January 25 Webinar
Fleet and Fixed Asset Management Using Switch and Sensor Technology
Honeywell Sensing and Control is pleased to announce the next Webinar in its series. Join us for a one-hour presentation discussing switch and sensor-based systems to facilitate asset management of both moving and fixed property. Hear how Honeywell engineers are integrating RFID and similar technologies into switching and sensing systems for OEMs to build data/parameters tracking and storage capabilities into their own products. These systems can help to improve asset utilization, minimize downtime and enhance overall efficiency – from vehicle fleets to assembly line equipment.

Linear position sensor drives emission technology
Sensing and control technologies are playing an ever more important role in optimizing the powertrain components that help automotive manufacturers meet emission obligations.
In the case of turbocharging, this means developing sensing units for actuation that not only feed data to engine control modules, but also accommodate turbo operating speeds of up to 300000 rpm and temperatures in excess of 1100º C.
The pneumatic actuator uses engine vacuum to adjust the angle of the turbo blades in the exhaust gas flow, thus controlling the speed that the turbo is allowed to spin.
At lower engine rpm there is less exhaust gas available to provide power to the turbo and the vanes need to be more closed to capture the flow. The Honeywell linear position sensor integrates into the pneumatic actuator assembly and provides
virtually instantaneous feedback to the engine control module in order to regulate the angle of the turbo blades and thus provide more precise control of turbo speed.
Honeywell Sensing and Control and Turbo Technologies have been working together since early 2003 to develop technologies aimed at meeting the future requirements of commercial vehicle and passenger car manufacturers, resulting in the first Honeywell linear position sensor application for a 2007 pneumatically actuated turbocharger for use on a European 2.0 liter engine program.
Sharing expertise and knowledge, the two Honeywell businesses present turbo sensing and control strategies to car and truck manufacturers around the world. This collaboration resulted in the selection of a Honeywell linear position sensor for a European 1.6 liter engine program.
The joint expertise allows Honeywell to help customers utilize the maximum advantage from turbocharging. The performance curves are attracting interest in Europe, the U.S. and Asia among customers who recognize the potential of utilizing Honeywell synergies in addressing pressing issues of emission control.

Complete torque measurement through TMS 9000
When conditions are tough, Honeywell’s Lebow torque sensors are tougher. For years, sensor operators in varied applications have acknowledged the
superior accuracy, durability and quality built into each Lebow sensor. The advanced generation of rotary transformer sensors, a non-contact telemetry system, is designed to operate in the digital domain for enhanced accuracy and versatility. All set-up and output is controlled through computer software. More than a stand-alone sensor, the TMS 9000 is a complete torque measurement system.

Q: Why do I need Positive Break switches for my safety application?
A:
 All safety switches (key operated interlocks, safety switches, safety rope pull products) feature positive break contacts on the Normally Closed circuit(s). (See note below.) These circuits are identified in literature by the positive break symbol shown above which is a circle with a left to right bold arrow in the centre of the circle. Positive break ensures that should the NC circuit be subjected to a fault current or voltage which causes the NC contacts to weld closed, then by applying pressure to the plunger or pulling on the key or rotating the lever or pulling on the rope, the switch mechanism is designed to force apart the NC contacts, therefore breaking the weld. This ensures that an open circuit occurs even under an electrical fault condition. It can be usual practice to protect the safety NC circuit with a fuse of an appropriate rating for the control current being used however, if this additional security is shorted out or bypassed, positive break ensures that the contacts will separate when required.
The positive break feature is specified within Chapter 3 of the Low Voltage Directive LVD EN60947-5-1, usually described as EN60947-5-1-3. The LVD gives general requirements for specifying the electrical current, voltage rating and life characteristics of Low Voltage Switchgear (such as safety switches and standard limit switches). What separates safety switches from standard switches is the incorporation of the optional chapter 3 of the LVD,
which describes the characteristics of positive operation.
