Dwyer 682-3 : Industrial Pressure Transmitter, Range 0 to 250 psi (500 psi overpressure), ±0.13% Full-Scale Accuracy, 4-20 mA Output, NEMA 4 (IP65)
The Dwyer Series 682 Industrial Pressure Transmitter is built to withstand harsh environmental conditions, including shock, vibration, extreme temperatures, and EMI/RFI interference. Encased in a welded stainless steel housing that meets NEMA 4 (IP65) standards, it reliably measures gauge pressure and delivers proportional 4-20 mA analog outputs. Compatible with gases and liquids suitable for 17-4 PH stainless steel, it operates in temperatures from -40° to +260°F (-40° to +127°C). Features include atmospheric venting through its cable for accuracy, standard pressure fittings, and minimal zero shifts.
Features & Benefits
- Weatherproof Design: The welded housing protects the device from harsh outdoor and industrial environments.
- Environmental Resilience: Unaffected by temperature fluctuations, shock, vibration, and EMI/RFI, ensuring dependable equipment operation.
- Easy Calibration: External span and zero adjustments streamline installation and reduce maintenance time.
