Accumetrics, Inc. Telemetry Systems

For Automotive, Aerospace, Marine, Motor & Generator Health, Energy, Power Plant, and Industrial Applications

Accumetrics, Inc. (a PCB Group Company) offers a simple, accurate method of conditioning and transmitting strain, thermocouple, voltage, or ICP® signals on rotating or moving machinery while operating in a completely contact-less mode. This configuration allows users to measure torque without interrupting existing shaft systems to install in-line torque transducers. Our comprehensive line of telemetry products includes battery and induction powered products to meet the specific needs of automotive, aerospace, marine, energy, power plant, test benches, motor and generator health, and industrial applications.

Single Channel Telemetry Systems

Battery Powered Solutions

Our battery-powered digital telemetry systems feature a low mounting profile and low power consumption. These systems use a small battery powered transmitter mounted with a heavy-duty aramid fiber strap to directly measure, digitize, and transmit true torque data from rotating half-shafts, drive shafts and rotors of most sizes and speeds. The system is also used for temperature, voltage, and acceleration sensing.

AT-5000 EasyApp

AT-5000 EasyApp

  • Easy application and installation
  • Small size – typically requires only 0.7 to 0.9 inch radial shaft clearance
  • Long operating life from internal battery – 150 hours for 1000 ohm strain gage (50 hours for 350 ohm gage)

Induction Powered Solutions

We offer induction powered solutions ideal for long duration applications where accuracy, resolution, low drift, and low noise levels are critical. The induction power eliminates the need for batteries. Sensor data is directly measured and digitized on a rotating shaft then transmitted off-shaft using wireless technology. The receiver outputs high bandwidth analog data. These systems are ideal for taking precise measurements for torque, strain, temperature (RTD) and voltage on drive shafts of motor-generator field excitation.

AT-4500 EasyApp AT-4400 EasyApp

AT-4500 EasyApp

  • Simple-to-apply aramid fiber straps for small or large shaft diameters
  • A single transmitter can be reused on varied shaft sizes
  • Excellent rotor-to-pickup-coil movement tolerance
  • Environmentally rugged transmitter housing

AT-4400 EasyApp

  • High EMI immunity (usable near variable frequency drives)
  • Flexible output gain, offset, and filtering
  • High RPM capability
  • Rugged collars ideal for long-term use

Multi-Channel Telemetry Systems

Induction Powered Solution

Our induction powered Multi-channel Telemetry System allows machine designers and maintenance personnel to measure exactly what is happening on the rotating components of their equipment while it is in operation - without the need for slip rings. The AT7000 multi-channel systems can combine any customized mix of ordinary sensors: strain gages, thermocouples, RTDs, accelerometers, as well as motor/generator field voltages, currents and ground fault currents. The received data is continuously streamed to the user as analog (+/- 10V or 4/20mA) or digital data.
