HB-01 HiBand Preamp

The HB-01 HiBand Preamp is a single-channel, high-bandwidth, low-noise charge amplifier for single- or multi-element non-contact capacitance probe. The HB-01 provides low-noise dc bias for probe. The Preamp can operate with long cables to probe (up to 30 feet max recommended). The preamp output has 50-ohm impedance for driving long coaxial cables to data acquisition system (up to 1000 feet or more). When combined with Aerogage’s proprietary signal processing and Vibration Monitor System, the HB-01 is capable of high-accuracy measurement of tip clearance of individual blades on rotating turbine engines. The patented vibration software eliminates effects of cable vibration and provides long-term absolute calibration.  please call for pricing
