STI-94

Code: STI-94
  • pulse rate / period meter
  • rotational / linear speed control
  • revolution / movement period control
  • 0, 2 or 4 REL / OC outputs
  • analogue output: active or passive, power supply output: 24V DC
  • RS-485 / Modbus RTU
  • "over" signalling when the measuring range is exceeded
  • free configuration software S-Config
Description

The STI-94 tachometers are designed to control rotational or linear speed of moving objects. The device is also able to measure frequency. As an additional advantage the device can convert the rotational / linear speed into inverse values, and to display the single revolution period or process duration. The REL / OC control outputs can be programmed depending on the instantaneous value of rotational speed. Additionally the counter may be equipped with analogue outputs, according to the customer selection: active current output, passive isolated current output or active voltage output. The counter can be configured with the local keyboard or free S-Config software via the RS-485 communication port.
