DS1-010 and DS1-420 series pressure transmitters are suitable for air and non-corrosive gases. They measure differential and opposite pressures, relative pressures, and optionally flow rates. Analog output signals are 0-10 V or 4-20 mA or 0-10 kHz. The 4-20 mA pressure transmitter is realized with two wire system technology. For velocity measurements, you can sort the square root output. DS1 achieves high reliability and accuracy due to piezoresistive cell. The installation position has little dependence on the zero signal. Resistance to overpressure is higher than using other physical principles. The transmitter is packaged in sturdy aluminum. This ensures good EMC characteristics. The DS1 has optional electronic signal dampers and is powered at 24VAC or 230 VAC.
