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 3-channel temperature converter.

EL001 3-Channel Converter (Temperature and Switch Position)

The three channels on the EL001 can measure any mix of temperature or switch position. The following sensors are available, all have 5 meter leads for connecting to the converter.

• EL029 Switch position / door switch sensor The switch module is commonly used to monitor whether a door is open or closed. In normal use a (supplied) magnet is attached to the door to be monitored and the EL029 to the door frame. Alternatively an external microswitch (not supplied) can be wired in. The display on the logger reports either 'Open' or 'Closed'.
• EL015 Temperature sensor The EL015 is a precision resistive sensor suitable for measuring temperature from -30°C to +70°C. Unless the temperature you need to measure is outside this range this sensor represents the best choice for measuring temperature.
