Pulsar® model R86 26 GHz non-contact radar transmitter

Pulsar burst radar - Technology

Pulse Burst Radar emits short bursts of energy to a liquid surface. Ultra-high-speed timing circuitry measures the time of the signal reflected off the liquid surface.

Sophisticated signal processing filters out false reflections and other background noises. The exact level is then calculated, by factoring in tank height and other configuration information. The circuitry is extremely energy efficient so no duty cycling is needed as with other radar devices. This allows the device to track high rates of level changes up to 4,5 m/minute (180"/min).

Features

• Performance not process dependent (changing specific gravity and dielectric have no effect)
• 26 GHz operating frequency offers superior accuracy and resolution
• Antenna designs to +750 °F (+400 °C)
• Range up to 130 feet (40 meters)
• Quick connect/disconnect probe coupling allows vessel to remain sealed
• SIL 2 capable with Safe Failure Fraction (SFF) = 93.2% (FMEDA available upon request)
• PACTware™ PC software interface with new improved DTM

Opcionais

• HART® 7.1 and Foundation fieldbus™ digital communications
• 316 stainless steel dual compartment enclosure
• 1½" to 4" horn antennas
• Antenna nozzle extensions to 72" (1.8 meters)

Operating principle

PULSAR transmitter technology is based on pulse-burst radar technology together with equivalent time sampling circuitry. Short bursts of 26 GHz microwave energy are emitted and subsequently reflected from the liquid level surface.
