Robert Owen Produces Serial Sensor Signal Conditioning products. So if converting between a sensor & serial connection is needed, we can offer the devices to help you simplify your environmental monitoring requirement.

Options in Serial Sensor Signal Conditioning

ROI-USB-Thermistor NTC thermistor temperature sensor monitoring system
ROI-USB-Thermistor NTC thermistor temperature sensor monitoring system

NTC Thermistor to USB sensor converters, used when you have a spare USB serial port on your PC or laptop and need to read temperature. So you can use just plug into it, connect the sensors, and take sensor readings*.

4-20mA to USB sensor converters, used when you have a spare USB serial port on your PC or laptop and need to monitor a 4-20mA sensor transmitter. So you can use just plug it in, connect the transmitter (transmitter power not provided) and take sensor readings*.

0-5Vdc USB sensor converters, used when you have a spare USB serial port on your PC or laptop and need to monitor a 0-5Vdc output sensor signal conditioner. So you can use just plug it in, connect the signal conditioner (signal conditioner power not provided) and take sensor readings*.

* USB converter monitors when used with compatible software.

We provide serial signal conditioning for resistive sensors such as Thermistor temperature sensors, or Potentiometer position sensors. Because they are USB compatible sensor converters, you plug and play. So they will save you time and money.

Learn more about our serial signal conditioners

We know serial sensor signal conditioners are a simple solution, when you have a spare USB port on your PC. So the conditioner output is the same as a spare input, then use that channel to measure an NTC Thermistor temperature sensor or 4-20mA transmitter with it.

USB signal conditioners are simple to use

Because there are only 2 wires to connect for the input and 2 wires to connect for the output, the 4-20mA transmitter is very simple to use with a USB signal conditioner. So simple to use. You will add a 4-20mA sensor transmitter to a spare USB input on your PC in no time. So we show, in the image below, 4-20mA transmitters wired to a USB converter in the example diagram below.

Robert Owen offers you a variety of serial sensor conditioning products.

USB Sensor Converters

When serial sensor conditioners with USB connection are what you need, we offer USB converters for both NTC Thermistor temperature sensors , 4-20mA transmitters, or voltage signal conditioners.
