Whether you use electronic, electromechanical, mechanical or pneumatic counters, the devices available have been designed to meet your requirements. Our range extends from mini-counters through to sophisticated, programmable control counters, multifunction counters, position displays, displays, tachometers and timers. Time counters display the duty cycle of installations, machines and appliances. They provide information on the expiry times of warranty periods, hours of use and the countdown to the next scheduled maintenance work. For use in time-dependent controllers, we also have a series of preset time counters in our product range. As a further complement, we can provide a series of time counters that offer versatile configuration options in an attractive, state-of-the-art design. Examples of typical applications: Maintenance interval counters, control of mixing quantities.
