The new TO-39 infrared sensors range has a four times improved signal-to-noise (SNR) ratio because the characteristics of the patented thin-film PZT have been optimised for methane and hydrocarbon-specific wavelengths. It also features increased responsivity of 270,000V/W within the filter band.
Sensor elements are built into a low noise circuit that has an internal CMOS op amp, with a 10GΩ feedback resistor outputting a voltage signal centred around half the supply rail.
“Our latest high sensitivity, two channel methane (CH4) range combines all the industry-leading features of our existing products, including fast response, instant switch on, low power and thermal stability,” said Andrew Wallace, CEO at Pyreos. “This really brings a fast, reliable solution to customers designing products for hydrocarbon gas detection.”
The methane (CH4) variant in TO-39 analogue format is sampling now, and orders are being taken for digital SMD samples in a dual package.
Pyreos will be showing the new product at the Sensor and Test Show in Nuremberg, 25-27 June 2019, Hall 5 – stand 242.
