PT100MK1 Yocto PT100 sensor


Small device to measure the temperature with very high precision, using a PT100 temperature sensor (2, 3 or 4-wires supported). The device includes a built-in data logger to record measurements. The PT100 connection is electrically isolated from the USB bus.

SKU: PT100MK1 Categories: ,


The Yocto PT100 sensor is a Swiss-made USB temperature sensor. This is the most precise USB temperature measurement device that we offer. 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. 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 precision (sensibility up to 0.01°C and precision up to 0.03°C at 0°C when using a PT100 conforming to IEC 60751 DIN 1/10 B standard). It is particularly well suited for applications such as laboratory measurements, etc.

The Yocto-PT100 can be used with PT100 probes using 2, 3 or 4 wires. The type of connection is setup in software. To reach the highest precision, a 4-wires probe should be used. 3-wires probes are reasonably precise and not too much affected by wire lengths, contrarily to 2-wires probes which are the least precise and very sensitive to wire length.

The Yocto PT100 features a built-in galvanic isolation between the USB control part and the PT100 measure circuit. It is therefore possible to use non-isolated PT100 probes, which are often more reactive and less expensive,

Given the number of variants of PT100 probes and their price, the Yocto PT100 does not include any probe. The probe must be purchased separately at a specialized shop.

This device can be connected directly to an Ethernet network using a YoctoHub Ethernet, to a WiFi network using a YoctoHub Wireless-g, it can even be connected to a GSM network thanks to the YoctoHub GSM.

USB cables and enclosure to be ordered separately from PT100MK1 Yocto PT100 sensor.
