Corona Discharge
SDT
, http://www.sdt.be
When electrical stress ionizes air molecules around insulators a chemical reaction creates corrosion of metal parts and breaks down insulating compounds. High energy at the site of the corona discharge can cause serious damage to mechanical components and result in unexpected shutdowns and loss of service to virtually hundreds of thousands of customers. More serious is the possibility of fire or explosion. In an industrial plant, an electrical fire or explosion can have compounding effects dependant on other hazardous and toxic chemicals on site. The Ultrawave 170 Corona Tracer from SDT is designed specifically for electrical and insulation inspectors. It detects high frequency ultrasonic noise generated by electrical phenomena such as corona discharge, arcing, and tracking.

Steam traps / Condensate purge
SDT

The purpose of the purge is to separate phases A an B (liquid or gas condensates), to retain A and evacuate B. To control the purges, either a contact sensor or a magnetic sensor is used. The SDT 170 gives an instantaneous diagnosis of the operation of the purge and consequently, its cycle.

Bearing Lubrication Monitoring
SDT

Lubricators depend on Ultrasonic Detection to schedule greasing tasks. Over lubrication is silently killing you bearings. While too much grease is a crime with good intentions, its still a crime. Over lubricating damages bearing seals and builds pressure on the bearing. Contamination and increased temperature levels stress the bearing, shortening its normal life span.

Acoustic Tightness Control of Cars with Ultrasound
SDT
, http://www.sdt.be
Besides the passengers, luggage and pets, occasionally more annoying "guests" such as water, noise or dust sneak inside cars. At Citroën, the constant obsession to improve quality has resulted in the study of an efficient method to fight these uninvited guests. The secret is ultrasound technology.
