Honeywell 3090A speed sensor
The Honeywell 3090A is an intrinsically safe variable reluctance (VRS) speed sensor designed for explosion-proof hazardous environments. It requires no external power supply and senses the rotational speed of ferromagnetic targets by changing reluctance, outputting an AC signal. It is suitable for speed monitoring and safety protection of equipment in hazardous areas such as petrochemical and oil and gas extraction, and is a core component for speed measurement and fault early warning of critical industrial equipment.

Core Parameters and Specifications
Item Parameters
Product Type Intrinsically safe VRS magnetoresistive velocity sensor, explosion-proof certified
Working Principle Passive magnetoresistive induction, no external power supply required, generates an AC signal by cutting a magnetic field through a ferromagnetic target object
Explosion-proof Rating Class 1/II/III, Groups A/B/C/D/E/F/G (US/Canada standards), explosion-proof sealed installation compliant
Output Characteristics Minimum 60Vp-p AC voltage, coil resistance 191-280Ω, response frequency up to 40kHz
Measurement Range Minimum surface velocity 0.38m/s (15IPS), compatible with 12DP and above gear pitch
Mounting Specifications 5/8-18 UNF-2A thread, 45mm length, 3-meter two-wire cable, 35mm DIN rail mounting
Environmental Tolerance Operating temperature -73℃ to 93℃, vibration resistant (compliant with Mil-Std 202F), corrosion resistant stainless steel housing
Core Advantages Passive and maintenance-free, explosion-proof and safe, wide temperature range, stable signal, suitable for harsh working conditions.
Core Functions
Passive Speed Sensing: An internal permanent magnet generates a magnetic field. When a ferromagnetic target (gear/disc) passes through, the induction coil outputs an AC voltage proportional to the speed. No external power supply is required, making it suitable for scenarios without power supply.
Explosion-proof Safety Monitoring: Explosion-proof structure and installation specifications ensure safety in hazardous areas, suitable for speed monitoring in flammable and explosive gas/dust environments.
Wide Operating Condition Adaptability: Resistant to high and low temperatures and strong vibrations, suitable for harsh industrial environments, ensuring long-term stable operation.
Direct Signal Output: 60Vp-p high output voltage, strong anti-interference capability, suitable for long-distance cabling and high-impedance loads, allowing direct connection to PLC/DCS without signal conditioning.
Maintenance-Free Design: No moving parts, stainless steel casing, 3-meter direct cable connection, reducing on-site maintenance costs.
