THE ROI-USB/Thermistor/UCONServer Bundle 

TEMPERATURE DATA ACQUISITION SOLUTION

With the ROI-USB A-D and UCONServer OPC Communication Software, you can add sensor data to customizable OPC compatible HMI programs.

ROI-USB A-D's allow you to measure thermistors, potentiometers, pressure switches, resistive sensors, contact closures, dc voltage signals, and mA current signals; without external converters or power supplies. The ROI-USB is designed to work directly with your desktop or laptop PC.

ROI-N10K-CP NTC 10K Copper Probe Thermistor

16" PVC-insulated wires with tinned ends

The ROI-N10K-CP 10K ohm NTC thermistor series allows connection to your USB thermistor measurement system with a simple screw driver. The connection lead can be extended in the field as needed using 2 wire copper cable and many standard electrical connectors. No need for special alloy extension cables or hard to get multi wire cables.

The thermistor is a simple to connect device, without the need to worry about misconnection. Unlike other polarity sensitive sensors, like the thermocouple or the RTD, the thermistor may be connected with either lead attached to either input screw.
