Parr 4843 dual element modular temperature controller
Start Saving with the PARR 4843 Dual Element Modular Temperature Controller. Various enhancement modules can be added to assist in monitoring and controlling the temperature, pressure and stirring speed in Parr reactors. The 4843 Controller is dual element, microprocessor based fully digital temperature control system offering PID control loops for both heating and cooling along with Ramp and Soak temperature profile programming.
Start Saving with the PARR 4843 Dual Element Modular Temperature Controller. The Series 4840 Dual Element Modular Controllers are offered in two different models from which the user can select either a programmable temperature controller or a cascade control system. Various enhancement modules can be added to assist in monitoring and controlling the temperature, pressure and stirring speed in Parr reactors. The 4843 Controller is dual element, microprocessor based fully digital temperature control system offering PID control loops for both heating and cooling along with Ramp and Soak temperature profile programming.
* TDM Tachometer Display Module
* This module provides a means for continuously monitoring the stirring speed in Parr reactors, offering a particularly valuable feature since all reactors are normally equipped with variable speed motors. It consists of a bright digital readout to be installed in the controller cabinet and connected to an optical wheel and sensor mounted on the driven pulley assembly in the overarm. The digital display will show the stirring speed with 1 rpm resolution and +/- 5 rpm accuracy. When ordering this option for field installation be sure to provide the model number and serial number of the reactor on which the tachometer is to be installed so that the proper hardware can be furnished.
* AMM Ammeter Display Module
* This module provides a means for continuously monitoring the current being drawn by the stirrer motor. Since the motor speed control will provide a constant stirring speed at any given setting, changes in the current drawn by the motor will correspond to changes in the viscosity of the reactants in the vessel. This will be a useful option for users who want to monitor the progress of a polymerization reaction in which there is a viscosity change as the reaction proceeds.
* This relay is rated for heater loads up to 25 amps.
* This control module drives the variable speed DC motors used in Parr series 4500, 5100, and 5500 reactors. A rheostat is provided on the front of the controller for setting the stirring speed. Potentiometers are provided on the control board to set the maximum stirring speed and the maximum current delivered to the meter.
* In addition to full power and shut off, this circuit allows the operator to select 50% power output for better control at lower operating temperatures.
* This relay interrupts power to the heater should an alarm condition be sensed in the primary control module or in the high temperature or pressure display modules.
* Up to four expansion modules can be installed and integrated in the controller.
* Sockets are provided for quick coupling of both the reactor heater and the solenoid valve module (optional) for control of cooling water.
* Switches, Fuses, Breakers and Connectors
* These are provided for full protection and easy operation of the reactor.
