Yoctopuce Yocto - 4-20mA - Rx Sensor Adapter

Published on : Tuesday 30-11--0001

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 up to two 4-20mA sensors.The 4-20 mA signaling standard is a broadly adopted industry standard for reliably sending sensor data along great distances over inexpensive wiring (thousands of feet and meters).

Here are some real world applications where this exact sensor adapter is used with Tools.Valarm.net for monitoring:

• Water levels / depths in wells
• Chemical, liquid, & fluid levels in tank farms
• Water levels and volumes in ponds
• Water quality monitoring
• Flood monitoring systems

These Yocto-4-20mA-Rx sensors allows you to monitor and record the status of up to 2 4-20mA sensors. The 4-20 mA signaling standard is a broadly adopted industry standard for reliably sending sensor data along great distances over inexpensive wiring (thousands of meters).

You can use this flexible 2-channel device for an incredibly broad array of applications like:

Water Resources Management - Telemetry for Water Usage, Water Well Levels, Fluid Flow Meters

• Chemical Distribution, Tank Levels, Fluids Monitoring
• Soil Moisture
• Flood Monitoring Systems
• Leaf Wetness
• Precision Temperature
• pH, turbidity, salinity, conductivity, resistivity, Total Dissolved Solids (TDS), Dissolved Oxygen (DO), and other water quality factors
• Pressure (Fluid / Gas)
• Linear & Rotary Position Sensors
• Hydraulics
• AC Current sensors
• Chemicals and Gases, e.g., H2S (Hydrogen Sulfide) & NH3 (Ammonia)
• Water Monitoring Solutions & Systems

These are just a few ideas that come to mind when you realize that any sensor implementing a 4-20mA interface is now connectable via USB.

You can find sensors for all kinds of physical measures using the standard 4-20mA interface. Transmitting the measure using a 4-20mA current loop makes it possible to get a very precise reading (up to 0.01%), and works even when the sensor is far away from the module.

The Yocto-4-20mA-Rx support 2-wire sensors (powered from the current loop) as well as 3-wire sensors (sensors that require an additional power supply with shared ground) and 4-wire sensors (with an isolated power supply). It can even provide up to 80mA to power 3-wires sensors that do not require too much power. The supply voltage is regulated 23V, isolated from the USB bus but common to both inputs.
