Dwyer Instruments IP-42 Current to Pressure Transducer 4-20mA Input 3-15 PSI Output

The Dwyer Instruments IP-42 is a precision current to pressure (I/P) transducer that converts a 4-20 mA input signal to a linearly proportional pneumatic output pressure of 3-15 PSI (20-100 kPa). This versatile instrument is designed for industrial control applications requiring high reliability and repeatability at an economical cost.

Key Features:

• Force balance design with coil suspended in magnetic field for accurate signal conversion
• Built-in volume booster for enhanced output capacity
• Field reversible operation (output inversely proportional to input signal)
• Flexible zero and span adjustments via front-mounted screws
• Loop-powered design requires no external power source
• NEMA 4X rated enclosure for splashdown and outdoor installation
• Intrinsically safe approval for hazardous locations
• Low air consumption at 0.03 SCFM typical

Technical Specifications:

• Input Signal: 4-20 mA
• Input Impedance: 180 ohms
• Output Range: 3-15 PSI (20-100 kPa)
• Linearity: Less than ±0.75% of span
• Repeatability: Less than 0.5% of span
• Air Supply: 18 PSIG minimum to 100 PSIG maximum, oil-free clean dry air filtered to 40 microns
• Temperature Range: -20°F to 140°F (-30°C to 60°C)
• Connections: 1/4" female NPT pressure ports, 1/2" female NPT electrical conduit
• Electrical: Two 18 AWG wire leads, 18" long (black positive, white negative)

Ideal for controlling valve actuators, pneumatic valve positioners, damper and louver actuators, relays, air cylinders, web tensioners, clutches, and brakes. The IP-42 includes a removable mounting bracket and alternate gauge ports for flexible installation configurations.
