This is perhaps one of the toughest and most unique applications in the world that Turtle Tough provide an unrivalled and proven solution. Ammonium Nitrate applications involve high temperatures, aggressive mediums and the challenge of maintaining sensors that literally “freeze” with product the moment they are removed from the process, rendering the sensor useless. Our retractable pH Sensor is uniquely designed to interface with our hot-tap insertion valve retractable assembly. For this application, the modified hot-tap assembly includes a cross-flow dual port purge flush assembly allowing the sensor to be flushed with hot water on removal. This allows for safe and clean removal from the process dual-port-purge-flushunder pressure. Our hot-tap assemblies are a common feature in industries where direct access to the process is required inline or in-tank without interruption to service. The RADEL body plastics provide superior resilience to physical impact and high abrasion, while the high capacity KYNAR reference provides both chemical resistance and temperate resistance to 105°C with a high temperature option up to 150°C. Utilising our proprietary toughened glass the sensor is ideal for abrasive media as well as being capable of resisting acids or fluorides that may chemically attack the glass. Digital Smart Sensor Technology (DSST) This sensor is available with our digital smart sensor technology. This plug and play sensor has a quick connect fitting, eliminating the need for hard wiring to the analyser. On-board sensor memory allows the storage of calibration data, analyser configurations and sensor service history. This allows the sensor to be conveniently maintained and calibrated off-site or in the laboratory and pre-programmed with calibration data and analyser configurations. This stored information automatically uploads to the analyser upon connection and eliminates the need for any interaction with the analyser, greatly simplifying the change-out of sensors. A service log stored on the sensors is ideal for maintenance and quality assurance records.
