You did what? 🫨 Three years in seawater? 😱 On top of an oven in 30 °C? Sometimes curiosity takes you to interesting places. For our Product Manager, Henrik Kudsk, it is no different. Three years ago, he got a question from a partner in the maritime industry, if our short stroke sensor worked at sea. He decided to do an accelerated durability test test. Out of curiosity. Testing the boundries. Would it work? -and what would it look like? So here goes.... Compressor capacity sensors are used on large screw compressors often used on ships. Here they can be affected by sea water mist and that might harm the sensor. This simple accelerated test shows how the sensor is affected by a 5% NaCl solution partly immersed for 3 years at slightly elevated temperature approx. 30 °C.   The result? The electronic unit is still in operation, and the sensor emits 22 mA as it should. Both LED are in operation, but the push button is stock. The lid normally mounted has not been mounted. The aluminum housing has pitting corrosion, but it is not impacting functionality.     📢 Conclusion The sensor can be used in environments where seawater is present. However, the cover/lid over the push button should be mounted including the O-ring It is not pretty, but it still works 💪 What do you think?
