Fisherr 4196 Temperature Indicating

Controllers

Fisher 4196 temperature indicating controllers show

process temperature and set point on an easy‐to‐read

process scale. The controllers are used in industries

requiring accurate process monitoring and

temperature control.

A temperature bulb (figure 6) measures process

temperature. A 4196 controller then compares

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.

With the controller in the reverse‐acting mode, an increase in process temperature causes a decrease in output pressure. External Feedback Proportional‐Plus‐Reset Controllers (4196B) In controller override applications, this option minimizes reset windup in the secondary controller.

Product Bulletin 4196 Temperature Controllers 34.6:4196 May 2013 D200054X012 Installation In a typical installation, a 4196 temperature controller mounts on a pipestand. The capillary tube length determines the installation site. When installing a controller, the vent must point down. When the temperature bulb (dimensions shown in table 5 and figure 6) is used within a closed vessel, the bulb screws into a bushing (see figure 7) that penetrates the vessel.

Product Bulletin 34.6:4196 May 2013 Ordering Information Applications When ordering, specify: 4196 Temperature Controllers D200054X012 is used in a closed vessel. Refer to figure 7 for available sizes. Specify straight‐shank or tapered‐shank thermowell. Tapered‐shank thermowells, with their high strength‐to‐weight ratio, permit operation in higher process fluid velocities than do straight‐shank thermowells. 1. Description of the service 2.
