Accumetrics, Inc. products

The AT-8000 Earth Fault Resistance Monitor (EFREM) provides continuous wireless monitoring of insulation fault resistance and field voltage on brushless exciter generator/motor field windings, combining advanced ground fault measurement techniques with the latest innovations in digital telemetry. The system also provides users with condition monitoring data, allowing operators to monitor trends over time in order to make better informed operational and maintenance decisions.

The Static Exciter Ground Fault Detector Model AT-8100 provides continuous wireless monitoring of insulation fault resistance and field voltage on brushed exciter generator and motor field windings, combining advanced ground fault measurement techniques with the latest innovations in digital telemetry. The system also provides users with condition monitoring data, allowing operators to monitor trends over time in order to make better informed operational and maintenance decisions.

The Accumetrics` Battery Powered Telemetry System Model AT-5000 EasyApp provides easy, dependable wireless measurements, including torque measurements, strain measurements, and more, from a rotating shaft. Measure torque live in real-time with this battery-powered, digital telemetry system. Featuring a low mounting profile and low power consumption, the system requires no shaft modifications and is fastened to the shaft using a single, sturdy aramid fiber strap. AT-5000 EasyApp is an ideal non-contact data transmission solution for applications requiring easy installation and dependable data retrieval, even in high RPM applications.

The Induction Powered Telemetry System Model AT-4500 EasyApp is an induction powered 16 bit rotor telemetry system. This system is easily installed, without any shaft modification, using an aramid fiber strap. Using wireless technology, sensor data can be directly acquired for broadly varied applications -- from vehicle drive shaft torque to large generator excitation voltage.

The Accumetrics` Multi-Channel Telemetry System Series AT–7000 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 system 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 measurements are continuously streamed to the user as analog (±10 V or 4-20 mA) or digital data.
