Reader Reply Card no 36 New Industrial Sensor Brochure Released Trolex (UK) has published a brand new full colour, A4 brochure for its range of sensors and sensing systems for industry.
The new brochure shows the complete integrated command and control systems available from Trolex for gas detection, bulk material handling, machine monitoring, air/gas flow monitoring, process monitoring, gas leak detection, as well as plant-wide monitoring systems with SCADA interface, utilising the company’s range of functionally compatible sensors and controllers.
Where single products are required, the brochure gives details of the complete portfolio of Trolex products including fixed gas detectors, personal and portable gas detectors, sensors for monitoring flow, temperature, pressure, level and vibration, as well as switching sensors, indicators and flameproof connectors.
All products in the brochure guarantee integrative compatibility and are designed for cost-effective installation and maintenance. Specialists in supplying the highest safety category of Ex equipment that will remain functional and safe in atmospheres endangered by both toxic and flammable gas accumulations, Trolex works in every industry where safety is critical such as oil and gas, power, utilities, chemical and landfill.
Trolex has been working with safety-critical industries for over 50 years, providing high quality custom designed or built systems for environmental and condition monitoring. The products are independently accredited and are certified intrinsically safe for use in arduous locations.
Reader Reply Card no 37 Portable and Fixed Gas Detector Range Enhanced PPM Technology (UK) is pleased to announce a number of significant enhancements to their range of portable and fixed gas detection instruments.
Their new Wireless IAQ Profile PPMonitor is able to continuously monitor any Indoor Air Environment. The wireless technology enables real-time monitoring of almost any IAQ parameter including Temperature, Humidity and a wide range of toxic gases and compounds.
PPM Technology’s handheld Formaldehyde detectors the Formaldemeter™ htV and htV-m now offer improved performance and reliability; the instruments are able to accurately measure when extremely high concentrations of formaldehyde are present; this advance is due to innovation in technology; a new valve to regulate the supply of air into the instruments fuel cell.
The sampling mechanisms within our hand-held instruments previously were not suitable for continuous measurements of high concentrations of formaldehyde. We developed the new modified version of the instrument to enable the user to change the settings and monitor for much higher concentrations of Formaldehyde up to approximately 90ppm. This has been achieved through the introduction of a miniature solenoid valve, which ensures a closed system; this prevents formaldehyde from seeping into the sensor when sampling is not taking place. The valve has been designed inertly to measure Formaldehyde.
When the sample button is pressed the valve will open and will remain open for the same duration as the sampling period of the pump. The sample is collected through a length of tube. Previously only a finite amount could be sampled but now it is possible to have the pump run until the tube is filled with the same concentration as the area to be monitored and then take the sample directly from the tube. The Formaldemeter htv and htv-m can also be wirelessly connected to third party systems via the PPM Technology interface board (ifB). The interface board can be configured to give different voltage outputs; a 4–20mA current output and also gives a relay alarm output.

New Portable CH4, CO2 and CO Analysers
The IR4030 series is a new range of portable gas analysers for methane, carbon dioxide or carbon monoxide from Hitech Instruments (UK). The analysers are based on the already successful infrared sensors used in the wall mount IR600 range and incorporate all the features you would expect from a field instrument in a rugged case.
These are portable analysers designed for continuous measurement in a process environment - unlike the small, handheld instruments on the market. Thus the IR4030 is ideal as back-up to fixed instruments or for multi-site use. The rechargeable battery has been designed to last a full 8 hour shift.
In common with all Hitech analysers the IR4030 is supplied complete and ready to use – tube fittings, valves, filter, flowmeter, sensor, pump – everything you need in the basic price. The integral pump is particularly useful ensuring that correct flow can be achieved even in static atmospheres. A 0-1V programmable output is standard together with two indication alarms.

The analysers are available in a choice of % ranges for a variety of uses. Typical applications include biogas, composting, welding and gas mixing. However the technical support engineers at Hitech are always ready to offer advice and solutions for new applications.
