System compatibilityPS3487 belongs to Fireye PS348 pressure transducer family. Compatible with Fireye legacy burner management controllers. Suitable for industrial steam boilers, thermal oil heaters and process furnaces for steam / fuel oil pressure measurement. This model is obsolete and discontinued, used units are mainly for spare replacement of old combustion control systems.
FunctionPS3487 is pressure transducer manufactured by Fireye. It detects oil or steam pressure via stainless steel isolation diaphragm and converts pressure value into 1-5VDC analog signal for burner controller. Built-in temperature compensation reduces measurement deviation under changing temperature. It provides real-time pressure feedback for combustion power regulation and boiler high / low pressure interlock protection. Widely deployed for old industrial boiler pressure monitoring and spare replacement.
InstallationFollow lockout/tagout safety procedure before installation. Mount PS3487 on pressure tapping port. Run 3-core shielded signal cable to connect transducer and burner controller strictly follow Fireye wiring manual. Complete zero calibration and pressure signal test during commissioning. Install condensate siphon when measuring steam medium.
InterfaceStainless steel sensing diaphragm,NPT process thread,three-core 1-5VDC signal cable,metal transducer housing for Fireye PS3487.
FeatureOriginal Fireye PS3487 pressure transducer,10~330PSIG measuring range,1-5VDC output for oil and steam service,UL & FM safety certified. This obsolete spare unit is used for legacy industrial boiler burner pressure measurement and combustion control system maintenance.
DiagnosticNo output voltage: Inspect 24VDC power supply,wire breakage and terminal connection. Reading drift: Perform zero calibration,check diaphragm contamination or scaling. Unstable voltage signal: Check cable shielding,vibration and high temperature radiation. Signal fixed at minimum value: Inspect diaphragm damage caused by overpressure.
Product BriefPS3487 is Fireye legacy PS348 series pressure transducer with 10~330PSIG range and 1-5VDC output,for oil and steam pressure monitoring,classic spare for old industrial boiler combustion control system.
