensors to be connected to a vairety of industrial plc's, data loggers, or analog conversion digital PC devices to be used to measure temperature.

The ROI-ISOV galvanic isolator signal conditioner amplifiers can be used in applications where analog signal noise requires a ground loop isolator for noise suppression or ground loop elimination.
