Johnson Controls Inc P499RCP-101K pressure transducer 0 to 100 PSI
Measures 0 to 100 psi with ±1 % accuracy, 0.5 to 4.5 V DC output and IP67 stainless-steel housing
- Measures 0 to 100 psi for broad pressure monitoring
- Outputs 0.5 to 4.5V DC for direct controller integration
- IP67 rating resists dust and water in harsh environments
- Operates from -40 to 185 °F across extreme conditions
- Stainless steel housing with SAE 45° flare ensures durable sealing
Pressure Transducer 0 to 100 PSI
The Johnson Controls P499RCP-101K measures system pressure from 0 to 100 psi with a 0.5 to 4.5V DC output. It suits technicians maintaining pressure washer equipment who need a direct replacement sensor. The stainless steel housing and IP67 rating allow installation in wet, outdoor environments. Buyers needing a different pressure range or output protocol cannot use this model.
1/4 in SAE 45° Flare Male Connection
The sensor threads into a 1/4 inch SAE 45 degree flare port using its male process connection. A 3-pin Packard connector provides the electrical interface for the three-wire circuit. It requires a 5V DC power source to operate the 0.5 to 4.5V signal output. Systems lacking this specific flare fitting or connector type will need an adapter.
IP67 Rated for -40 to 185 °F Operation
The transducer maintains its +/-1 percent full-scale accuracy across a temperature span of -40 to 185 degrees Fahrenheit. The IP67 sealed stainless steel body resists water ingress during sustained wash-down cycles. Continuous exposure to pressure spikes near the 100 psi limit does not degrade the calibrated output signal. Installations exceeding this temperature or pressure envelope will lose specified accuracy.

Questions about this item
Will the 0.5 to 4.5V DC output signal remain within the +/-1% accuracy spec when the transducer runs continuously at 185°F?
The transducer is rated for a maximum operating temperature of 185°F with an accuracy of +/-1% of full scale, so the output should stay within specification at that temperature.
Does the IP67-rated stainless steel housing keep noise or heat low enough for all-day operation in a wash bay?
The IP67 rating protects against dust and water ingress; the housing is stainless steel and the unit operates on 5V DC, but no acoustic or thermal dissipation figures are provided.
My pressure washer uses a 1/4 in SAE 45° flare port — will the male process connection on this transducer thread straight in?
Yes, the transducer has a male 1/4 in SAE 45° flare process connection that matches that port, and it uses a 3-pin Packard connector for the electrical side.
