Pressure transducer for 0-100 PSI monitoring

The Johnson Controls P499RCP-101C is a stainless-steel pressure transmitter built for 0 to 100 PSI service. It delivers a 0.5 to 4.5V DC output from a 5V DC supply with +/-1 percent full-scale accuracy. A 3-pin Packard connector and SAE 45-degree flare male fitting simplify installation in pressure-washer and fluid-system applications.

Suited for low-voltage DC control systems needing

Installers working with 5V DC controllers and a 0.5-4.5V input range will find this transducer a direct fit. The IP67 housing and -40 to 185 degree F operating span cover harsh outdoor and wash-down environments. Systems requiring a current-loop signal, a different supply voltage, or a threaded port other than 1/4-inch SAE flare cannot use this unit.

The 0.5-4.5V DC ratiometric output defines

This single electrical characteristic determines whether the transducer matches the input stage of the control board. Verify that the controller accepts a 0.5 to 4.5V DC signal powered from 5V DC before specifying the part.

Questions about this item

Which pressure range should I choose for my system?

This transducer covers 0 to 100 PSI with a 0.5 to 4.5V DC output, so select it when your working pressure falls inside that span.

What does the +/-1 percent full-scale accuracy mean once installed?

At the 100 PSI top end the reading can deviate by roughly 1 PSI across the -40 to 185 °F operating range.

What does the 3-Pin Packard connector and SAE 45° flare limit in practice?

The three-wire 5V DC interface and 1/4 inch male flare fitting fix the wiring harness and process port to those exact standards.
