New Tinytag Current/Voltage Loggers

The new battery-powered 1-channel data loggers with 16-bit resolution have a rugged housing with LCD display of the current readings. There is the model TV-4704 available with an input voltage range of 0-25V DC and a resolution of 1mV, as well as the model TV-4804 with the input current range of 0-25mA DC and a resolution of 1µA.

With the above mentioned current and voltage ranges a variety of industry standard sensors and transducers can be connected, which enables the recording of a wide range of process and environmental parameters.

The devices have a memory capacity of 30,000 readings and the housing protection is rated at IP67. They are supplied with an input connection cable.


The optional data logger software enables the scaling of the readings, that means, during the evaluation of the signals the real values of the connected sensors as well as the suitable physical units can be displayed. There are user-programmale sampling intervals between 1s and 10 days and 2 programmable alarms available, and there is also an option for delayed start up to 45 days, direct start via reed switch and three stop functions (when memory is full; after n readings or overwrite oldest data).

After the run is finished, the stored data can be transferred to a computer via an interface cable, and they can be displayed a s a curve or spreadsheet, printed or processed in other applications.
