WebThe first group of PTC thermistors is comprised of silistors, which use silicon as the semiconducting material. They are used as PTC temperature sensors for their linear characteristic. The second group is the switching type PTC thermistor. The switching type PTC thermistor has a highly nonlinear resistance-temperature curve. WebThermowells with stepped stems have the fastest time response because they possess the least material at the tip (smallest diameter). A small diameter also results in the least amount of drag force. Thermowells with …

WebA wake is the region of recirculating flow immediately behind a moving or stationary solid body, caused by the flow of the surrounding fluid. The alternating vortices that occur as the media flows across the shank can create turbulence causing the thermowell to resonate or oscillate. This is referred to as vortex shedding or Von Karmen trail. WebThermocouples generate a voltage directly dependent on temperature. They are particularly suited for high temperatures up to 1,700 °C (3,092 °F). Instrument designs from mineral-insulated sheathed cable are very resistant against extremely high vibration loads (depending on instrument model, sensor element and wetted materials). dhb 18 st thermotronic 2i technologieWebThermowells are essential to protecting your thermometer or temperature sensor in your high-pressure or high-temperature applications.
