Dual PT100 RTD to CAN Bus Converter With Programmable CAN Bus Message Interval
Posted by on
RTD (Resistance Temperature Detectors) is a temperature sensor that contains a resistor that changes resistance value as its temperature changes. They have been used for many years to measure temperature in a laboratory and industrial process, and have developed a reputation for accuracy, repeatability, and stability.
Most RTD elements consist of a length of fine coiled wire wrapped around a ceramic or glass core. The element is usually quite fragile, so it is often placed inside a sheathed probe to protect it. The temperature sensor is made from a pure material whose resistance at various temperatures has been documented. The material has a predictable change in resistance as the temperature changes; it is this predictable change that is used to determine temperature.
SK Pang Electronics (UK) has introduced their Dual PT100 RTD to CAN Bus Converter. This is a two channel PT100 RTD to CAN-Bus converter based on the MAX31865 RTD-to-Digital integrated circuit.
