Supported Applications
The Dwyer Series IWP Industrial Weatherproof Pressure Transmitter is designed for pressure measurement in industrial conditions requiring high-performance, stability, and long service life. The transmitter delivers a precise operation under dirty and wet conditions, making it an ideal choice for petroleum, chemical, and metallurgical industry applications.
Operating Conditions & Performance
The Series IWP measures gases and liquids compatible with 304 and 316 stainless steel wetted materials. The transmitter provides a measurement accuracy of 0.5% FS with stability less than 0.2% FS per year. A temperature coefficient of 0.3% F.S. per 10°C is specified.
Operating conditions are defined by the following limits:
- Temperature Limits (Process): -22 to 203°F (-30 to 95°C)
- Compensated Temperature Limits (Ambient): 32 to 158°F (0 to 70°C)
- Pressure Limits: 1.5 x pressure range
- Enclosure Rating: IP65
The unit operates on a power supply of 12-36 VDC and provides an output signal of 4-20 mA with a maximum loop resistance of 1200 Ω.
Configuration Options
The Series IWP is offered in multiple pressure ranges to accommodate specific process requirements. Available measurement ranges include:
- 30 psig (Model suffix -00)
- 50 psig (Model suffix -01)
- 100 psig (Model suffix -02)
- 200 psig (Model suffix -03)
- 300 psig (Model suffix -04)
- 500 psig (Model suffix -05)
- 30 psia (Model suffix -10)
The transmitter features a durable cast-aluminum shell with 1/2" female NPT connections for both the process and electrical conduit entry. A 4-digit LED display allows for field inspection of pressure in psi units.
