Timers & Counters

Timers, counters and process control components convert incoming signals to a display readout. They can be used as a straightforward process display or signal other devices to control an event upon reaching a preset value.

Timed events are measured using time counters. Timed events are displayed on a mechanical figure wheel or a timing hand or can be viewed on an LCD.

Programmable time formats include hours, minutes and seconds; they can increment or decrement to a preset or totalise without a preset function.

Counters register pulsed input signals and translate them to a digital readout. Totalising counters accumulate a count value in one direction only (adding); they are generally non-scaleable and do not signal other devices. Preset counters come with at least one output, providing a signal to other devices on reaching a preset value.

Preset counters, in most cases, are bi-directional (adding and subtracting) and programmable that feature scaling where incoming pulses are multiplied to represent a comparison between the sensing device, measured material or speed, and the display readout.

Several counter types are included within this range, some with and some without a preset function.

Counters can be mechanical without power, electrically powered, or can be self-powered by a lithium battery.

This section includes mechanical, electrical and electronic timers or counters, process indicators, rate meters, revolution counters, stroke counters and length measurement devices.
