Safetec E20.221-226 Heat Detector


The Safetec E20.221-226 heat detectors are suitable in atmospheres with high dust content or where fumes may temporarily be concentrated. The heat detectors have an open-web casing that allows air to flow freely across a thermistor which measures the air temperature every 2 seconds. The stored temperatures are then compared against pre-set values to determine whether an alarm level has been reached. There are six heat detectors to suit a wide variety of operating conditions. Static heat detectors respond only when a fixed temperature has been reached. Rate-of-rise detectors have a fixed upper limit too, but they also measure the rate to increase in temperature.
