For precision temperature sensing, nothing beats a PT1000-S Waterproof 1m 30mm Stainless Steel Pole Probe Temperature Sensor. Resistance temperature detectors (RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes, basically a kind of thermistor.In this sensor, the resistor is actually a small strip of Platinum with a resistance of 1000 ohms at 0C, thus the name PT1000. Compared to most NTC/PTC thermistors, the PT type of RTD is much most stable and precise (but also more expensive). PT1000s is useful to measure temperature in laboratory and industrial processes; and have developed a reputation for accuracy (better than thermocouples), repeatability, and stability.This high-temperaturePT1000 sensor is equipped with a 316L stainless steel shield (try saying that five times fast!) that is good for up to 550C.How does the sensor work?As the temperature in your application changes then the electrical resistance will also change. An increase in temperature will increase the resistance of the temperature sensor.The measurement is completed by your instrument by applying a small measurement voltage and utilizing a bridge type circuit.Features:-Based on resistance measurement principles.Resistor material is Platinum with a value of 1000 ohm at temperature 0C.Platinum has a positive resistance-temperature factor; resistance increases with rising temperature.Resistance variation is a function of temperature: 3.85/C nominal.High accuracy and stability compared to thermocouples, silicon-based temperature sensors, or thermistors.specifications;-Temperature Range(C) -200 to 420 Probe Material Stainless Steel Probe Diameter(mm) 4 Probe Length(mm) 30 Cable Length 1.05 Meter Accuracy (0.3C 0.5%|t|) Response Time(s) <0.5*product image for illustration purposes only. actual product may vary.
