4–20 mA Sensors and Solutions

MP406 4-20		The MP406C with integrated 4–20 mA output interface has an analogue current loop output of 4–20 mA which can be used directly by industry standard irrigation controllers and cabling power systems and hence is ideal for use in Parks and Gardens, Golf Courses and similar installations.
GT3-420 Tensiometer		The GT3-420 has an industry-standard 4 to 20mA current loop output that can be used to interface it to a wide variety of standard devices including programmable logic controllers (PLCs) and data loggers.
ECH2O EA-10		The EA-10 sensor has a standard 2-wire, 4-20 mA analogue interface for use with industrial data acquisition and control systems. The EA-10 has a very low power requirement and high resolution. This gives you the ability to make as many measurements as you want over a long period of time (i.e. a growing season), with minimal battery usage.
4000L Infra-Red Thermometer		The ENVIRO-THERM Model 4000L Infrared Temperature Sensor is the traditional temperature sensor manufactured by Everest Interscience. It has been used extensively for continuous monitoring of crops and other targets in the natural environment. The standard output is Analog Millivolt at 10 mV/°C. It comes with an optional 0-5 Volt output.
