German quality product for HVAC sector, accuracy ± 1.5 % of final value. The calibrateable pressure sensors PREMASREG® 1160 are equipped with four switchable measuring ranges (four devices in one), with illuminated display, metal connection nozzles, detachable connecting terminals, and an adjustable time constant. (Attenuation of the output signal is selectable, 1 s or 10 s). These devices are used for the measurement of volume flows in air, in air conditioning and ventilation units. The K-factor can be system-specifically preset by the user within the range of 1...3000. Display and output of the unit of measurement is variably selectable, in m³/s, m³/min, m³/h, liters/s, liters/min, or liters/h, which is shown on the illuminated display, as well as an indication in case an upper or lower measuring range deviation is occurring. The piezo-resistive measuring element guarantees a high degree of reliability and accuracy. The displayed and output unit of measurement is variably selectable, in m³/s, m³/min, m³/h, liters/s, liters/min, or liters/h, which is shown on the illuminated display, as well as the switching status of the relay, and an indication in case a measuring range deviation is occurring. The volume flow measuring transducer is provided with one relay (potential-free changeover contact), e.g. for limit value control. The piezo-resistive measuring element guarantees a high degree of reliability and accuracy. Applications of these pressure sensors are in clean room, medical, and filter technology, in ventilation and air conditioning ducts, or for triggering frequency converters and ventilators. Measured media are air (non-precipitating), or gaseous, non-combustible non-aggressive media.
