WebRate-of-Rise Thermal Detectors measure the rate at which the air temperature changes during a fire event. Measuring the change in temperature provides a faster alarm response than measuring the temperature level in a space. The rate-of-rise detector measures the change in the temperature of the space through the use of a differential pressure ...
WebNov 25, 2024 · A sweeper or recoater roller moves across the surface, picks up excess material from the reservoir and deposits new and colder powder on top of the build platform to create the next layer. Again, the powder is heated to keep it at the build temperature.
