Industrial Wireless Thermocouple High Temperature Sensor

Our long range wireless enterprise series sensors are an easy to use and reliable start to any data aggregation application. This video will demonstrate how they work, what they do, and how to use them.

Industrial Wireless Thermocouple High Temperature Sensor

NCD Industrial wireless thermocouple High Temperature sensor is capable of measuring extreme high and low temperatures.  This Industrial wireless thermocouple temperature sensor includes one XCIB-K K-Type thermocouple probe from with a 3feet cable, 20 AWG connection cable, rated for temperature measurement applications up to 1090°C (2000°F) with an accuracy of ±1.1°C. This Industrial wireless thermocouple device comes with K type connector, which can be used to connect a higher temperature range thermocouple if needed. This sensor has in built hot and cold junction to provide highly accurate reading.  This  Industrial wireless thermocouple transmitter product is an ideal product for high temperature measurements, industrial boiler temperature measurements, liquid temperature measurement, and temperature monitoring of food storage units.  This Industrial wireless thermocouple sensor product is designed to consume extremely low power and send data at extremely long distances of up to 2 miles line of light or 28 miles using high gain antennas.

Powered by just 2 AA batteries with a operational lifetime of 500,000 wireless transmissions, you can expect to achieve up to 10 years of battery life depending on environmental conditions and the transmission interval you choose.  Optionally, this sensor may be externally powered.

We opened the communications protocol so you can integrate this sensor with just about any control system or gateway you could ever want.  Send data to a PC, a Raspberry Pi, to Microsoft Azure® IoT, or Arduino.  Your data belongs to YOU and it’s up to you to decide where you want the data to arrive.  Don’t be bogged down by the limitations of proprietary cloud solutions, post the data where you need it most.  Speaking of Communications, NCD long-range wireless sensors use the DigiMesh® protocol from  DigiMesh® was designed by THE industrial leader in secure wireless communications for industrial applications.  DigiMesh® automatically hops data from gateway to gateway until it arrives at the desired destination.

There is no better IoT Long Range Wireless Termocouple Sensor on the market today.  Nothing compares with the long range, the price, the accuracy, the battery life, or the security features we have to offer.

Receiving Data From Industrial Wireless Thermocouple High Temperature Sensor

This Industrial wireless Thermocouple high temperature sensor sends data periodically, based on user-preset timing intervals.  Data transmissions include battery level, signal strength, payload, firmware version, sensor type, and device serial number.  Please see the Resources section to see detailed information on the data structure of this device. This wireless transmitter needs a receiver.  There are many options available for receiving data from NCD transmitters.  We highly recommend using our USB Modem (available during purchase) so you can monitor this device and use our LabVIEW software for changing device settings.  Using our long-range USB wireless modem, users can expect easy operation over a virtual COM port at 115.2K baud.  Optionally, we offer a Wireless receiver that operates over ethernet.  Data from NCD sensors will appear over TCP/IP on port 2101.  Simply open a TCP/IP socket, port 2101, to the IP address of the Ethernet modem and see your data stream in to your local area network.  We take software samples seriously!  Be sure to to check out the resources section of our web site to see code samples for Raspberry Pi, Visual Studio, LabVIEW, Arduino, Python, and more.

Industrial Wireless vs Long Range IoT

We realize that the Industrial Wireless line and the Long Range IoT line seem very similar and in fact are. The Industrial Wireless line has a few improvements over its counterpart in the Long Range Wireless line in form and fit, but maintain the same function.

Feature Industrial Wireless Long Range IoT
900 MHZ X X
868 MHz Option X
2-Mile Range X X

Individual Industrial Wireless lines may have a longer battery life, optional off-board sensors, more accurate readings, or many other differences that are stated on the product’s web page.


Not for use in outdoor applications or for use in excessive temperature conditions.  Prolonged freezing will prevent batteries from functioning until thawed, using extended temperature range industrial batteries may improve the useful temperature range.  Extended freezing applications should use a full-time powered solution.  Prolonged exposure to extreme humidity conditions may damage this device.  The sensing element is rated for use for 5 years and may be replaced.  Exposure to high temperatures may cause the batteries to leak, causing permanent damage to this device.  NCD Warranty does not cover battery corrosion or use in excessively smoky environments under any circumstances.

We Customize Just for You!!

NCD offers many custom IoT electronic design services to help tailor our product to your exact needs.  Whether you are looking for custom firmware, circuit board modifications, metal enclosures, or industrial color printing, we can help you with a wide variety of design services.

Custom IoT Electronic Design Services Process

Most of our users purchase off-the-shelf hardware for initial testing.  Once everything is working, they contact us to build a custom solution which may include specialized changes to the board, firmware, connectors, etc.  Custom boards have many advantages such as reduced wiring, easy installation, small size, less power consumption, and in some cases, an overall reduction in product cost.  Custom IoT Electronic Design Services will have your company name and logo on the board as well as the enclosure.

Customized IoT Electronics

NCD engineers can help build a customized solution for your particular application based on the designs you see on our website.  We can combine devices onto a single board, change the shape, or even some of the components to meet your exact needs.  We also provide turn-key metal enclosures with powder coating and full-color printing on the top side starting at just $500 for setup!  We have more than 20 years of experience in electronics design and manufacturing.  All of our products are designed and manufactured in the USA, so we are here to support the products we make.  We only ask that our customers prototype their needs using our existing products before we customize.

Customization Guidelines

  • Custom designs should be based on our existing product because we can’t build rockets or electric cars over here!
  • We do not provide customization services if it involves the introduction of a new or untested technology.
  • Custom engineering fees depend on your requirements, so please contact us for a quote!
  • We maintain ownership of all designs, including our customized designs as they are based on our existing Design.
  • We will only ship the customized product to you or your authorized agents.
  • We have an NDA available if needed.
  • The turn-around time is about 2-3 weeks.
  • We specialize in low-volume designs, no quantity is too small!
  • We have the ability to scale to large volumes as needed.

Getting Started with Product Customization

All you have to do is contact us and we will walk you through the process from beginning to end, based on your individual needs.  Some people are surprised at how fast we finish CAD design (usually a few hours), but keep in mind, we still have to build your design, which takes considerably more time.  When we customize product, here are the general services we provide:

  • We design the circuit board.
  • We communicate with our customers throughout the customization and manufacturing process.
  • We manufacture surface mount stencils and circuit boards.
  • We program our pick and place machines to build your boards.
  • We build a working sample and run it through our wave solder machine.
  • We test your custom IoT solution.
  • Once the design is finalized it won’t be possible to make changes during production (changes cost money and require us to repeat the above processes)
  • Once it meets all your requirements, we will start production as needed.
  • We work with our metal fabricators to design a metal enclosure if required.
  • You work with our artist to print the top side of the enclosure in full color with your company logo if required. and ControlEverything Site Migration Notes
