Temperature Measurement
Rhomberg is offering a range of Thermoline temperature controllers. The range offers complete temperature control with affordable, quality products in a variety of models, each incorporating a range of key features to suit customer requirements.
The top of the range Thermoline TC600 is a four-digit, dual display temperature controller with all the features required for precision temperature control. There are three types of control outputs: An 8 A relay output for direct switching of loads, solid-state drive for indirect switching of larger loads and analog outputs of 4 to 20 mA, 0 to 20 mA, 0 to 5 V and 0 to 10 V. Serial data communication, allowing for remote configuration and monitoring in large industrial systems is available as an optional feature. It has three control modes: PID autotune allows the temperature controller to automatically adjust the P, I, D and anti-reset windup terms for minimal setpoint overshoot and fastest time to setpoint, on/off control for less critical applications and trip and recovery control mode with dual relay outputs to allow the independent control of two heating or cooling elements within one system.
The economic Thermoline TC515 has a three digit dual display and PID control with programmable P, I, D and anti-reset wind-up terms. The unit is keypad programmable for use with nine sensor types and offers a unique 16 h preselect timer for batch processing. This option is used to maintain the setpoint for the preselected time after which the process shuts down. Simultaneous display of the process and setpoint temperatures makes it easy to identify possible deviations.
The unit has two independent temperature alarms that can be used in twelve different modes. There is a choice to use an upper alarm level, a lower alarm level, or both. In addition, the 8 A relay output can be programmed for normally open or normally closed operation. An optional solid state relay output drive is also available. The features of the Thermoline TC515 are also incorporated in that of the TC600.
The low-cost Thermoline TC410 dual display temperature controller offers selectable PID control for accuracy and stability or on/off control for less sophisticated applications. The unit is factory programmable to accept nine sensor types.
Thermoline temperature controllers are easily installed and sensors are easily replaced, thanks to a reliable plug connector system. Easy set-up is provided through a user-friendly installation manual. Offered in 48 x 48 mm housing format, the product provides customers the benefit of interchangeability with other temperature controllers.
Thermoline has been designed, and is manufactured, in South Africa. The product is available country wide through a network of Rhomberg stockholding distributors.
