Business profile
While level crossing safety is an obvious example of a railway associated hazard, the dangers caused by faulty trackside and train borne equipment as a result of ingress protection failure may be less apparent.
Sensitive electronic equipment located outdoors must be housed in enclosures that offer protection against a number of hazards such as water ingression. Insects and dust can affect its operational capabilities as well as obvious factors such as vandalism. Bernstein offers a wide range of IP68-rated, lockable enclosures that can be customised to meet specific requirements.
Having taken on board the industry- wide problem of negative pressure, high humidity and/or condensation inside enclosures, which can compromise ingress protection, Bernstein now offers enclosures with a ventilation gland. The gland creates continuous ventilation and pressure equilibrium, while maintaining the enclosure’s designed ingress protection level. The dual advantage of the system is that it prevents enclosures from flooding in the most demanding operating environments, protecting both trackside and train borne equipment. Emms continues: ‘As well as developing new technologies such as
SafeGate, we are constantly looking at ways to improve our existing products to ensure they meet the changing needs of industry. The increased speed and capacity generated by HS2 will bring its own specific set of requirements to the industry – Bernstein is committed to a strategic R&D programme to ensure the UK’s rail network is amongst the safest in the world.’
Another area of innovation for the company focuses on reliable train door closure. By taking the industry problem of doors failing to close securely if the closure mechanism fails when only one door is monitored, Bernstein came up with the idea of a secondary monitoring switch with a special actuator (from the
Bernstein GC range) for the slave door. Limit Switches from the GC range have been used extensively in the rail industry for more than a decade and have never failed.
Bernstein is a member of the Rail Alliance and offers a dedicated product range specifically designed for rail applications including components for level crossing safety, sensors that detect if clothing is caught in a closing train door or IP68 rated trackside enclosures. Emms adds: ‘Detection, control and protection are pivotal to everything the company does.’ •
