When selecting a temperature sensor, please take seven key considerations in mind for selecting the best position sensor for your application 1. Measuring Method: PT100, PT1000 etc 2. Temperature Range 3. Accuracy 4. Mechanical Connection 5. Probe Length 6. Probe Diameter 7. Output Signal
How accurate is a RTD sensor (Pt100) classes A, B In China's national standard, PT100 has two accuracy classes: Class A and class B Measuring Range：-200℃～+850℃Class A accuracy（0.15+0.002*|t|）℃；Class B accuracy（0.30+0.005*|t|）℃； Note: |t| is the absolute value of actual temperature.
PT100 Temperature Sensor (RTD)Pt100 is a sensor used to measure temperature. It is one type of sensor which falls into a group called Resistance Temperature Detectors or RTD’s.
RTD Resistance temperature sensor is usually made from high purity platinum metal. Their resistance has a direct and repeatable relationship with temperature. RTD platinum temperature sensor has long term stability and strict tolerances over a wide temperature range. They are widely used in various electronic instruments, household appliance, HVAC, energy power industry and mechanical control.
