The Clorius ER 2000 electronic controller is used for constant temperature control. It is suitable for all heating and cooling control systems. The controller is primarily intended for marine installations and other industrial applications – such as cooling water and lubricating oil installations, flow temperature control etc. Design The ER 2000 controller is designed for panel mounting. For an easy start-up, it has optimization for the automatic determination of favourable control parameters. The optimization starts when changing the set point or when switching over from manual mode to automatic control. The optimization can be disregarded. For easy operation, it has three keys – two for scrolling or changing values and an enter key. Two digital displays show the process variable and the setpoint. 3 LEDs indicate actuator opens, actuator closes and alarm. The controller can be switched from auto mode to manual mode. In manual mode, the actuator can be opened, closed or stopped in a certain position. Three different alarm settings are possible: Alarm at a deviation from the setpoint SP Alarm at a fixed limit value Alarm at leaving a band around the setpoint SP It can operate either as a three-position or as a two-position controller or analogue (4-20 mA) controller and has an adjustable proportional band, integral action time and derivative action time. Function The temperature input comes via a Pt 100 sensor with a single sensing element. The measured value of the controlled variable is compared with the setpoint value and adjusted via a PI or a PID control structure. The ER 2000 can act as either a heating controller, the actuator closes at rising temperature, or as a cooling controller, the actuator opens at rising temperature. The ER 2000 permits direct reading of the actual temperature value (PV), and it is secured from failure in the measuring circuit, i.e. the controller can be set to give either a closing, an opening, or remain in current position command in case of sensor short circuit or sensor break. The error message Err appears in the LED display PV.

The WIKA 990.30 diaphragm seal is a unique development for homogeniser machines in sanitary applications. This diaphragm seal is available with process connections in various designs and is thus suitable for all common measuring points. The diaphragm seal systems ensure reliable measurements, even with high loading through vibrations and pressure spikes. Mounting of the diaphragm seal to the measuring instrument may be made via a direct connection or a flexible capillary. For the material selection, WIKA offers a variety of solutions, in which the upper body of the diaphragm seal and the wetted parts can be made of identical or different materials.

The Clorius ER 2000-P controller is used for constant pressure control. It is suitable for all heating and cooling control systems.

The Clorius ER 3000e electric controller is used for constant temperature control. It is specially designed for large engine jacket cooling water systems where conventional single loop controllers cannot maintain a constant and precise temperature. The ER3000 controller operates with TWO sensor inputs. One Pt 100 sensor is placed at the outlet from the engine and one Pt 100 sensor with a built-in 4-20 mA transmitter is placed at the inlet to the engine. The measured values of the controlled variables are compared with the setpoint value and adjusted via a PI or a PID control structure. Design The ER 3000 controller is designed for panel mounting. For an easy start-up, it has optimization for the automatic determination of favourable control parameters. The optimization starts when changing the set point or when switching over from manual mode to automatic control. The optimization can be disregarded. For easy operation, it has four keys – two for scrolling or changing values, an enter key and a key for choosing manual or automatic control. Two digital displays show the process variable and the setpoint. 7 LEDs indicate alarm, the actuator opens, actuator closes, slave control, setpoint raising/lowering and manual mode. The controller can be switched from auto mode to manual mode. In manual mode, the actuator can be opened, closed or stopped in a certain position. Three different alarm settings are possible: Alarm at a deviation from the setpoint SP Alarm at a fixed limit value Alarm at leaving a band around the setpoint SP The 3 alarm settings include an alarm in case of a sensor fault. It can operate either as a three-position or as a two-position controller and has adjustable proportional band, integral action time and derivative action time.
