| Overview The Heaterstat takes temperature readings from heater models with a high temperature coefficient. You get accurate, efficient electronic control at prices comparable to thermostats. • Use with Minco Thermal-Clear™ and select Thermofoil™ heaters • Complete heating control system provides repeatable process control for worry-free and stable operation • Solid state on-off control with adjustable set point offers greater durability than electro-mechanical devices • Low power consumption — ideal for battery operated and vehicular devices • The small PCB mount package and less wiring saves space to reduce the footprint of your device • Mounting the Heaterstat separately allows the heater to be placed in tight spaces • Available factory matched calibration option allows for easy plug-and-play operation Operation The diagram below shows how the Heaterstat works. It periodically powers the heater just long enough to check resistance. If heater temperature is above setpoint (left side of graph), power shuts off within 0.010 seconds. If heater temperature is below setpoint, the Heaterstat leaves power on and continually reads resistance until element temperature reaches setpoint. It then shuts off and waits until time for the next pulse. Scan rate, the off-time between pulses, is factory set from 0.1 to 10 seconds (1 second is standard). Faster scans provide tighter control while slower scans conserve power during idle times (a 0.010 second pulse every 10 seconds takes only 0.1% of full-on power). |
