The 985A differential pressure transmitter measures non-aggressive air pressures in applications such as building automation and clean rooms. It is a 3-wire device with piezoresistive sensing, configurable output signals of 0...10 V or 4...20 mA, and automated zero drift compensation. Two pressure ranges are selectable via jumper, including -100...+100 Pa up to 0...2.5 kPa. Response time is 0.1 s or 1 s, with operating temperature from 0 to 50°C. Supply voltage is 18...30 VAC/VDC. Housing is ABS, dimensions are approximately 81 x 83 x 41 mm, and weight is approximately 125 g. Accuracy is ±1% of full scale with ±1.5% temperature error. It meets IP65 and EN 61326 standards.
