Laureate™ Digital Stopwatch & Timer
Resolution to 0.2 µs for time measurement of single or cumulative events. Displays highly accurate rate based on 1 / time.
The Laureate stopwatch meter is designed to time single events, such as sporting events or processes, which produce start and stop pulses. It can also time the width of a single pulse. Highest resolution is 0.2 µs, since timing is achieved by counting 5.5 MHz clock pulses. For long intervals, the display is updated continuously during timing. Laureate™ stopwatch timers use the FR dual-channel signal conditioner and Standard counter main board.
Display. The event time (Item #1) may be displayed H, M or S format with six-digit resolution. The longest single-event timing interval is 999,999 hours. The highest resolution is 0.2 µs. The event time may also be displayed in HH.MM.SS clock format with 1 s resolution. The stopwatch display is updated during timing at a rate controlled by a gate time, up to 25/s. It is reset to zero when the next start pulse occurs. Accumulated time from multiple events (Item #2) is also tracked and may be displayed up to 999,999 hours.
The FR dual-channel signal conditioner board accepts inputs from proximity switches with PNP or NPN output, TTL or CMOS logic, magnetic pickups, contact closures, and other signals from 12 mV to 250 Vac. Jumper selections provide optimum operation for different sensor types and noise conditions. A built-in isolated 5, 10, or 24 Vdc excitation supply can power proximity switches and other sensors, and eliminate the need for an external power supply.
Digital filtering is selectable for electrically noisy environments, including a batch averaging filter and an adaptive moving average filter which provides a choice of 8 time constants from 80 ms to 9.6 s. When a significant change in signal level occurs, that filter adapts by briefly switching to the shortest time constant to follow the change, then reverts back to the selected time constant. In a selectable Auto filter mode, the filter time constant is automatically selected based on detected signal noise.
Designed for system use. Optional plug-in boards for communications and control include Ethernet and other serial communication boards, dual or quad relay boards, and single or dual isolated analog output boards. Laureates may be powered from 85-264 Vac or optionally from 12-32 Vac or 10-48 Vdc. The display is available with red or green LEDs. The 1/8 DIN case meets NEMA 4X (IP65) specifications from the front when panel mounted. Any setup functions and front panel keys can be locked out for simplified usage and security. All power and signal connections are via UL / VDE / CSA rated screw clamp plugs.
