Problem: My utility plant has lost thousands of dollars due to false shutdowns from failed temperature sensors. How do I know the difference between a failed sensor and a true alarm situation?
Solution: Use the SPA2 Programmable Alarm. Any of its two or four relay alarms can be programmed to trip on an “open sensor” without tripping the high-temperature warning or shutdown alarms. Sensor failures will not trip the process.
