Time/Temp Profiling PID Controllers

Ideal for applications that change temperature over time, Watlow's agency approved time/temperature profiling (ramping) controllers are available with a broad range of industry standard I/O and communication options. All Watlow time/temperature profiling controllers are designed and manufactured to withstand harsh industrial environments.

Applications

Environmental chambers
Complex process furnaces
Semiconductor manufacturing
Processes needing data logging
Processes requiring slidewire control of valves or positions
Any process that changes variables over time

Watlow Series 981/982

Series 981/982 Series 981 (horizontal) and Series 982 (vertical) 1/8 DIN time/temperature profile controllers are among the easiest to use time/temp profile controllers. Both offer 4-file/24-step program capability or easy-to-use fixed set point operation.
