Thermal cover PR‑7064 prevents heat flow between process and ambient surroundings. It helps maintain the sensor tip and the prism surface at process temperature and may reduce prism coating. Use thermal cover when the temperature difference between the process and the ambient is more than 30 °C (54 °F) or when the process temperature is over +60 °C (+140 °F).
To remove the thermal cover, first open the 2 velcro fasteners on the right. Then open the velcro fastener on the left, unwrap the cover underneath the sensor and then remove the cover.
