EnviroMon Converters and Sensors
EnviroMon takes readings from a number of sensors. These sensors are connected to converters that transform the analogue signals from the sensor into digital signals: these digital signals can then be transmitted reliably and accurately to the logger over long or short distances.
Which converter is best for your application depends on what you wish to measure.
This page describes the current monitor.
EL040 Current Monitor
With the present drive towards energy efficiency the EL040 will find uses both at home and in industry. In industry currents can be monitored enabling more accurate costing to be placed on different tasks and find out exactly where a high percentage of current consumption is being made. Armed with this information decisions can then be made on methods of reducing or eliminating this in-efficiency, so saving money.
The EL040 enables an EnviroMon network to monitor three AC current signals. AC current clamps or current transformers are used to provide an input to the EL040. The EnviroMon can then be used to monitor current consumption or produce alarm conditions when consumption rises above or falls below preset limits.
