Handheld Piezotron (IEPE) couplers, 1-channel / 5114

Handheld Piezotron (IEPE) couplers, 1-channel


This portable 1-channel handheld Piezotron (IEPE) coupler is powered by built-in battery and is suitable for the operation of Piezotron (IEPE) sensors.
  • Powered by built-in battery, AC power supply, or any DC voltage source
  • Sensor bias voltage display
  • Sensor and cable circuit integrity indication via LEDs (ok, short circuit, interruption)
The Type 5114 is a single-channel Piezotron (IEPE) coupler that provides constant current excitation required by low-impedance voltage mode sensors with built-in electronics (IEPE sensors). Sensor power is supplied by the same two-wire cable that provides the low impedance output signal. The Type 5114 decouples the DC bias voltage from the output signal. A 3.5 digit LCD indicates the sensor DC bias voltage. Three LEDs on the front panel indicate the basic status of the sensor circuit (ok, short circuit, interruption). The device operates from a single 9 volt battery or DC power from an external AC-DC power adapter. It can also be powered by external 12 volt DC power supplied through the 2.1 mm jack. A power switch is located on the front case.
