FREQUENCY METER

The frequency meter is a equipment developed to realize the measurements of frequency in various applications uniting the digital numerical indication to a bicolor LED’s graphic bar, allowing the instant view of measured values, includes AC + DC true rms, operating up to 2kHz. It has a adjustable alarm with which it is possible actuate any external load when the read quantity is out of specified parameters and register the maximum and minimum read values. The LED’s bar enables a clear vision of the working range and also allows the showing of the reading average to a better view of the graphic scale division, facilitating the reading at distance.

Also has optional the RS 485 communication with MODBUS RTU protocol, making possible the connection with monitoring systems to register the required quantity.

ACCESSORIES

SUPERVISORY SYSTEM

With the supervisory system for digital indicators, it is possible view the values registerd by the instruments in a computer through MODBUS RTU communication. Also is possible create reports containing the measurements obtained and export or print them.
