Main Features and Advantages​

Factory-Calibrated Precision(UNMP):As an unused(UNMP)sensor,MARPOSS 03RJ1425 87PSI arrives with factory-sealed calibration,ensuring±0.1%full-scale accuracy and 0.01 PSI resolution—eliminating the need for pre-installation recalibration.This guarantees immediate,reliable pressure measurement from the first use,critical for applications like automotive part leak testing where uncalibrated sensors could lead to false pass/fail results.​

Wide Environmental Adaptability:With an IP65 protection rating and operating temperature range of-20°C~+80°C,the sensor withstands dusty factory floors,high-humidity test chambers,and water jets during cleaning—making it suitable for both indoor manufacturing lines and outdoor industrial setups.Its vibration resistance(10g)further ensures stable performance near heavy machinery like stamping presses or robotic arms.​

Standardized Output for Easy Integration:The 4-20mA analog output(with optional RS-485 digital communication)aligns with MARPOSS’s E54 amplifier(7508021121)and most industrial PLCs/DCS systems.This plug-and-play compatibility reduces integration time,allowing the sensor to quickly connect to existing measurement networks for real-time pressure data transmission and remote monitoring.​

Media Compatibility for Versatile Use:Designed to work with hydraulic oil,pneumatic air,and non-corrosive fluids/gases,the 03RJ1425 87PSI UNMP adapts to diverse industrial applications—from monitoring pneumatic pressure in semiconductor wafer transfer systems to tracking hydraulic pressure in automotive suspension component testing.Its 1/4″NPT pressure port ensures secure,leak-free connection to standard industrial fluid lines.​

Application Field​

MARPOSS 03RJ1425 87PSI UNMP is a versatile pressure sensing solution for industries prioritizing precision and reliability.In automotive manufacturing,it is deployed in leak testing workcells for engine gaskets and fuel lines—measuring air pressure decay to detect micro-leaks that could cause performance issues or emissions failures.Its high accuracy ensures that even 0.1 PSI pressure drops are detected,meeting strict automotive quality standards.​

In semiconductor processing,the sensor monitors pneumatic pressure in wafer handling robots—ensuring consistent pressure for vacuum-based wafer gripping,preventing damage to delicate 12-inch wafers during transfer.Its IP65 rating and chemical resistance protect it from the cleanroom’s harsh cleaning agents,while its stable output integrates with MARPOSS in-line measurement systems to optimize process efficiency.​

The sensor also plays a key role in aerospace component testing,where it measures hydraulic pressure in landing gear prototypes during stress tests.Its ability to withstand extreme temperatures(-20°C~+80°C)and vibration ensures accurate data collection under simulated flight conditions.Additionally,in medical device manufacturing,the MARPOSS 03RJ1425 87PSI UNMP monitors fluid pressure in diagnostic equipment assembly,ensuring compliance with medical safety regulations and preventing equipment malfunctions.​

Installation and Maintenance​

Pre-installation preparation:Before installing MARPOSS 03RJ1425 87PSI UNMP,confirm the target pressure range(0-87 PSI)matches application requirements and verify compatibility with the power supply(12-24V DC)and connected devices(e.g.,E54 amplifier).Gather tools including a torque wrench(for pressure port),wire strippers,and anti-static wristband.Ensure the installation area meets temperature(-20°C~+80°C)and vibration(≤10g)limits,and clean the pressure port to remove debris that could affect readings.​

Installation steps:Screw the sensor’s 1/4″NPT port into the fluid/gas line,tightening to 15-20 N·m to ensure a leak-free seal.Connect the power cable(12-24V DC)to the sensor’s power terminals,following polarity guidelines to avoid damage.Wire the 4-20mA output to the amplifier/PLC using shielded cable,securing connections with 0.5-0.7 N·m torque.Power on the system and verify the sensor outputs a 4mA signal at 0 PSI and 20mA at 87 PSI(use a multimeter for validation).Calibrate the connected system to map the sensor’s output to actual pressure values via MARPOSS configuration software.​

Maintenance recommendations:Conduct monthly visual inspections of MARPOSS 03RJ1425 87PSI UNMP to check for pressure port leaks,loose wiring,or signs of physical damage.Clean the sensor’s exterior with a dry,lint-free cloth—avoid using liquids near the pressure port.Every 12 months(or as per application needs),use MARPOSS Calibration Kit 7508021190 to verify accuracy;recalibrate if deviations exceed±0.1%of full scale.Since the sensor is UNMP,avoid unnecessary handling to preserve factory calibration.In case of erratic readings,first check for fluid line blockages or power fluctuations before troubleshooting the sensor itself.​
