With its advanced control capabilities and versatile configuration options, this unit is the ideal choice for maintaining product safety and process efficiency. At the heart of the AV-9900 is its Safety Thermal Limit Recorder (STLR) functionality. The unit can be programmed with up to 5 selectable diversion setpoints, with remote selection available as an option. Critical product temperature is monitored using a dual-element RTD sensor. The STLR continuously checks the sensor balance to guarantee failsafe operation.
