RH113 Low-Frequency Accelerometer
The RH113 is a low-frequency, high-sensitivity IEPE accelerometer with an isolated output and built-in constant-current-source power supply — optimised for capturing vibration on slow-speed rotating equipment where standard accelerometers fall short. With a compact body, isolated signal output, and wide dynamic range, the RH113 is the sensor of choice for monitoring paper mills, wind turbine main bearings, low-RPM mixers, and other assets where sub-hertz vibration content is diagnostically significant.
Measurement Type: Low-frequency vibration (acceleration)
Sensitivity: 500 mV/g
Circuit Type: Built-in IEPE, isolated output, constant-current source
Frequency Range: 0.5 Hz – 2 kHz (±3 dB)
