![]() I'm curious if its possible to use your PT100 with 44212EC sensor without major modifications and to still expect 0.1C accuracy. Regarding 3, the device features a built-in mechanism for 5-points linear calibration function, but not another more specific format 3 - tetaran If you need to use SPRT in the ~25 Ohm range, you could work from the measured resistance value (without using the internal mapping), but you will be out of the sweet spot of the device for resistance measurement and will probably loose a bit of precision Regarding 2, this device applies the resistance-to-temperature function for PT100. If you really need 0.001☌, you will probably need a more precise device, I doubt we can be as precise in absolute value. Regarding 1, the absolute precision of this device has been verified to match the requirements for Secondary SPRTs (0.03☌), but we have not checked for a higher precision. Wednesday,march 23,2016 There are 3 aspects to this question: This yocto-pt100 can be configure to measure a SPRT with constants that corresponse to ITS-90? Related articles and application examples When using the device in harsh environments for a long period of time, we strongly advise to run extensive tests before going to production. Specifications for earlier revisions may differ.Ģ The extended temperature range is defined based on components specifications and has been tested during a limited duration (1h). Suggested enclosure: YoctoBox-Long-Thick-BlackĬables and enclosures: available separatelyġ These specifications are for the current hardware revision. Supported Operating Systems: Windows (PC + IoT), Linux (Intel + ARM), macOS, AndroidĪPI / SDK / Libraries: C++ Obj-C C# VB.NET UWP Delphi Python Java Android LabVIEWĪPI / SDK / Libraries (TCP only): Javascript Node.js PHP USB isolation, dielectric strength (1 min.): 1.5kVĮxtended operating temperature 2: -30.85☌ Protection class, according to IEC 61140: class III USB cables and enclosures to be ordered separately. This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-n and to a GSM network using a YoctoHub-GSM. The probe must be purchased separately at a specialized shop. ![]() Given the number of variants of PT100 probes and their prices, the Yocto-PT100 does not include any probe. It is therefore possible to use non-insulated PT100 probes, which are often more reactive and less expensive, The Yocto-PT100 features a built-in galvanic isolation between the USB control part and the PT100 measure circuit. 3-wire probes are reasonably accurate and not too much affected by wire lengths, contrarily to 2-wire probes which are the least accurate and very sensitive to wire length. To reach the highest accuracy, a 4-wire probe should be used. The type of connection is setup in software. The Yocto-PT100 can be used with PT100 probes using 2, 3 or 4 wires. It is particularly well suited for applications such as laboratory measurements, etc. A PT100 probe is used to measure the temperature at any specific place, including in a liquid, with a very high stability and a high accuracy(sensibility up to 0.01☌ and accuracy up to 0.03☌ at 0☌ when using a PT100 conforming to IEC 60751 DIN 1/10 B standard). The module uses an external PT100 probe (not included) to make instant temperature measurements, and can also record measures on a built-in flash memory to read them later on through USB. This is the most accurate USB temperature measurement device that we offer. The Yocto-PT100 is a USB temperature sensor.
