Series WWDP Wet-to-Wet Differential Pressure Transducers
Description: The Series WWDP Wet-to-Wet Differential Pressure Transducer offers exceptional versatility with 30 field-selectable variations across just three models. With configurable unidirectional and bidirectional pressure ranges, along with selectable 0-5, 1-5, 0-10 VDC, and 4 to 20 mA output options, the WWDP caters to diverse application needs. It features auto-zero capability and a field-selectable port swap function, eliminating the need for costly replumbing in case of improper installation or transducer replacement. An optional LCD display provides on-site indication of line and differential pressure. Housed in a rugged, all-cast aluminum enclosure rated NEMA 4 (IP66), the WWDP is suitable for measuring liquid and gas flow, pressure drop across filters, liquid level or pressurized vessel measurement, and integration into energy management and process control systems.
Specifications:
- Service: Gases or liquids compatible with 17-4 PH stainless steel.
- Accuracy: All pressure ranges have ±1% full-scale accuracy, except the lowest selectable range of each unit, which is ±2% full scale.
- Stability: ±0.5% per year.
- Temperature Limits: Compensated Temperature Range: 32 to 130˚F (0 to 54˚C); Operating Temperature Range: -4 to 185˚F (-20 to 85˚C).
- Pressure Limits: Max working pressure: WWDP-1: 50 PSI; WWDP-2: 100 PSI; WWDP-3: 250 PSI; Proof Pressure: 2.2X of full scale; Burst Pressure: 40X of full scale.
- Thermal Effect: 2% FS/100˚F (50˚C) includes zero and span.
- Power Requirements: 12 to 30 VDC/18 to 28 VAC (Reverse Excitation Protected). Note: 4-20 mA output cannot be powered with AC voltage.
- Output Signal: Selectable 0-5, 0-10 and 1-5 VDC; 4 to 20 mA.
- Zero & Span: Digital “re” zero button (should be used when changing ranges). Span can be adjusted by changing between field selectable ranges.
- Response Time: 1 to 5 sec (selectable).
- Loop Resistance: 1000 ohms.
- Current Consumption: VDC power: 0-5, 1-5 VDC output 4 mA (typ); 0-10 VDC output 5 mA (typ); 4-20 mA output 20 mA max. Current Consumption will equal the transmitter output in current mode. VAC power: 0-5, 1-5, 0-10 VDC output 40 mA (typ).
- Electrical Connections: 1/2” Conduit.
- Process Connections: 1/8” Female NPT Internal.
- Enclosure Rating: Designed to meet NEMA 4 (IP66).
- Mounting Orientation: Vertical; Mount the pressure ports down (keeps debris from building up inside the pressure port).
- Size: 4 x 6 x 2 in (102 x 152 x 51 mm).
- Weight: 1.5 lb (680.4 gm).
- Agency Approvals: CE.
The Series WWDP Wet-to-Wet Differential Pressure Transducer offers extensive configurability and robust performance, making it an ideal solution for various industrial pressure measurement applications. Its wide range of features and durable construction ensure accurate and reliable operation in challenging environments.
