UM30-2 Sensor Features Adjustable Filter-Setting

SICK UK has added the UM30-2 series to its range of 30mm ultrasonic sensors. The UM30-2 series includes a filter-setting adjustment that enables the user to change between a high-security mode, which protects against false signal switching but has a slower update, and a fast response mode for highly dynamic applications that do not require such a high level of false switching security.

This allows the customer to fine tune the performance of the sensor, enabling the UM30-2 to be used in even more diverse applications. Another new feature is the Multiplex switching mode, which enables up to 10 UM30-2 sensors to be connected to measure large areas, with integrated phase switching to prevent mutual interference and false switching. Targets of different colours or even transparent materials, water and film present no difficulty.

Despite now being 25 per cent shorter than the original sensor (between 84 and 105mm long), the UM30-2's 30 to 8000mm operating range is one of the widest available for this class of sensor, covering applications from level sensing and product detection to crane and vehicle-collision control. The clear display indicates distance to target and larger buttons increase ease of set-up.

Digital or analogue output variants of the UM30-2 are available, with the analogue variants capable of producing 4-20mA or 0-10V at their output. Selection of analogue output type is either automatic - the sensor detects the impedance of the load at power up, or manual - via the intuitive menu structure. Such flexibility reduces the number of different models required to meet installation needs and therefore reduces inventory costs.

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.
