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
- Pressure
- Relative Humidity
- Rotation
- AutoMarker
- Conductivity
Temperature
The configuration of the sensors is also very extensive:
- Single Rigid Sensor
- Double Rigid Sensor
- Single Flexible Sensor
- Double Flexible Sensor
- Double Sensor With One Rigid And One Flexible Sensor
- Quad Flexible Sensor
Extreme Temperature Sensors
The standard temperature range is 0°C to +150°C, but it is possible to order
sensors which can be calibrated and measure down to -196°C or up to +400°C.
The logger has to be placed outside of the environment when measuring at -196°C. When measuring from +150°C up to 400°C, an insulation pack (thermal barrier) is required. The principel is to insulate the logger for a limited amount of time keeping the logger below +150°C. 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:
- Logging of the holding time start/stop from autoclave controller
- Logging of the door openings in warehouse storage, stability chambers, freezers, incubators etc.
- Logging of general failure of critical components during process e.g. pump failure
- Logging of emergency shelf cooling activation in freeze dryer
Conductivity
The Conductivity Sensor is compatible with TrackSense Pro Sky option to provide live data if required. Conductivity measurements apply to the control / monitoring of industrial processes and to validate the washing disinfecion processes in hospitals governed by regulation EN ISO 15883:2009.
Often conductivity is measured in combination with pH measurements.
Examples of applications the Conductivity Sensor would be used in are:
- Pharmaceutical Industry
- Hospitals
- Fermentation
- Food and Beverage
- Sugar Industry
- Petro-Chemisty
- Chemical Industry
- Power Plants
