TEMP/LEVEL CONTROLLER

Parker’s new
• Level Switch SCLSDI
• Temperature Switch SCTSDI
• Combined Level&Temperature Switch SCLTSDI
streamlines setup and operation by unifying configuration, visualization, and control. Easily parameterize setpoints, view measured values locally, manage switching outputs, and generate a scalable analog output proportional to the measured variable—all from one common platform.

Monitoring tanks becomes simpler and more powerful with integrated level and temperature functionality. The SCLTSDI combines the roles of a level and temperature switch, sensor, and indicator in a single, compact device. With fast response, high accuracy, and seamless IO‑Link integration, it delivers real-time visibility, configurable setpoints, and reliable control—streamlining commissioning, reducing wiring, and enabling plug‑and‑play connectivity. Individually configurable switching outputs and a scalable analog output support both modern and legacy architectures, while the clear local display provides at‑a‑glance status and diagnostics to keep your process safe and efficient.

Level
The position of the float is finely and continuously recorded and shown in the display in mm or inch. Because the level is continuously recorded, the danger of individual mechanical contacts no longer exists.

Therefore the operational reliability of the monitored plant is greatly increased. Using the selectable percent display, the full level is uniformly displayed for the users, independent of the tank shape. An offset can also be entered (difference from the sensor to the tank bottom) to give a realistic indication of the level from the tank bottom. Different uses can easily be implemented or corrected at a later date using the menu-driven level switching points. As the switching point no longer needs to be specified at the time of order, the versions of mechanical level switches required is reduced. The switching outputs can be individually set up. Naturally all the convenient switching functions are available: window, hysteresis function and open / close for level. With the optional analogue outputs, the level can be monitored easily with a controller.

Temperature
The temperature in the substance is detected using a sensor; it is then evaluated and constantly displayed. Thanks to the easy switching functions (e.g. switching windows), intelligent switching settings can be achieved that are not possible using a mechanical temperature switch. Normally the outputs for the normal temperature functions cooling on/off and shutdown are pre-installed as standard. The temperature thresholds were designed for standard oils. It is possible to adjust the temperature monitoring temperature limits (e.g. cooling and shutdown) for each output individually using the keys:
• On/off switching temperature limits
• NO/NC contact
• Hysteresis / window function
• Time delay and attenuation
With the optional analogue outputs, the temperature can be monitored easily with a controller.
