Yoctopuce Yocto - milliVolt - Rx - BNC
Valarm Tools Cloud / Tools.Valarm.net supports this milli Volt sensor adapter.
This device will let you connect a Valarm compatible connector device (like GSM sensor hubs, WiFi sensor hubs or Ethernet sensor hubs) to any industrial sensor for monitoring and recording the status of your industrial assets. Your Industrial IoT, remote monitoring, and sensor telemetry information will be available at tools.valarm.net.
The Yocto-milliVolt-Rx-BNC device is a high precision USB voltmeter. It will let you measure by USB very small voltages (down to a few dozens of microVolts, and up to 2V max), even when they are generated by extremely weak sources (very high impedance). The BNC connector makes it possible to bring the signal using a shielded coaxial cable.
Typical applications include measurement of electro-chemical reactions (e.g. pH and redox probes), low-voltage sensors (e.g. gas sensors, etc.) or Wheatstone bridges (e.g. load cells, etc). It is also possible to use this device to precisely measure the voltage drop across a shunt to measure high currents.
The input circuit of this device uses a very low bias current amplifier (typ. 0.2 pA). The measure circuit is electrically isolated from the USB bus, which makes it possible to measure grounded voltages without risk of creating a ground loop.
