The Best Thermocouple Card For Downhole Temperature Monitoring

We are proud to officially announce the all new GEOXTR 18pt Thermocouple Input Card!

A New Standard For Quality

Born out of a need for higher-quality data, industry-specific capability, and far superior long-length thermocouple performance, the GEOXTR-18 has been designed to operate in a class of its own. Setting a new standard for quality and capability, the GEOXTR-18 provides unprecedented value for downhole temperature monitoring for oil & gas and geothermal customers.

Industry Focused Features

Our team has designed the GEOXTR 18pt Thermocouple Input Card from the ground up to be a go-to solution for users requiring a reliable product with an industrial focus. It features advanced capability, a Class 1 Div 2 certification, direct RS485 Modbus output, unmatched performance at long lengths, and the ability to operate reliably in extreme conditions including, temperatures from -40°C to 85°C. This thermocouple input card delivers on the capability and feature set that users in the energy industry require.

With 18 unique channels integrated into a single card, the GEOXTR-18 ensures a simple and cost-effective thermocouple input solution for users monitoring multiple data points.

Premium components and a clever industry-focused design provides users with the highest quality data possible.

Resolution: 0.001°C
Accuracy: 0.1°C

With an industry-leading impedance of >1.2 MOhm the GEOXTR-18 maintains temperature accuracy at lengths suitable for downhole oil & gas applications. Where many cards drift at lengths above 1,000m, our card has been proven to be upwards of 20°C more accurate at lengths exceeding 4,000m.

Designed to work in the hazardous environments found in different industrial environments such as upstream oil & gas, our GEOXTR-18 features a Class 1 Div 2 Groups CD T4 certification.

Our GEOXTR-18 comes ready to work out of the box. While it doesn’t require any on-site calibration, for users looking to monitor performance or take further control of configuration our intuitive GEOXTR Viewer software is included.

Designed to work with Type J, K, E, N, R, S, T, & B thermocouples, our GEOXTR-18 is designed to integrate into any number of temperature monitoring applications.

A slim compact design and integrated DIN Rail mount makes this easy to integrate into any data acquisition setup.

Gone are the days of removing daily or seasonal temperature swings from your data! With an optimized internal design and highly accurate integrated cold-junction measurement, the GEOXTR-18 is able to accurately compensate for ambient temperatures.

Convenient RS485 Output makes for easy integration into any SCADA system. The universal compatibility ensures all users can easily take advantage of their data.

Class-Leading Capability For Downhole Users

Oil & Gas and Geothermal users have traditionally had to accept significant error in their downhole thermocouple readings. This has produced a lack of confidence in data readings when temperature values can be off by over 20°C!

With the significant investment in deploying multi-point thermocouple bundles downhole we feel this level of data inaccuracy is unacceptable. When you have invested potentially hundreds of thousands of dollars in downhole temperature monitoring equipment, shouldn’t your surface input card be able to accurately tell you what the downhole temperatures are?

We believe it should. That is why we have developed the GEOXTR-18, to address these issues and provide accurate & stable data readings for users depending on downhole temperature readings to better optimize and understand their production environment.

Best-In-Class Resolution

With a best-in-class data resolution of 0.001°C, the GEOXTR-18 provides a more accurate picture of temperature fluctuation. As you can see in the graph below when connected to the same thermocouple point the GEOXTR-18 reveals a level of detail far exceeding that of the competing 8pt thermocouple input card. For users demanding the most from their temperature measurement equipment, or those optimizing industrial production off of real-time data, the GEOXTR-18 is the easy choice.

Superior Long-Length Accuracy

The GEOXTR-18 was designed with the intent of being a first-of-its-kind solution for long-length thermocouple monitoring. Especially in applications such as downhole oil & gas, long-length data accuracy is critical. The current 8pt card commonly used in the industry can present data errors of over 20°C at lengths of 4000m. This is unacceptable for downhole use or other industrial applications where accuracy is essential for optimization. The GEOXTR-18 maintains its leading accuracy at long lengths presenting data well within the margin of error of any thermocouple.

Superior Long-Length Data Stability

Not only does the GEOXTR-18 provide accurate data at long lengths, but it also maintains data stability which we have thoroughly tested at lengths up to 4,000m (as shown below). The current leading 8pt thermocouple card not only provides data which is off by over 20°C (over 13%), but it is also wildly unstable with a significant number of points spiking and dipping well outside of an acceptable range. This not only presents a major challenge for engineers and automation systems but also destroys confidence in overall readout performance. The GEOXTR-18 however provides accurate, stable, and reliable data you can trust.

Universal Compatibility

Born out of a need for superior thermocouple accuracy at long lengths in oil & gas applications, and designed to be applicable for industrial use around the globe, the GEOXTR-18 features universal compatibility. Designed to work with Type J, K, E, N, R, S, T, & B thermocouples, and featuring RS485 output and direct DIN Rail mounting capability it has been designed to work anywhere, in even the most challenging conditions.

Easy Configuration

Through the use of our intuitive GEOXTR Viewer software customers can easily access a full suite of configuration parameters including the ability to establish communication, log data, and update firmware. This custom software package comes with every GEOXTR-18 and requires a common RS486 to USB cable (not included). And with convenient LEDs on the top of the case users in the field can quickly troubleshoot and verify functionality.

The Best Thermocouple Card For Downhole

The accuracy, low impedance, and overall performance makes the GEOXTR-18 one of the best thermocouple input cards out there.

However, given the unique requirements for downhole applications and their need for long-length performance, our input card is the logical choice. Especially when compared to the many limitations of the other cards commonly used in our industry.
