Dwyer 616W-6-LCD is a highly accurate differential pressure transmitter with a temperature range of -4 to 158°F (-20 to 70°C). It features ±0.25% FS accuracy at 77°F (25°C) and a display accuracy of ±0.5%. It operates on 10 to 36 VDC or isolated 21.6 to 33 VAC power source. The transmitter provides an output signal of 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC. It is suitable for air and non-combustible gases. The transmitter has a NEMA 4X enclosure rating, allowing it to be used in various environments. Installation and calibration is made easy with digital push-button zero and span adjustments. The unit can be mounted in any orientation and has a response time of either instantaneous or 3 seconds, selectable by the user. Its electrical connections use a 4-wire removable European style terminal block, accommodating wire gauges 16 to 26 AWG. The wetted material and pressure limits vary based on the model chosen. The 616W-6-LCD offers stable and reliable performance throughout the years with ±1% FS/yr stability. Its thermal effect is ±0.02% FS/°F (±0.036% FS/°C) and loop resistance ranges from 0-1250 Ω for current output and minimum load resistance of 1 kΩ for voltage output. With a maximum current consumption of 21 mA, this differential pressure transmitter is a versatile and dependable choice for pressure monitoring applications.
