Products Technology File New multi-voltage long distance sensor
The AC/DC multi-voltage photoelectric sensors in Omron’s E3JK range now offer maximum sensing distances up to eight times greater than their predecessors following a comprehensive redesign. Other refinements include large robust sensitivity controls that make adjustment easy, and a light-on/dark-on switch that allows sensor operation to be instantly matched to the requirements of the application. Relay output versions of the new sensors offer universal operation from AC or DC supplies in the range 24V-240V, and are complemented by npn/pnp transistor output types suitable for use with DC supplies in the range 10V-30V.
All photoelectric sensors in the E3JK family are supplied in the widely used 50 x 50mm format, and have pre-wired connections with two metre leads. The family includes through beam models with sensing ranges up to 40m, retro-reflective models with ranges up to seven metres and diffuse reflective models with ranges up to 2.5m. Omron

project library that can be sorted and allows individual projects to be copied; and an integrated chiller configurator.
Rittal has introduced its updated RiTherm 6.2 software that allows climate control requirements to be quickly and easily calculated. RiTherm 6.2 includes generic component heat loss data and a heat loss calculator for busbars; an option to divide the required cool- ing output between several devices; a detailed breakdown of bayed enclosure suites; a saved
Enclosures can be selected from Rittal ranges or alterna- tively, the dimensions of bespoke cabinets can be entered manually. The heat dissipated by installed equipment can be input directly, calculated using actual measured enclosure internal and ambient temperatures or selected from a database of standard components. The interface guides the user to the most suitable, correctly dimen- sioned climate control solution. All evaluations are based on the requirements of IEC/TR3 60890 890 AMD 1 and DIN 3168 for
enclosure cooling units.
At the end of the calculation information is presented in the form of a detailed summary con- taining calculated enclosure sur- face area; radiant power emitted to the environment or absorbed from outside; resultant required cooling output; enclosure internal temper- ature excluding cooling measures and the proposed solution. Two versions of RiTherm 6.2 are available - an update to Therm 6.0 or later, or a 30 day trial - both of which may be downloaded from the Rittal web- site. The 30 day trial version can be upgraded to the full package. Rittal

Enter 220 New range of rotary load blower pumps
Busch (UK) has announced the launch of its new Tyr range of rotary lobe blower pumps that have been developed to deliver energy efficient vacuum and over pressure generation. The
Tyr range is suitable for a range of applications including pneumatic conveying, waste water aeration, soil remediation and low pressure compressed air. The company claims that the Tyr offers a 30% smaller footprint than equivalent products on the market, and the pump also features integral forklift access, which allows for easy handling and transportation when required. Improved product reliability is provided by front mounted condition gauges, indicating pressure, vacuum and gear box oil, which enable quick checks and maintenance. All connections, including inlet and outlet valves, ventilation and electrical, are also easy to access. The Tyr comes with two, tri-rotary lobes, which operate in opposite directions to provide six pulses following one turn. It offers quiet operation and reduced exhaust air, making it well suit- ed for applications such as pneumatic conveying. The pump is available with a flow range from 2 up to 73m3
/min (120 to 4,380m3 ing upon the installed motor. Other benefits of the range include the ability to work with variable speed control, a centrifugal ventilator that provides a low,
stable temperature within the casing to ensure optimum operation, and vacuum/pressure safety valves that secure the pump against overload. There is also a range of accessories available, and also featured is an unloading valve for soft starters, Y Star and Delta starters, and a temperature transmitter safety device is installed to provide monitoring at the gas discharge point. The complete cooling system with water pump provides problem-free connection to the blower and a kit is available for use in humid situations to prevent corrosion dur- ing standby. A discharge pulsation silencer provides further reductions on exhaust pulsation level by 10-12dB(A). Busch

The new Type 8315 single axis accelerometer from Kistler Instruments is well suited to low frequency applications, including automobile ride quality, wind tunnel investigations and aero- space testing where structural vibration and dynamics are used to assess performance, reliability and integrity parameters. The Type 8315 K-Beam capaci- tive MEMS accelerometer is well suited for use in R&D and OEM applications where precision, reli- ability and durability are demanded. Six measuring ranges from ±2g to ±200g are available with a frequency response of 0- 1kHz (0-250Hz for 2g), enclosed in a choice of hard anodised alu- minium or welded titanium hous- ings. The sensor design is optimised for low frequency appli- cations and a temperature output is provided for use where external temperature compensation of the output signal is required. The Type 8315 has a supply voltage range of 5-50V DC and 6,000gpk shock rating combined with the availability of a tempera- ture output and integrated signal conditioning. A choice of adhe- sive, threaded stud and magnetic mounting bases and connection options facilitate installation. Kistler Instruments
