BMeasure-125i - Accessories

The BMeasure-125i has been developed to interface to a wide range of sensors. In some cases some form of preconditioning or amplification may be desired. The schematic show an amplification front end. This has been implemented as a small PCB that plugs into a BMeasure-125i input channel. The user can populate the PCB with component values to provide the gain and filtering required for a particular application.

This accessory enables a user to connect via a BNC style connector and configure AC/DC coupling and attenuation by fitting the appropraite components to the PCB supplied. As well as a passiveconnection, the board supports a constant current source for the connection of IEPE style sensors.

This accessory proves a 5x input attenuation to allow the BMeasure-125i to measure in a +-60 Volt range.

This accessory enables a user to accurately calibrate a BMeasure-125i. The unit provides a 2.5 Volt accurate reference voltage for this purpose. The exact voltage is printed on the unit.

This accessory is designed for use in energy monitoring applications. It provides an isolated interface to a 240V 50/60 Hz line phase. This allows the line voltage to be accurately measured, both amplitude and phase, for accurate power measurements in conjunction with current transformers connected to other BMeasure inputs.
