General Monitors Offers Hydrogen Gas Detector

General Monitors has launched the TS4000H intelligent hydrogen gas detector, designed to provide reliable monitoring for small hydrogen leaks in industrial and commercial facility environments. The TS4000H gas detector accurately detects hydrogen at 0-500ppm levels. It features a precision electrochemical hydrogen sensor that has a T90 response of less than 30 seconds and minimal zero shift across its operating environmental conditions.

Furthermore, it is unaffected by short-term exposure to hydrogen concentrations up to 50 per cent LEL. The TS4000H detector has many advanced functions, including 4-20mA output, 8A relays, Hart or Modbus communications, and a three-digit LED display that displays gas concentrations in ppm. The system also displays fault codes for troubleshooting and provides complete status to the control room. All of the electronics are contained within an explosion-proof housing so that gas sensor information can be processed at the sensor site.

The gas sensor may be remote mounted up to 2,000ft (610m) away from the electronics. The interface module's galvanically isolated, intrinsically safe design also supports sensor field replacement without special tools or hot-work permits. The TS4000H detector is said to be easy to install and calibrates by activating a magnetic switch and applying gas. It is suitable for a range of industries where hydrogen gas leaks are a hazard.

For worldwide application, the detector complies with Atex, CSA, CE, GOST, and is certified for use in SIL 2 environments. In addition to monitoring for low hydrogen levels, the TS4000H can be configured to detect a variety of other toxic gases including: ammonia, carbon monoxide, chlorine, chlorine dioxide, hydrogen chloride, hydrogen sulphide, nitric oxide, nitrogen dioxide, oxygen deficiency, ozone, and sulphur dioxide.

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.
