Q22 Specialty pH/ORP Sensors Resist Poisons

Analytical Technology has introduced the Q22 Specialty pH/ORP sensors, which allow for simple sensor replacement without the need for an entire system installation. In addition, the new sensors have been designed for use with all pH/ORP analysers and generic panel meters. Conventional pH/ORP sensors are based on an open reference system, which allows the reference elements and electrolytes to be in contact with the process. Chemicals diffuse into the reference chamber and contaminate the system, causing the reference potential to shift and the sensors to fail. As a result, more cleaning and calibration cycles are required, costing more time and money. Analytical Technology's Q22 Specialty pH/ORP sensors, whether universal or loop-powered, incorporate a glass reference-system, protecting the sensors from chemical poisons that destroy conventional pH/ORP sensors. The electrodes of Analytical Technology's Q22 Specialty pH/ORP sensors are customised and user-specified to ensure optimum measurement reliability and maximum sensor lifetime. An integral pre-amplifier is encapsulated in the body of the sensors, generating a low impedance signal output that ensures stable readings in harsh environments and maximises the distance between the sensor and the analyser. A large volume, dual junction, replaceable saltbridge maximises the in-service time of the sensors and allows for easy and inexpensive sensor regeneration. The sensor housings are made of durable materials that provide outstanding mechanical strength and chemical resistance.

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.
