Digital tachometer

The CG4 instrument is a microprocessor tachometer with a 4-digit display (0-9999) that processes signals supplied by sensors with frequency output.
The microprocessor programming which is carried out by the means of the keyboard behind the front panel, allows setting all the parameters governing the working of the tachometer. The kind of input sensor can be selected between the keyboard from: NPN, PNP, namur, pick-up and mechanical contact. Working mode as a frequency meter or period meter, make the CG4 a complete tachometer suitable for many applications. The instrument’s reading scale can be set in r.p.m., meters/minute, meters/hour, and it’s possible to work with it as a frequency meter.
• Version: CG4-2 has two relay devices with programming thresholds. The instrument is set into a vertical panel case 48x96 according to DIN 43700 standards.

The GX1 instrument is a programmable microprocessor instrument with a 6 digit display which can be used as a counter of frequencies, periods, revolutions, pieces and meters.
The counter elaborates signals supplied from linear sensors, amplified and not amplified inductive sensors, mechanical contacts. On production counter working mode, the instrument is in order to govern two inputs with total pieces counting and the partial one, with the hour production and working time display. The microprocessor programming, by the means of 4 keys set on the front panel, allows the setting of all parameters that govern the working of the instrument: that spreads the possibilities of employment and makes the GX1 instrument versatile and available for different employments.
