SINGLE-CHANNEL SYSTEMS
(for torque and other measurements)
AT-4500 EasyApp
AT-4400 split clamp collar mounted systems
Induction powered telemetry: AT-4500 EasyApp and AT-4400
Sensor data is directly measured and digitized on a rotating shaft with 16 bit resolution, and is transmitted
off-shaft using wireless technology. The receiver outputs high bandwidth analog data.
Applications: Torque, Temperature (RTD), and Electrical measurements on a range of equipment from
vehicle drive shafts, turbomachinery, and motor/generator field excitation.
Product features:
 Induction power for continuous use without batteries. No rotation is necessary for power.
 High accuracy/ low noise, 16 bit resolution, high sample rate (26484 Sa/sec), and bandwidth up to 8.3
kHz (2kHz is standard)
 Remote shunt calibration control at any time
 Analog voltage output (adjustable up to +/- 10 volts)
AT-4500 EasyApp
Applications range from automotive driveshafts to large turbomachinery. Product features include:
 No batteries!
 Reusable transmitter for multiple shaft sizes (2” to large shaft OD), using simple Kevlar straps.
 Precision balance and up to 10000 pound rated Kevlar straps for high RPM applications – from
automotive to turbomachinery
 Environmentally tough packaging --mud/ ice/ oil resistant
 Excellent rotor-to-pickup coil movement tolerance
Battery powered telemetry: AT-5000 EasyApp
The AT-5000 EasyApp directly measures torque, then digitizes and
transmits data off rotors. Applications range from automotive half
shafts to large turbomachinery
 Easy application: strap to a shaft in 3 minutes
 Capable of high g-forces by use of counterweighted Kevlar strap
 Small size- typically requires < 0.9” radially
 Long operating life from an internal battery — 150 hours for 1000
ohm strain gage (50 hours for 350 ohm gage)

MULTI-CHANNEL SYSTEMS
AT-7000 systems
AT-7000 Multi-channel Telemetry
High bandwidth, 12 or 16 bit resolution systems for multiple sensor inputs (2 to 256).
Sensors: RTDs, strain gages, thermocouples, rotating proximity probes, field voltages, accelerometers.
Applications: Virtually any rotary sensor or voltage static or dynamic signal measurement, including
strains on turbine parts, gears, temperatures, pressure, and proximity probes on hydro-generators.
Product features:
 Inductive powered for long term operation
 Outputs are convenient: analog 4/20 mA, +/- 10V, or digital
 Mounting with split clamp-on collars or customized end of shaft packages
 Customized solutions for specific combinations of sensor needs (i.e. 8 RTDs with 16 strain gages)

SYSTEMS
AT-8000 Systems
AT-8000 Series Ground Fault Monitors (EFREM and Rotor Health Monitor)
The Earth Fault Resistance Monitor (EFREM) and the Rotor Health Monitor (RHM) provide wireless rotor ground
fault monitoring for generators and motors. The systems replace older slip ring contact ground fault detectors
on any synchronous generator or motor.
These rotor ground fault detector systems provide:
 Continuous ground fault resistance measurements, trending fault severity and location
 Dual alarm relay contact outputs for user-configurable insulation resistance limits
 4/20mA output of log of ground fault resistance and other parameters
 Field excitation voltage level monitoring
 Field current (and average field temperature) available on some models
 RTD measurements (up to 24 sensors) available with the RHM model

If it rotates, we can instrument it &
provide real time wireless data.
Here’s how:
Accumetrics wireless telemetry systems amplify analog sensor signals on rotary shafts, then
digitize and transmit the data from the rotor to the stationary receiver, providing a reliable, EMIresistant alternative to slip rings and older FM telemetry systems. Available in single and multichannel configurations, Accumetrics telemetry systems preserve data integrity under the most
challenging conditions.
Advanced telemetry systems for serious applications:
Accumetrics manufactures the world’s most advanced, most accurate, most reliable telemetry
systems. They have been used to instrument half-shafts, drive shafts, turbines, motors,
generators, helicopter blades, wind turbines and much more, and they can meet your needs for:
