Pyreos announces TO-39 quad detectors for multi-gas and flame detection


The performance of Pyreos single and dual channel TO-39 detectors in a compact quad channel TO-39 package

Pyreos has announced the launch of a new range of four channel (quad) pyroelectric detectors in TO-39 packaging.  These extend the capabilities of the successful Pyreos single and dual TO-39 range, which is used for anaesthesia, refrigerant detection, exhaust gases, carbon monoxide, carbon dioxide and hydrocarbons. The new TO quad devices pack four elements with the proven performance of the Pyreos single and dual channel range and build on the wide range of gases already available.

The new TO-39 quad range benefits from pixel areas five times larger than the previous range and delivers a much higher signal-to-noise (SNR) ratio. The product is mechanically simpler and more robust than competing products as it builds on all the fundamental benefits of the company’s thin-film pyroelectric technology, including simple construction, low vibration sensitivity and thermal stability.

“We’re seeing increasing customer requests for multi-gas detection in a wide range of new applications and have developed this extension of our product range in response,” said Andrew Wallace, CEO at Pyreos. “Using four channels instead of two, we can provide a more efficient multi-gas product for a single, concentrated IR beam.  This maximises infrared energy throughput onto the device and reduces sampling error due to spacing.  It makes the existing successful technology even more cost-effective for our customers.

Pre-orders are being taken for samples of the new TO-39 quad. Pyreos will be demonstrating its entire product range at the Sensor and Test Show in Nuremberg, 25-27 June 2019, Hall 5 – stand 242.
