High-Voltage Safe Measurement Systems 
High-Voltage Safe Measurement Systems
The FL100 has been specifically designed for measuring analog voltages from IEPE sensors, such as triaxial accelerometers, in high-voltage environments.
The FL100 is equipped with three analog inputs and provides a modified sensor excitation for the connection of IEPE sensors. If combined with special sensor cables, standard IEPE sensors, which are typically used in low-voltage applications, can now be safely operated even in high-voltage environments. This allows customers to re-use their investment in standard sensors.
As a slide-in unit for 19-inch DIN racks, this measurement module is ideal for use on test benches. Combined with the optional mounting frame and IP65 rating, the HV IEPE3 FL100 is a good choice for mobile use in vehicles, allowing it to be mounted securely inside a vehicle’s trunk or passenger compartment.
