Temperature controller saves stockholding and increases flexibility

Irtduatr No u velles de I "industrie Classification rules from Lloyd's register Lloyd's Register has published new classification rules covering cold stores, container terminals and processing plants. The new rules result from a major revision of those published in 1976. They take full account of LR's considerable experience gained during the past decade in the classification of refrigerated installations, especially in the Middle East. Their preparation has involved wide scale consultation with leading authorities in the refrigeration industry and they have been agreed by the industry. The rules reflect the latest practices and trends in the industry without compromising the safety, impartiality and high standards traditionally associated with LR classification. Their scope has been extended to include subjects not specifically dealt with before but which now need comprehensive classification guidance. For example, new chapters deal with floor construction and heating, aspects of building structural design, fire protection, acceptance trials, and system design pressure determination. Recommendations and guidance notes have been incorporated as appendices to the rules. These cover fees, thermal load calculations, refrigerant piping sizing, vapour barriers, services additional to classification, and process plant classification. The rules make provision, for the first time, for all types of refrigerated installations of processing plant to be built under survey with a suitable classification notation being assigned on completion. They also provide for the assignment of a notation to cover installations in which air refreshing arrangements are required. Lloyd's Register, 71 Fenchurch Street, London EC3M 4BS, UK.

by incorporating a host of features which make it the most advanced and flexible temperature controller available. The model E5CS offers on/off or PID control with autotuning and can be used in heating or cooling applications. Multi-range temperatures can be selected (between 50° and + 999 °) and operation can be set in degrees Centigrade or Farenheit to class 0.5 accuracy. Calibration is simple to achieve using the internally positioned switches which allow the setting of temperature ranges and a series of variable alarm points. Indication is given by 11 mm high matched bright Led's which show, process and set temperature, output states, and alarm conditions as well as displaying information for diagnostics. A useful aspect of the E5CS's set up procedure allows it to be field calibrated for system offset. Spot calibration for sensor error is also possible The temperature controller is equipped with an electronic locking mechanism to prevent on-site tampering. A secret coding device allows authorized engineers to adjust set or alarm points via the front panel. It will suit a range of process, plant and packaging applications and will help to reduce stocking levels by virtue of the device's multifunctionality.

M180H OEM miniprinter

Ardous environments suit mini printer Epson have launched the M18OH; an OEM mini shuttle printer mechanism capable of operating in extended temperatures and aimed at design engineers in the retail and ticketing industries. The M18OH combines fast, high quality print with a low power consumption and is suitable for automotive use in such applications as taximeters, and for ticketing machines working in arduous environments, such as car parks and open air terminals. The six print solenoids of the M180H give a text and graphics unidirectional print speed of 1.7 lines per second. This gives 144 dots per line on standard 57.5 mm wide, 24column paper which is fed automatically. The power consumption of the M 180H is very low (200 mA) and a 5 V supply facilitates easy battery operation. It can be driven from a serial or parallel interface using the BA180 control board, and is a compact size (91 x 46.9 x 15.8 mm).
