Wireless 4-20MA current loop sensor

Wireless 4-20MA current loop sensor

Overview

The 4-20mA sensor uses a 10-bit ADC to measure an analog value between 4 and 20mA with a 10uA resolution. If the measured value rises above or falls below the configured thresholds, an alert is sent over the wireless network. The Armored Sensor™ Outdoor/Industrial enclosure makes the sensor suitable for outdoor and industrial use.

The 4-20mA sensor can also be used as a bridge device to enable a wide variety of sensors with only a 4-20mA output. See the article Using Radio Bridge for  more information.
