Frequency Transmitter Series 9146

9146 series Ex i- frequency transmitters monitor the speed of rotating parts on one or two channels, e.g. the speed of fans or centrifuges. The frequency measured at the intrinsically safe input (between 0.001 Hz and 20 kHz) is issued as a unit signal (0/4 mA to 20 mA) or processed by a frequency divider. In single-channel devices, these frequency transmitters check whether speeds have exceeded or fallen below the limit values.

  • Compact Ex i frequency transmitter for monitoring rotational speed in hazardous areas
  • Limit value analysis + frequency-current conversion + pulse divider function over a width of just 17.6 mm
  • Parameterization made easy by "ISpac Wizard" software
