Released for Production! JS8746 - Harsh Environment Temperature Sensor


Ensuring a temperature-controlled environment for transportation of goods by land, sea or air is of the utmost importance to guarantee that the merchandise does not deteriorate during shipment due to temperature. In many cases, such as medical products, the shipping companies have a statutory duty to demonstrate that the product has been kept within strict temperature limits. Failure to do so can lead to the write-off and destruction of large quantities of expensive product.

The marine environment is especially complex and susceptible to change; container ships are subject to the extremes of artic and tropical weather systems. Sea water is highly corrosive, containing large quantities of chlorides and sulfates. Ozone, ultraviolet sunlight (UV) and cleaning detergents provide additional degradation potential to exposed materials.

Highly Accelerated Corrosion Test (HACT)

Highly Accelerated Corrosion Test (HACT)Highly Accelerated Corrosion Test (HACT) was developed by Delta (DK) and has been accepted throughout the marine shippingmarket to demonstrate long-term performance of electrical equipment exposed to this environment. Each day of HACT testingequates to 1 year of marine environment exposure. The JS8746 has exceeded 14 days of testing, substantially outperformingcompetitor products. 

JS8746 - Harsh Environment Temperature Sensor

The JS8746 Harsh Environment Temperature Sensor has been designed to address all aspects of temperature measurement forThe JS8746 Harsh Environment Temperature Sensor has been designed to address all aspects of temperature measurement forHVAC control systems in the container-ship market. Employing materials and build standards that enhance the sensor’s ability towithstand water ingression and degradation by the marine environment, the sensor meets statutory requirements for temperaturemeasurement and performance expectations.
