  • Simple 3-wire 0.5–4.5 V DC output on 5 V supply

Johnson Controls P499 Pressure Transducer

The Johnson Controls P499RCP-105K is a pressure transducer built for pressure washer systems. It measures from 0 to 500 psi and outputs a 0.5 to 4.5V DC signal. The stainless steel housing carries an IP67 rating. It suits installers and service technicians fitting or replacing sensors on compatible equipment.

SAE 45° Flare Process Connection

The transducer uses a male 1/4 inch SAE 45 degree flare process connection. This specific thread and sealing geometry decides whether the part fits the existing port. A mismatched connection type will prevent installation or cause leaks. Verify the port specification before ordering.

Stable Output Across Temperature Extremes

The sensor maintains its stated accuracy of +/-1 percent of full scale from -40 to 185 degrees F. The 5V DC supply requirement and three-wire Packard connector remain consistent through this range. Output drift stays within tolerance during prolonged exposure to temperature cycling.

Questions about this item

What does the 0.5 to 4.5 V DC output range mean when the transducer is installed in a system?

The signal starts at 0.5 V for zero pressure and rises linearly to 4.5 V at 500 psi, giving a 4 V span that a controller can scale directly to the full pressure range.

How does the 3-Pin Packard connector limit the wiring options?

The three-pin Packard plug carries power, ground and signal only, so the transducer must be wired to a compatible 5 V DC supply and a single-ended voltage input — no current-loop or differential connections are possible.

What mounting clearance does the SAE 45° flare male fitting need?

The 1/4 in male SAE 45° flare threads into a matching female port and requires enough wrench swing to tighten the hex without stressing the stainless-steel housing.
