Preset pneumatic counters are designed to count pneumatic pulses and resister them on a mechanical display; a pneumatic output on reaching a preset value is given and remains on until reset, used to signal other devices within a pneumatic system.
Pneumatic preset counters are a favourite industry device, constructed with durable plastic moulded bodies, often used for industrial machine applications where batch counting, ratio counting or dosing is an essential requirement of a process. They are intrinsically safe, commonly used in areas where no electrical power is permitted.
Using the push buttons on the front of the counter you set a preset value, white digits on a black background make it easy to read.
Pneumatic air pulses are either added or subtracted depending on the version selected. Adding versions have two rows of digits; the original preset value and process value are always visible, the counter starts from zero and counts up to a preset value, then a pneumatic output is generated. Subtracting versions have a single row of digits; a preset value reduces until it reaches zero, then a pneumatic output is generated.
Reset the device by either pressing the front reset button or by a pneumatic pulse signal to the rear of the counter, reset port Y.
