What is TTSL and how does the system function?
The TTSL base unit is a device controlled by a DSP (Digital Signal Processor) for recording temperature, humidity and other variables.
This device was developed for mobile remote monitoring of climatic conditions, working processes and machine statuses.
The TTSL system comprises sensors, a data recording unit with GSM modem, the PC Software Control Centre and a modem with analogue connection for the mains.
The Control Centre manages up to 100 systems – up to 100 objects! – at the same time, recalls the data of each registered TTSL via GSM and stores them in a database. The graphical representation gives you a rapid overview of the measurement process.
The interrogation interval can be set individually for each TTSL. The parameters for each device, such as Alarm and Info threshold values etc., can be set from the Control Centre. In case threshold values are exceeded or undershot, an SMS “alarm” or info message is sent to up to two pre-specified telephone numbers (e.g. the two responsible service technicians).
Furthermore, the auto-SMS function allows an SMS notification to be sent twice daily to these two numbers, at freely-definable times of day.
Of course, the data of each TTSL can be directly recalled via SMS at any time, if required. As with the auto-SMS function, no Control Centre is required in principle.
Depending on the model, the system has between one and eight connections for a wide variety of measurement sensors.
These sensors can be connected in any desired combination: temperature/humidity, resistance, voltage/current, digital 0/1 (current circuit open/closed), etc.
If the two sensor types temperature/humidity and voltage/current are exclusively used, it is even possible to record up to 8 values with one base unit (TTSL 4) since both sensor types give two values at one connection.
The TTSL has automatic sensor type recognition which allows connection of any desired sensor to each channel without the sensor type having to be selected.
Climate data, cooling curves, fill states, machine statuses and all other measurement data can be printed out in a preconfigured report for documentation purposes and for presentation to the customer.
