Industrial Dual 0-20mA and PTC Bricklet

With the Industrial Dual 0-20mA Bricklet and the PTC Bricklet there are now two new products available in our shop. Both Bricklets are available for an introductory price of 16.99€ until July 21st.

The Industrial Dual 0-20mA Bricklet can be used to read out sensors that are not based on voltage but on current. If voltage is used for measuring, there is always voltage drop (depending on wire length etc) that can distort the measurment. Problems of this kind can not occur if current is measured. This kind of sensor interface is typically used in an industrial environment. It is standardized under IEC 60381-1. The Bricklet can read out up to two sensors at the same time. It has a high accuracy (0.15%), resolution (up to 0.172µA) and sample rate (up to 240 samples per second).

With the PTC Bricklet we provide the possibility to read out Pt100 and Pt1000 temperature sensors. Those are so called PTC thermistors, i.e. temperature-sensitive resistors. The sensors are available in different types (accuracy classes, 2-, 3- and 4-wire) and for different purposes. Often it is used to measure very low or high temperatures or in the food sector. It is not easy to read out Pt100 or Pt1000 sensors with a high accuracy. We use an IC that is specifically made for this purpose. It has a resolution of 15bit (0.03125°C) and a accuracy of 0.5% on the full measurement scale (-246°C to 849°C). We support 2-,3- and 4-wire type. This allows to chose the correct sensor for a specific use case, the PTC Bricklet supports all Pt100 and Pt1000 sensors.
