PRODUCTS ENCLOSURES & AIR MOVERS
FULLY WEARABLE STANDARD ELECTRONIC ENCLOSURES
Fully wearable standard electronic enclosures have been launched by OKW which enable wearers to use wireless electronics inconspicuously and without restriction of movement. Each BODY-CASE enclosure is supplied with two 18mm spring bars for fitting the wrist strap, enabling it to be worn like a
watch. However, with the optional fastening kit, it can also be hung around the neck on a lanyard, clipped to a belt/pocket or carried loose. BODY-CASE is available in one size measuring 55 x 46 x 17mm, and it can be specified either with or without a recessed top for a membrane keypad or product label. The cases can accommodate touchscreens, push buttons or voice-activated electronics; and power is supplied by round or button cells on the PCB or by a rechargeable battery with a copper loop for charging the device inductively. This offers protection levels of IP65 and IP67 and customising
options are available. Each case comprises three parts: a top section with PCB location bars; a bottom section with four pre-moulded drilling centres for use when fitting contact pins (drilling required); and a soft-touch matt sealing ring. Applications include mobile data recording and transmission;
tracking and monitoring; emergency call and notification; and bio-feedback sensors for healthcare, wellness and sports fitness. It can also be used for digital communications applications, stock and sales logging, safety engineering, measurement and control, automation, etc.

INTELLIGENT FAN TRAYS In Abu Dhabi, summer temperatures routinely exceed 40°C. So, Verotec has supplied Yokogawa with several hundred modified intelligent fan trays, destined for the new Umm Lulu development located 30km offshore. This is expected to produce up to 100,000 barrels of crude oil a day when fully operational in 2017. For this, the 1U 19in intelligent fans trays were selected because of their high airflow, low noise, low power consumption and controllability. The units had to be
modified to withstand the harsh operating conditions, yet be available on rapid delivery. As the atmosphere is salt-laden, even inside the control room, the fan trays’ PSU and control electronics were protected by a 50 micron polyurethane conformal coating that was third-party verified
as meeting the G3 Harsh requirements of ANSI/ISA S71.04-1985, Environmental Conditions for Process Measurement and Control Systems: Airborne Contaminants.
