22 Gas Detection
Gas detection series simplifi es refrigerant safety compliance Bacharach announces the introduction of the MGS-400 Gas Detection Series for commercial and industrial refrigerant and gas leak detection applications.
The MGS-400 gas detectors support safety compliance inside of machinery rooms, mechanical equipment rooms, chiller plants, cold storage facilities and walk- in freezers by monitoring for dangerous refrigerant leaks for numerous gases including HFCs, HFOs, HCFCs, CO2
, and NH3 (ammonia). The ability to detect refrigerant leaks and quickly initiate alarm systems helps to protect personnel and achieve compliance with safety standards like ASHRAE 15, CSA-B52 and EN 378.
MGS-400 Gas Detectors are supported by a mobile app user interface, making confi guration, calibration, and maintenance simple and intuitive. Reducing commissioning and installation time, the MGS-400 delivers on effi ciency and cost savings while allowing for plug-and-play, pre-calibrated sensor installation and replacement in the fi eld. Using the mobile app and plug and play sensors, gas detectors are installed in signifi cantly less time, for example, 5 minutes vs 25 minutes per detector without training. Calibration certifi cates can be generated from the mobile app and sent by email or shared to cloud storage platforms.
The optional MGS-408 Gas Detection Controller supports up to eight sensor channels and enables a centralized alarm and power system. With Modbus connectivity, the controller integrates with any facility’s existing building management or automation system. The MGS-408 also connects with Bacharach’s MGS-
250 IR-based refrigerant monitor and the dual-sensor MGS-550, allowing for fl exibility of individual site requirements. Power and communication connectivity from the controller to all sensors can be done with a single cable in a daisy-chain design.

Figaro’s Ultra-compact Electrochemical-type Carbon Monoxide Sensor TGS5141 Features:
• Ultra-compact – 13.9mm in diameter x 5.0mm in thickness * Battery operable • High repeatability/selectivity to CO • Linear relationship between CO gas concentration and sensor output • Simple calibration • Long life • UL recognized component
• Meets UL2034, EN50291, and EN54-31 requirements Applications:
• Residential and commercial CO detectors • Fire detection
Figaro Engineering Inc. is pleased to announce its latest offering—the ultra-compact carbon monoxide sensor TGS5141.
Figaro’s TGS5141 is a battery operable electrochemical sensor which uses a unique electrolyte that eliminates the need for a water reservoir. It is much smaller than sensors requiring a liquid electrolyte. With its ultra-compact size, this sensor is the ideal choice for size-oriented applications such as portable CO detectors, small residential CO detectors, and multi-sensor fi re detectors. OEM customers will fi nd individual data printed on each sensor in bar code form, enabling users to skip the costly gas calibration process and allowing for individual sensor tracking.
This new sensor is now available.

New, high-end, mid-infrared range camera offers
superb performance in industrial and lab
settings Infratec’s new ImageIR® 9500 performs effectively in a wide variety of applications where tests in the mid infrared range are needed. These cameras can perform site surveillance including monitoring of fi re hazards in industrial settings such as waste and recycling plants and factories, fi nd the smallest temperature differences in landscapes, biotopes and labs, search electrical installations or high- voltage nets for dangerous hotspots among their almost endless range of capabilities.

The ImageIR® 9500 features a cooled FPA photon detector. This is based on highly sensitive mercury cadmium telluride (MCT) and has a 16:9 HD format with (1,280 x 720) IR pixels. Due to its high native geometrical resolution, even the smallest structures on the largest of objects can be analysed in detail. The combination with a high-performance microscopic lens enables the display of structures of up to 1.5 µm in size. Users save valuable time by reducing the number of required single recordings, while avoiding geometrical measurement errors.
InfraTec´s unique MicroScan function further enhances the camera’s effi ciency because geometrical resolution can be increased to 3.7 Megapixels in full-frame. Images of this quality show the measurement objects in extremely high resolution.
With such high levels of precision, the ImageIR® 9500 is ideally suited for use in scientifi c and research institutions, anywhere in the world. This camera offers thermal resolution of up to 0.025 K., and enables reliable detection of very small temperature differences on measurement objects and creates the criteria for creating noise-free thermal images. IR frame rates of up to 1.5 kHz in quarter-frame, together with extremely short integration times of only a few microseconds, enable users to analyse fast-running thermal processes.
Comparable to other infrared cameras of Infratec’s ImageIR® series, this model is also extremely fl exible to confi gure. The camera comes with latest detector linear cooler technology. Its modular design provides convenient retrofi tting with components such as motorised focus, internal high-speed shutters as well as motorised fi lter respective aperture wheels. This means that users can easily solve their measurement tasks – no matter what fi eld of application they are working in.
