OTT ecoLog 500 Groundwater Datalogger

The compact groundwater data logger OTT ecoLog 500 combines three features in one instrument: measurement, data storage and data transmission. The outstanding price-performance ratio is impressive - not only for qualities like longevity, precision and efficiency but also thanks to quick maintenance and comfortable handling.

Perfectly protected, all components fit into pipes from 2“. The state-of-the-art pressure probe is equipped with a rugged, ceramic-capacitive measuring cell, a precise temperature sensor and the data logger. The communication unit at the top end of the system holds batteries and data transfer components. The two units are connected with a Kevlar-reinforced cable with pressure compensation capillary.

The data telecommunication concept of GSM/GPRS-modem and antenna allows for great versatility (HTTP, FTP, SMS…). In addition to the measured data also alarm- and status messages can be transmitted.

A clearly structured operating program with online-help simplifies the configuration and data read-out on site. The infrared-interface of the communication unit is connected with the laptop via a special reading head; contact plugs which could corrode or deform don’t exist.

Thanks to the maintenance-friendly design, the battery, SIM-card and the desiccant capsule can be changed on site without any tools. A clever power concept makes the system stupendously energy-saving. Depending on the measurement- and transmission intervals, a lithium battery pack will last up to 10 years. This saves maintenance time and reduces data loss due to power cuts. Alkaline batteries might be used alternatively.

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.
