Details

Choose the electrically isolated magnetic base when you need quick mounting without creating a ground loop.

DAQ7102 adds a 4 mA, 24 V constant-current source for IEPE/ICP sensors with USB and Ethernet data transfer.

304 stainless steel construction and a built-in IEPE circuit support stable, low-noise vibration monitoring in industrial environments.

Installation stays flexible with either a magnetic mount for fast setup or a threaded mount for secure permanent fastening.

Key specs for the WTVB-50P variant are summarized, including bandwidth, constant-current excitation, and IP65 protection.

DAQ7101 supports IEPE, voltage, and 20 mA inputs and includes a built-in constant-current source for sensor power.

WTVB501P includes a built-in IEPE preamplifier and works with common coaxial shielded cables to simplify test setups.

WTVB503P provides tri-axial X/Y/Z measurement in a compact body with IEPE signal conditioning.
