The first of a new generation of innovative temperature measurement and control
solutions by Lake Shore, the Model 336 temperature controller comes standard
equipped with many advanced features promised to deliver the functionality and
reliable service you’ve come to expect from the world leader in cryogenic thermome-
try. The Model 336 is the only temperature controller available with four sensor
inputs, four control outputs, and 150 W of low noise heater power. Two independent
heater outputs providing 100 W and 50 W can be associated with any of the four sen-
sor inputs and programmed for closed loop temperature control in proportional-inte-
gral-derivative (PID) mode. The improved autotuning feature of the Model 336 can be
used to automatically collect PID parameters, so you spend less time tuning your con-
troller and more time conducting experiments.
The Model 336 supports the industry’s most advanced line of cryogenic temperature
sensors as manufactured by Lake Shore, including diodes, resistance temperature
detectors (RTDs) and thermocouples. The controller’s zone tuning feature allows you
to measure and control temperatures seamlessly from 300 mK to over 1,500 K by
automatically switching temperature sensor inputs when your temperature range
goes beyond the usable range of a given sensor. You’ll never again have to be con-
cerned with temperature sensor over or under errors and measurement continuity
issues. Alarms, relays, and ±10 V analog voltage outputs are available to help auto-
mate secondary control functions.
