RH103T Low-Frequency Accelerometer
The RH103T is a low-frequency, high-sensitivity accelerometer with a built-in IEPE circuit, isolated output, and constant-current-source power supply. Offering 500 mV/g sensitivity, it is purpose-built for capturing slow-speed machinery vibration that standard sensors would miss. Its compact size and isolated output design make it ideal for permanent installation on low-RPM assets such as paper machine rolls, large cooling fans, and slow rotating pumps.
Measurement Type: Low-frequency vibration (acceleration)
Sensitivity: 500 mV/g
Circuit Type: Built-in IEPE, isolated output, constant-current source
Frequency Range: 0.2 Hz – 1 kHz (±3 dB)
