Accumetrics

What Accumetrics does

Accumetrics, Inc. designs, assembles, and supports digital telemetry systems that transmit sensor data from rotating structures using wireless techniques, primarily serving industrial customers in energy and power generation, aerospace and defense, marine, rail, automotive, agricultural equipment, and industrial process monitoring. Founded in 1992 and headquartered in Latham, New York, the company pioneered ground fault detection technology and remains a global leader in rotor telemetry, with a portfolio organized into two main categories: rotor ground fault monitoring (AT-8000 EFREM, AT-8300 Rotor Health Monitor, AT-8600, AT-9000 Accutector, AT-8100) and rotating shaft measurement (AT-7800 multi-channel telemetry, AccuTemp temperature monitoring, AT-4400 single-channel induction-powered telemetry). Underlying technology centers on induction-powered wireless telemetry using RF transformer coils to deliver power and digital data across an air gap, eliminating slip rings and batteries, with 16 to 18-bit resolution, up to 100 dB dynamic range, and capability for high-RPM (up to 17,000 RPM) operation in high-EMI environments.

The business model is primarily hardware sales of customized telemetry systems, supplemented by commissioning, technical support, and field services (including 24-hour SensorLine support). Pricing is quote-based with no public disclosure, reflecting engineered, application-specific configurations rather than standardized catalog products. Go-to-market is sales-led, combining direct field sales across US states with a global distributor network covering 50+ countries, much of it channeled through the parent's international subsidiaries. Accumetrics is a wholly owned subsidiary of PCB Piezotronics, Inc., which is itself a wholly owned subsidiary of Amphenol Corporation (NYSE: APH), positioning the company within a large, financially stable sensor and instrumentation conglomerate.

Core offering

Accumetrics designs, assembles, and supports digital telemetry systems that wirelessly transmit sensor data from rotating structures, including ground fault monitoring systems for brushless synchronous generators and motors, multi-channel rotating shaft measurement systems, and rotor temperature monitoring solutions. The company pioneered ground fault detection technology using its proprietary EFREM Pulse Injection Method and offers induction-powered telemetry systems that eliminate the need for slip rings or batteries on rotating equipment.

Product overview

Accumetrics offers a portfolio of rotor telemetry products focused on wireless measurement solutions for rotating structures. The product line is organized into two main categories: Rotor Ground Fault Monitoring products (AT-8000 EFREM, AT-8300, AT-8600, AT-9000 Accutector, AT-8100) and Rotating Shaft Measurement products (AT-7800 Multi-Channel Telemetry, AccuTemp Temperature Monitoring, AT-4400 Single-Channel Telemetry). All products utilize wireless digital telemetry technology to transmit sensor data from rotating structures, replacing traditional slip ring solutions. The ground fault monitoring systems protect generators and motors from insulation degradation, while shaft measurement systems capture temperature, strain, torque, vibration, and pressure data for industrial, aerospace, marine, automotive, and power generation applications.
