Tyne - Model 7044 -Actuator Response Time Monitor
Tyne`s Response Time Monitor is designed to measure the actuator response time from `Start` signal to `Feed back`. It also provides an alarm when the response time is over the limit. The circuit is designed with a hardware logic integrated circuit. No software is used. The display comprises four 7-segment LEDs to display from 0.01s to 99.99s. The setting is established using BCD switches with displayed numbers. Once the unit detects a Start pulse, it starts to count until the Stop pulse is received. The count is compared to the setting of a digital comparator. Once the count has exceeded the setting, the alarm trips and sends the output to the terminals.
Tyne Engineering`s Response Time Monitor can be used for critical or safety-related actuator response monitoring or as a delay-on timer. An example application is for testing the response time of the vent panel opening in the Power House Emergency Venting System in Nuclear Power Plants.
