Compact Loggers Provide High-Capacity Data Storage

Spacelogger serial data loggers from Richard Paul Russell are standalone units offering high-capacity data storage in a compact, economical package. There are currently two standard units on the market - Textlogger and Windlogger - but the company also produces customised models for a number of OEM clients. With low power consumption and no requirement for PC hook-up, the loggers are suitable for remote logging applications.

ASCII data is stored on a removable mobile memory card (MMC) to facilitate data transfer. Spaceloggers add dedicated data-logging functions to equipment and sensors outputting RS232. The loggers are said to be simple to use and set up; no special PC software is required. Other features include: up to 2Gb of storage; low power consumption; a selectable baud rate; and an optional RS232 output of incoming data stream during recording. The Textlogger is a universal serial data recorder supporting a range of ASCII text logging applications from RS232-compatible data sources.

All received data is stored, unmodified, in a .txt file. The Textlogger is suitable for any application where an RS232 printer has typically been used but where a more convenient method of data logging is required. It enables data to be accessed electronically and to be easily analysed, according to the company. The Textlogger records data from any equipment or device with an RS232 output, such as load cells, scales and other batch weighing equipment; metering equipment, counters and sensors; new equipment testing and validation by research-and-development, laboratory and test departments; Autoclaves, washer disinfectors and analysers; and other equipment requiring the record keeping of operating cycles.

The Windlogger samples data from anemometers and other sensors with a single serial output. Configurable for a range of sensors, the baud rate and the identifying start and end characters that define each ASCII sentence to be logged may be selected. By using an appropriate signal converter, a sensor with RS422/RS485 output is also compatible. The Windlogger provides the date and time stamping of data. Data is stored in .csv format files, compatible with all spreadsheet programs, so no special software is required.

The Windlogger offers a solution for wind site surveys; a NMEA sensor including GPS data logging; remote-sensor data sampling and time stamping; and the data acquisition of site environmental conditions for health-and-safety and downtime records.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
