Data Acquisition Units - Data Loggers

...Remote or Real Time Units

A data logger or datalogger is an electronic device that is used in conjunction with a computer to monitor or record various signals.

The data logger may have internal sensor(s) so it measures where it is located or it may have one or a number of channels where external sensors can be connected. Some data loggers can be configured to accept a wide range of sensors.

Using the computer, the data logger is programmed to "wake up" at predetermined intervals, take a reading and go back to sleep. The time period between readings is called the "sample period" and can range from many readings per second to once per day. The data logger will have an internal memory where the readings are stored. Once this memory is full, the data logger can be programmed to stop taking new readings, and therefore not loose any readings or, overwrite the oldest reading.

Once the data logger has been monitoring for the required time period, it is connected to the computer. The stored readings are then downloaded and saved on the computers hard disk. A graph can now be produced showing the measured signal over time - providing an accurate account of what the data logger measured - useful for proving a shipment got too hot in transit or that your office is too hot to work in!

Data loggers are used in a wide variety of applications from simple monitoring of temperature in an office environment to monitoring the temperature of perishable products in transit or optimising the production process of food, pharmaceutical or engineering products. The same data logger can be used in a variety of applications, if you want to make a record of:
  • Temperature
  • Temperature e Relative Humidity
  • Process Signals
  • Weather Stations

Temperature Data Loggers
 
All these data loggers can be used to monitor temperature and a wide range of applications. From simple office environment monitoring, through process monitoring and monitoring temperature sensitive products in transit. Many are single channel data loggers but some, can be configured to accept multiple sensors, like SL7000, SL1000 e SL2100 . Wireless environmental monitoring systems for measuring temperature and relative humidity and transmitting the readings back to a central location are available with SL400 e spYdaq systems.
 
Features
 
  • Temperature range up to +140ºC, without thermal barrier
  • Disposable or multi-use dataloggers, with automatic generating PDF report
  • Wide range of available models with different sizes and shapes, as small as 6mm high and 17mm of diameter, or as USB pen drive
  • Water resistent models and completely sealed
  • Available with free software for easy configuration and data visualization for analysis

Temperature and Relative Humidity Data Loggers
 
All these data loggers can be used to monitor temperature and relative humidity in a wide range of applications. From simple office environment monitoring, through process monitoring and monitoring relative humidity and temperature sensitive products in transit. Some can be configured to accept multiple sensors, like the SL7000 . Wireless environmental monitoring systems for measuring temperature and relative humidity and transmitting the readings back to a central location are available with SL400 e spYdaq systems.
 
Features
 
  • Temperature range from -20ºC up to +85ºC and relative humidity range up to 100%RH
  • Temperature accuracy up to ±0.5ºC and resolution of 0.07ºC
  • Relative humidity accuracy of ±2%RH and resolution of 0.04%RH
  • Wide range of available models with different sizes and shapes, as small as 6mm high and 17mm of diameter, or as USB pen drive
  • Supplied with TempIT software for easy configuration and data retrieval for analysis

Process Signals Data Loggers
 
These data loggers accept most common industrial signals like 4/20mA, milliVolt and Voltage signals. The SL1000 and SL2100 can also be configured in the software for thermocouple input. The SL7000 can also be configured for mA, Voltage, Thermocouple, Pt100 (RTD) and slidewire inputs - all be selecting the input required in the software, no need to specify at the time of order.
 
Features
 
  • Universal inputs, including RTD/Pt100, voltage, current, thermocouples and relative humidity
  • Up to 500,000 readings
  • Roughed housing materials available in ABS or extruded aluminium
  • Data logging in modes &quot;off-line&quot; to internal memory or &quot;on-line&quot; when connecting to a PC
