Liquiline Transmitter Measures Six Parameters

The Liquiline M CM442 multi-parameter analytical transmitter with Memosens digital sensors from Endress and Hauser is said to reduce inventory and stock handling and minimise costs. The CM442 retains technology familiar to users of the company's previous Liquiline M transmitters, such as user-friendly operation, easy-to-read display and robust housings. In addition, the transmitter has the additional advantage of being suitable for use with pH, ORP, conductivity, DO, turbidity and nitrate sensors.

The Liquiline/Memosens system is available in its most basic form as a two-sensor input, single alarm relay safe area solution, but users can easily expand the system with additional inputs and alarms. Endress and Hauser said standardisation and uniformity are also key strengths of the Liquiline systems. Achieved by implementing the digital Memosens protocol into the fixed cable sensors, all sensors now use the same standardised protocol for total data and mechanical interface compatibility and increased process safety.

When used together, any combination of different types of digital sensors, cables, holders and assemblies results in a measurement solution tailored to the user's requirements. This modular concept means that Endress and Hauser devices are easily adapted to different applications and requirements, giving more flexibility across the plant. Based on Memosens digital technology, all sensors can be pre-calibrated under laboratory conditions.

Featuring automatic sensor recognition, commissioning and maintenance tasks are simplified - both sensor and electronics replacement is said to be quick and easy, maximising operational capacity. In addition, if there is a problem with a process, Liquiline will notify users immediately via its automated alarm signal and red display. Process interruptions are minimised through the clear failure description and menu-guided instructions.

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.
