Pressure sensors - Import export

The device can perform water pressure measurements in the water supply network and temperature measurement in 2 places - on the sensor itself and in the device housing. The sensor is produced in two versions - IP54 (possible replacement of the battery on the user's side on the object) or IP68 (battery replacement only in the manufacturer's service) The sensor measures at intervals of 1 min to detect sudden pressure increases. It is possible to set an alarm threshold, the exceeding of which triggers the immediate sending of data frames. In normal operation mode, reading reporting takes place with an interval of 15 minutes every 6 hours from the last 24 hours.

The heaters are standard equipped with an electronic control module that maintains the temperature set by means of a potentiometer located on the front panel of the heater. The element that activates the electric heaters is a triac, thanks to which the heaters are always turned on when the current reaches zero. The safety of the heater is ensured by three protections, an electronic module controlled by a temperature sensor, a pressure sensor that turns off the heaters if there is no air flow in the duct and a thermocouple turns off the heaters when the temperature rises above 75°C
