Externally accessible, non-interactive, ±10% F.S. adjustment..Description The Dwyer Series 607 Differential Pressure Transmitter converts positive, negative (vacuum) or differential pressures of clean, dry air or other non-conductive, non-corrosive gases into a standard two wire, 4-20 mA output signal. Several factory calibrated models are available with ranges from 0-.10″ W.C. to 0-25″ W.C. All models employ a variable capacitance transducer with a micro-machined, ultra thin silicon diaphragm enabling precision measurement and control of very low pressures. Because no epoxies or other organics are used to seal the sensor, performance is exceptionally stable and drift free. It is also highly resistant to overpressure, shock and vibration.
