Enhanced Accuracy and Reliability in Harsh High-Temperature
Environments

Honeywell introduced its R300 Series Temperature Sensor for use in potential EGR (exhaust gas recirculation) applications where operating temperatures can reach 300 °C [572 °F]. The R300 Series Temperature Sensor features enhanced reliability, accuracy and responsiveness which helps optimize fuel economy and engine performance.

The purpose of an EGR system on an engine is to reduce NOx (nitrous oxide and nitrous dioxide) emissions by cooling and recirculating exhaust gas back into the engine. The R300 helps the EGR system optimize those NOx emission controls.

The R300 Series uses RTD (resistance temperature detector) technology and features a robust, stainless steel closed-tip design to enhance reliability in aggressive environments. It provides an excellent response time as demonstrated by validation testing required by the transportation industry. The R300 also features an integral connector.

The R300 Series Temperature Sensor expands Honeywell’s existing temperature probe product portfolio designed for the transportation industry, namely the ES110-, ES115- and ES120-Series. The R300 Series is designed for potential use in heavy duty vehicle engine (oil, coolant, fuel and air inlet temperature sensing) applications.

Finder has announced the new 10 Series light dependent relays, which have the ability to control lighting according to ambient light levels. These relays will be of particular interest to designers, specifiers and installers both of lighting and of lighting control systems, and will find applications in the automatic control of exterior lighting around factories, loading bays, schools, offices and similar areas where lighting is required for security or safety reasons during the hours of darkness.

There is a growing need to reduce energy consumption, maintenance and replacement costs by ensuring that essential exterior lighting is lit only during times when the ambient natural light falls below an acceptable level, and it is this requirement that the 10 Series has been developed to address.

The 10 Series relays feature an integral photoelectric sensor combined with innovative light feedback compensation circuitry designed by Finder, which prevents the controlled lighting from ‘hunting’ on and off due to the perceived increase in ambient light when lights are automatically turned on. This feedback capability is achieved by monitoring the effect of the controlled lighting over a ten-minute period, which ensures compatibility with slow starting gas discharge lamps. ON and OFF delay times are reduced to zero for the first three cycles, which aids set up and commissioning and reduces installation time.

The new family of relays includes both single-pole and two-pole output types rated at 16A, and also a miniature type, 10.51, with a single 12A output. The double output 16A 10.32 allows Live and Neutral switching, while model 10.41 has a single 16A NO output for Live switching.  All the relays in the series operate from either a 120V or 230V AC supply.

The ambient light switching level is adjustable in the range 1 – 80 lux, and the relays are capable of switching up to 2.3kW of incandescent or halogen lighting, allowing the switching behaviour to be optimised according to both the needs of the individual application and the physical location of the unit.

Finder has announced the 13.12 Call and Reset Relay, which is designed to activate an alarm at a remote point and provide local indication of activation. The relay will be of particular interest to designers and installers of attendant call systems in hospitals and care homes, and to contractors involved in the provision of facilities into residential and commercial buildings where occupants may need to call for assistance.

An ageing population is creating a growing demand for both short-term and long-term facilities providing care and supervision - hospitals, care homes, assisted living developments, hotels and similar premises - and the means to summon assistance in these facilities is a fundamental requirement. The 13.12 relay is a conveniently packaged product that addresses this need, and which can easily be installed in new buildings or retrofitted in existing sites.

The 13.12 features dual outputs, offering the facility for both a remote alarm signal and a local indication of activation to be activated simultaneously. Independent set and reset inputs provide flexibility in the location of activation and acknowledgement points. The relay output contacts are rated at 8A, which means that they are capable of directly switching incandescent lamp loads up to 800W. Set and reset inputs are both continuously rated, so that no damage is caused to the product if it is inadvertently left permanently activated. The relays are suitable for 35mm rail or panel mounting if an additional bracket is used. The length of the cable run between the set/reset points and the unit can be up to 100m, allowing multiple units to be placed in a convenient centrally located control panel for ease of maintenance and space saving.

The 13.12 relays are housed in a compact 17.5mm single unit width rail mounting enclosure.
