May 16, 2014, A new control platform for Sigma Systems’ cryogenically and mechanically cooled thermal chambers and plates supports testing of components, sensors, and PCBs involving temperature cycling from two to four points. The new TS Controller provides touch-screen and remote interfacing to set up and transfer thermal profiles, display data and trends, and log diagnostics.
Setting up test parameters (from -185 to +500°C) such as set points, ramp speed, hold time, probe source, auxiliary ports, and number of temperature loops is faster than with previous systems. Display status includes temperature data and trends for the device under test, the chamber, and set points. Diagnostics such as cryo valve usage, ambient temperature, chiller and blower runtimes, and enclosure temperature assist with maintaining system performance. An optional independent fail safe protects the unit under test from damage.
