Pneumatic Temperature Controllers
Pneumatic temperature controllers compare process temperature with an operator- adjusted set point. The controller delivers a pneumatic signal to a control element. The control element changes the process temperature toward the set point. Controller types are available for proportional-only, proportional-plus-reset, proportional-plus-reset-plus- rate, and differential gap for on-off control.
 | The 4156K and 4166K temperature controllers provide rugged and economical solutions to temperature control in many applications, particularly in the chemical and oil production industries. |
 | 4196 temperature indicating controllers, used in industries requiring accurate process monitoring and temperature control, show process temperature and set point on an easy-to-read process scale. |
