THE testo 175-S1 and S-2 is an easy and affordable logging of current and voltage in industrial processes.
The compact dataloggers can be looped into the incoming line of a transmitter in order to log or monitor current signals.
The dataloggers are available in the versions 175-S1 without display and 175-S2 with display. Advantage of version with display: direct display of the scaled signal. Scaling is completed via ComSoft. User-friendly operation, easy analysis. Non-volatile memory for secure data, even if the battery is empty.
The new testo 581-limit signal output makes it possible to send alarm messages to external components, e.g. horns, lamps, PLC.
The external components are connected via a terminal strip in the battery compartment of the testo 581; the signal is transferred via the floating signal output. This can be set as an NC or NO contact.
The testo 581 is simply attached to the testo 175/177 dataloggers. Communication between testo 175/177 and the limit signal output takes place via the infra-red interface.
The user is informed directly, at the touch of a button, if the alarm has already been triggered. The alarm of the external components, e.g. the horn, can be reset using the reset button.
The testo 581 limit signal output is protected against splashwater (IP 54).
Alarm is triggered when:
* Programmed limit values in the datalogger are exceeded.
* Logger is stopped due to spent battery.
* Probe is disconnected.
* Alarm unit battery is spent.
The testo 580, available as an accessory, is a practical data collector which can read out a complete testo 175-S1+S2 datalogger in just a few seconds and buffer the values.
It collects the data from up to 25 loggers and transfers them to a PC. The data collector is connected to the PC and the data is read out and saved.
The datalogger remains suspended at the site and continues logging. It is therefore no longer necessary to collect all the loggers and redistribute them to their positions.
