Tachometers and Counters

Tachometers and counters are indicating devices that process pulses coming from a sensor or contact: a counter totals the pulses to give piece count, revolutions or length, while a tachometer shows speed and line velocity from the pulse rate. They are used in packaging, filling, winding and cutting machines to monitor the number of parts produced, conveyor speed and shaft speed. The category includes Enda ECH series counters and tachometers, GEMO 4- and 6-digit counters, Tense digital counters and Isıso digital and mechanical counters; 48 × 48 mm and 72 × 72 mm housings and models with RS485 Modbus communication are available. Select the input type by the output of the sensor you will use (for example PNP), the number of digits by the largest value to be displayed, the counting speed by the pulse frequency, and the supply voltage and housing dimension by the panel. A counter counts pulses; it is not a substitute for an hour meter that accumulates the machine's operating time or an electric meter that measures consumption in kWh.

How to choose Tachometers and Counters

Tachometers and counters are indicating devices that process pulses coming from a sensor or contact: a counter totals the pulses to give piece count, revolutions or length, while a tachometer shows speed and line velocity from the pulse rate. They are used in packaging, filling, winding and cutting machines to monitor the number of parts produced, conveyor speed and shaft speed.

  • Separate sensing, motion control, logic processing and operator interface requirements.
  • Select signal type, supply voltage, communication protocol and I/O count for the machine network.
  • Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.

What should I compare when choosing Tachometers and Counters?

Select the input type by the output of the sensor you will use (for example PNP), the number of digits by the largest value to be displayed, the counting speed by the pulse frequency, and the supply voltage and housing dimension by the panel.

Where can I find technical details for Tachometers and Counters products?

A counter counts pulses; it is not a substitute for an hour meter that accumulates the machine's operating time or an electric meter that measures consumption in kWh.
