They are known for high quality and reliable products. They have standard and custom engineered gas ignition and temperature controls for many industries including HVAC, hydronics, etc.

Fenwal Controls – Gas ignition and temperature controls

“Series 08-02 bimetal disc thermostats feature current capacities up to 12A at 240VAC measuring .350″ in height. An optional epoxy seal provides additional protection against contamination.”

Fenwal Controls - Gas ignition and temperature controls

A snap-acting disc serves as the actuating element in these rugged, precision thermostats. As the temperature reaches the tamper-proof predetermined set point, the disc snaps to provide rapid, positive contact action minimizing radio frequency interference and ensuring high reliability.

These are Vibration and shock resistant and have Automatic reset. The factory preset temperature values can be ordered in the range of 35° to 350°F or 2° to 176°C.

They design and develop gas sensors and gas detection equipment. These are used in building safety, automotive, air quality and HVAC applications.

Figaro Engineering – Innovative Gas Sensing Technologies

In 1968 Figaro Engineering brought semiconductor gas sensors to the industry by their Research and Development Efforts. These are required to prevent hazard and health issues at Home and the Workplace.

Products include residential gas and carbon monoxide (CO) detectors, breath alcohol analyzers, carbon dioxide (CO2) monitoring systems. They have sensor to detect General air contaminants, Solvent vapors and Methane.

Figaro Engineering - Innovative Gas Sensing Technologies

TGS823 shown on the right side is a Alcohol Solvent vapors detector with a range 50 – 10,000ppm. Power Consumption is just 660mW and has a Ceramic base resistant to severe environments. Industrial usage

The sensing element of Figaro gas sensors is a tin dioxide (SnO2) semiconductor which has low conductivity in clean air. In the presence of a detectable gas, the sensor’s conductivity increases depending on the gas concentration in the air.

The product shown in the left is the NGM2611-E13 Methane Sensor with a 500 – 10,000ppm range and 280mW consumption. It is a Precalibrated module with TGS2611 and temperature compensation circuit for residential gas detectors. You can see more Featured Sensors from Figaro.
