Signal preamplifier 4022

explosion-proofsingle-channeltransmission

Signal amplifiers are used to transform the sinusoidal output of a Variable Reluctance Speed Sensor to a digital output (square wave signal) at the same rate as targets passing by. Several housing options are available. Puck styles can be mounted in electrical cabinets or dropped into many conduit elbows and enclosures. Plug-in styles can mount directly to VR Speed Sensors with connectors. Compact In-line styles can be added into wiring bundles or inside conduit. A Noise Cancelling Amplifier with additional noise filtering is also available for critical applications. This version also offers two separate output signals for driving two different systems or for prover applications. An optional third output can be included which can be optically isolated. A special Directional Sensing Signal Amplifier can be used with two appropriately placed VR Speed Sensors to determine a target’s speed and direction of rotation. Intrinsically Safe and Explosion/Flame Proof versions are also available for Hazardous Locations. APPLICATIONS • Flow metering • Engine speed (crank and flywheel) • Conveyor / Process speed • Process counting • Retrofit new electronic systems to older equipment Spectec's mag-preamps are designed to convert low level sinusoidal signals into stable square wave pulses. They can be used with all magnetic VR type pickups, allowing for greater pickup to target gaps and longer signal transmission distance. The pucks are built to fit “ELBY”, “Y”, or "GUAL16" type explosion-proof enclosures per 4001 Spec.
