The 4196 temperature indicating controllers show process temperature and set point on an easy-to-read process scale. These controllers are used in industries requiring accurate process monitoring and temperature control. A temperature bulb measures process temperature. The 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.


Features & Benefits
Easy Maintenance—Simple design allows fast, easy maintenance and minimal spare parts inventory.
Easy Adjustment—Adjusting the set point, adjusting the zero and span of the process pointer, and switching between direct and reverse action are accomplished quickly and without special tools. Also, no interaction occurs when the set point and proportional band are adjusted.
Vibration Resistance—The simple design and low mass of internal parts allow the controller to withstand the vibrations found in most plant environments.
Highly Visible Display—Two red pointers on a 114 mm (4-1/2 inch), white-on-black scale show process temperature and deviation from set point at a glance. Two other gauges monitor supply and output pressures.
Low Air Consumption—The relay and nozzle design reduces steady-state air consumption to as low as 0.09 normal m3/h (3.5 scfh).
Corrosion Resistance—Tough plastic housing resists corrosive environments. Internal constructions are available to resist corrosive supply pressure media such as sour gas.
