Multifunction process calibrator for electrical signals Type EC 25


Product description

Possible areas of application Multifunction simulator Type EC 25

SIKA process calibrators have been developed for simple and flexible calibration and maintenance. Various tests can be performed in a single operation without having to change instruments. This saves time. SIKA multifunction process calibrators combine the functions of a wide range of individual devices into a single unit.

Main applications

  • Service, maintenance and repair
  • Quality assurance
  • Testing laboratories and research
  • Instrumentation and control
  • Process industry
  • Energy supply
  • Machine and apparatus engineering

Numerous other applications are also possible.



Steps and ramps
An automatic program is generated for periodic calls. The type of signal, duration and value are defined. Start delay, number of repetitions and a continuous linear increasing or decreasing characteristic can be individually programmed.

High-speed call
Signal values needed time and again are permanently or flexibly stored in the simulator and can be recalled quickly at the push of a button.
