TrackSense® Pro Sensors
Ellab offers the largest range of different sensors with 1, 2 or 4 channels. Sensors are interchangeable, enabling the user to change sensors for different applications. This reduces costs because one set of TrackSense® Pro loggers can be used for temperature, humidity and pressure studies.
The temperature sensors can be delivered in rigid, semi flexible and flexible material for ease of use. New sensors are available with or without LED that shows the status of the logger. An active, communicating logger is identified by a green blink. Loss of communication between the logger and Access Point is signaled by a red blink. This feature makes it much easier to start larger groups of loggers and helps avoid using unprogrammed loggers. In the case of an LED sensor being used in combination with a Sky module, the LED will confirm communication status.
The TrackSense® Pro sensors cover parameters such as:
Temperature
The configuration of the sensors is also very extensive:
Extreme Temperature Sensors
The standard temperature range is 0 oC to +150 oC, but it is possible to order sensors which can be calibrated and measure down to -196 oC or up to +400 oC.
The logger has to be placed outside of the environment when measuring at -196 oC. When measuring from +150 oC up to 400 oC, an insulation pack (thermal barrier) is required. The principel is to insulate the logger for a limited amount of time keeping the logger below +150oC. Please consult your local Ellab representative for specific time and temperature limits.
Pressure
The pressure sensor can be used as a stand alone sensor to measure the pressure in e.g. the autoclave itself, but can also be mounted with a connection system to facilitate measurements in small containers without having to place the logger inside the container.
Relative Humidity
To achieve the best results in measuring relative humidity it is necessary to chose the right design of the sensor. The sensor needs to be protected if used in harsh, corrosive conditions such as an EtO sterilizer. If the sensor is not protected, initial results will be satisfactory but the conditions will affect the sensor and the sensor will eventually start drifting. Therefore, Ellab's sensing element is protected by a filter but contains special openings to increase air run through.
AutoMarker
The AutoMarker sensor can be used to record events during a session. When started, time markers can be added to the session either by manual activation of the switch placed at the cable end or automatically when connected directly to a PLC using the PLC relay function.
Examples of AutoMarker sensor use are:

Rotation
The Micro logger is designed for applications where size is an issue, like e.g. in the following applications: hydrostats, spiral cooker/coolers and rotation retorts. With a diameter of only 15 mm, it is ideal for pressure, rotation and temperature measurements inside bottles, PET bottles, small containers and pouches.
The Micro logger is available for temperature, rotation, pressure or for combined temperature and pressure measurements.
