NT538 control unit promoted by altitude test (6,000 metres)
Our NT538 temperature control unit brilliantly passed the 6,000 metre altitude test set up by MATE, an independent company.
What does altitude testing on temperature control units consist of?
The altitude tests are designed to verified product reliability at elevated altitudes. This test has the purpose to verify the ability of the apparatus to resist during and after the exposure at atmospheric relative pressure equal to -54,11 (kPa), equivalent to 6000 meters altitude, according to the reference standard IEC60068-2-13:2021.
How was the altitude test carried out on our control unit?
Tecsystem provided N. 8 temperature sensors to simulate DUT operational conditions.
Mate srl provided 4 resistors wired in series mode between power supply and actuation ports of DUT:
• FAN1 (activation at 40°C),
• FAN2 (activation at 60°C),
• ALARM (activation at 80°C),
• TRIP (activation at 100°C),
• FAULT (normally close, to open contact energize the DUT)
Test Results
Under none of the test conditions were any defects found in the DUT. Even following the final visual inspection, NO changes in appearance or faults in the mechanical integrity of the control unit were detected.
Here is the test procedure in detail.
