GE opts to have LED traffic signals meet higher standard

Ongoing random production unit tests by third-party certification firm Intertek will go beyond ITE standard. LED traffic signals from Lumination LLC, GE Consumer & Industrial's LED business, will now meet a comprehensive third-party certification for modules under the Intertek ETL Verified program. Production units of Lumination's GT1 brand of LED circular signals, arrows and pedestrian signals will be independently tested and evaluated using the latest industry standards published by the Institute of Transportation Engineers (ITE).
The new Intertek ETL Verified program goes beyond the minimum specs of other current third-party testing, which involved design qualification testing as defined under ITE Specifications, Section 6.4, requiring manufacturers to provide six proof-of-design modules that meet ITE Specifications.
The Intertek program involves an initial production facility audit and product benchmarking tests followed by a bi-annual facility audit and testing of two random samples of each SKU to ensure that production units are ITE compliant.
Section 6.3 Production Tests & Inspections of the ITE Specifications states that all lamps must undergo full production testing and inspection prior to shipping. All lamps must pass: luminous intensity requirements; power factor requirements; current consumption

Explosion Proof Temperature Sensor

The model of explosion-proof temperature sensor is wzpk-22i-b, which is made of stainless steel and has explosion-proof performance. If you want to conduct reliable temperature measurement, you first need to select the correct temperature instrument, that is, the temperature sensor. Thermocouple, thermistor, platinum resistance (RTD) and temperature IC are the most commonly used temperature sensors in testing.

The changes of physical parameters with temperature include expansion, resistance, capacitance, electromotive force, magnetic properties, frequency, optical characteristics, thermal noise and so on. With the development of production, new temperature sensors will continue to emerge.
