High Resolution Digital Floor Mounted Biaxial Tiltmeter

ETLG Inertial Aerosystems is introducing a high resolution digital, floor mounted biaxial tiltmeter manufactured by Applied Geomechanics. Designated the D711 it has NEMA 4X (IP65) accreditation allowing continuous exposure to moisture and inclement weather. This innovative tiltmeter is suitable for use in remote monitoring of minute movement in dams, structures large antennas and earthquake/volcanic zones.

3 models are available with full scale ranges of +/-.5º, +/- 5º degrees and a wide angle version of +/ 80º. The .5 degree model has a resolution of 1 microradian, and a repeatability of <4 microradian (static). Temperature range is -25 to 70º C (-10 to +100º C storage), with power requirements of 7 to 28 VDC at 27 mA and reverse polarity protection. Fully programmable with RS 232 and RS 485 output versions are available. The powerful firmware command set enables the user to control output data rates, data formats, sample averaging and other useful parameters. All are supplied with a graphical ZAGI user interface for windows computers.

This versatile tilt sensor maintains an absolute reference to gravity and unlike optical encoders does not need to be re initialised on start-up. The D711 bolts or clamps on to any surface and is well suited for areas of heavy traffic or vibration. The 12.7 mm holes in its three corners fit over the provided stainless steel studs.
Measuring 152 x 152 x 102 mm it weighs 1.4 kg. Each tiltmeter is provided with a 3 M hook-up cable and power supply for quick operation with a computer.

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.
