Pico Technology

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 available converters and sensors.

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.

EL041 Thermocouple Converter

The 4 channel EL041 thermocouple converter is designed to measure a wide range of temperatures with any thermocouple that uses a miniature size thermocouple connector.

Featuring built-in cold junction compensation (CJC), the EL041 has an effective temperature range of -270 to 1820°C (The actual temperature range depends on the thermocouple being used.)

In addition to temperature measurement, the cold junction compensation can be switched off to enable the EL041 to measure ±60mV signals.

Note: The EL041 is designed to work only with the EL005 logger.

EL030 Humidity / Temperature Converter

EnviroMon can measure humidity/temperature using the EL026 converter and EL030 temperature and humidity sensor. Each EL030 is calibrated for high accuracy measurements.

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.

* When using a 200 Amp current clamp which measures 1 Amp per mV.

TA011  300 Amp AC Current Clamp

Not being powered by batteries the TA011 is ideally suited to applications where current consumption is being monitored over long periods of time.

Removing the need to check the condition of the batteries regularly, makes the TA011 ideally suited for use with the EL040 current monitor when monitoring current consumption over months or even years.

EL037 General Purpose Converter (Voltage / Current Inputs)

The EL037 has 4 input channels when used with the EL005 logger (3 channels are available when used with the EL008), each channel can be be configured independently (using jumpers) to measure ±2.5 V, ±10 V or 4-20 mA. It can also route an external power supply (perhaps 12 V or 24 V, depending on the requirements of the input devices) to each of the input devices. Connections to the input channels are via screw terminals.
