用途

  • Specially suited for automotive use. Developed in association with major car manufacturers, for high-quality field and laboratory measurement systems
  • Used with charge accelerometers, hydrophones, force transducers, condenser microphones, DeltaTron® accelerometers, DeltaTron preamplifiers, voltage input and sound intensity probes
  • Field recording of vibration and acoustic signals
  • Specially suitable for applications where shocks and impulses occur such as gas turbine testing and munitions testing (Types 2692-C and -D only)

特点

  • Highly flexible construction – 1, 2, 3 or 4 channel configurations, or a combination of acoustic and vibration transducer inputs is possible
  • High input signal range. Low noise. Extensive overload facilities
  • Supports transducers with TEDS according to IEEE 1451.4
  • Available for: charge, microphone, sound intensity, DeltaTron and very high input
  • Compact robust design and battery operation makes it suitable for use in the field (and in the laboratory)
  • Serial control interface (RS–232) allows computer control of setups and test functions. A large number of amplifiers can be controlled from a single PC
  • High accuracy due to reliable construction and a wide range of calibration options. Built-in patented Charge Injection Calibration (CIC) and patented Mounted Resonance Testing
  • Wide range of filters that can be set up for specific tasks
  • Rack-mounting fittings available

Portability and Rack Mounting

NEXUS Conditioning Amplifiers are equally suited for laboratory and field use. They are compact and self-contained with an optional rechargeable battery. They are lightweight too, weighing around 3 kg (6.6 lb.), including battery. Rack-mounting fittings are available for in-car testing purposes as well as for stationary use. The portable 19" rack KQ-0158 can contain up to 9 NEXUS units. Up to 16 NEXUS channels and a DAT recorder can be mounted in a compact unit (UA-1409) which is particularly suitable for automotive use. UA-1409 has fittings for a carrying strap.

Reliable Design

To survive the harsh electrical environment in cars, NEXUS conditioning amplifiers have specifications that far exceed the strict European EMC immunity requirements. ISO 7637-1®Road Vehicles – Electrical disturbance by conduction and coupling” requirements are met. Mechanical robustness is equally high and meets MIL – STD – 810C and IEC 60068 – 2 – 6 standards.

Environmental

Since all NEXUS amplifiers are built for portable outdoor use, they meet strict requirements for temperature and humidity. The operating temperature range extends from – 10 to +55°C (+14 to +131°F). The instrument will withstand rain if kept with the front panel facing upwards. However, because of the sockets on the back panel it is not watertight.
