Robert Owen Produces Analog Sensor Signal Conditioning products. So if converting between sensor & signal type is needed, we can offer the devices to help you simplify your environmental monitoring requirement.
We provide analog signal conditioning for resistive sensors such as Thermistor temperature sensors. Because they are PLC compatible 4-20mA sensor transmitters, they will save you time and money.
About analog signal conditioners
Temperature Sensor Signal Conditioners are a simple solution, when you have a spare 4-20mA, or 5/10Vdc analog channel on your PLC. Because the conditioner output is the same as your spare input, you, can use that channel to measure an NTC Thermistor temperature sensor with it.
Position Sensor Signal Conditioners are a simple solution, when you have a spare 4-20mA, or 5/10Vdc analog channel on your PLC. Because the conditioner output is the same as your spare input, you can use that channel to measure a Potentiometer position sensor with it.
Analog 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. So simple to use, you will add a sensor to a spare analog input on your PLC in no time. So for easy understanding, see how 4-20mA transmitters are wired in the example diagram below.
So Robert Owen offers you a variety of analog sensor conditioning products.
Temperature Sensor Signal Conditioning
When temperature sensor conditioning by 4-20mA transmitters are what you need. So we offer transmitters for NTC Thermistor temperature sensors.
| Thermistor |
| -10 to 50C 10K NTC / 4-20mA |
| 0 to 50C 10K NTC / 4-20mA |
| -10 to 75C 10K NTC / 4-20mA |
| 0 to 75C 10K NTC / 4-20mA |

*** Mated connector adds additional 3/8” to height.
Because many PLCs have spare 4-20mA inputs for sensor measurement, with the ROI-XMA sensor transmitter you can read temperature or position with them. The ROI-XMA transmitters allow the simple measurement of industry standard NTC thermistors. In other words, existing NTC thermistors can be connected to modern control systems. Because the ROI-XMA sensor transmitter is a simple way to add sensor measurement to a PLC. So useful in HVAC systems, refrigeration systems, chillers, environmental monitoring, computer room monitoring, dryer, and other industrial applications.
Robert Owen has years of experience in connecting sensors and software together. Because we code custom software solutions, we can get it done. We offer the approach most suited to the project. We can get it done, regardless of size, because we have the pieces to build solutions. For monitoring anywhere from a single sensor to hundreds. Robert Owen can assist with Sensor Signal Conditioning, Sensor Signal Processing, and Sensor Data Acquisition. Parts in a range of sensor signal connection services we offer.
