Versatility is the key with our Series 666 Rangeable Differential Pressure Transmitter. Up to 6 field selectable pressure ranges are available in a single model. Four dipswitches located inside the transmitter case make calibration simple and easy. ABS plastic housing provides environmental protection per NEMA 4 (IP65). Units can withstand overpressure to 10 psig. Single range models are available with a digital display for local indication. Low pressure ranges and ±1% full scale accuracy make these transmitters ideal for HVAC and energy management applications.
