The VQ500 gas sensor series
2015-12-21 07:26:01, Angst+Pfister Sensors and Power AG With the VQ500 series, SGX Sensortech introduces a comprehensive range of fully certified, explosion-proof miniature sensor heads with a high quality pellistor pair and low power consumption. The sensor heads have been optimized for detecting highly flammable gases or percent volume concentrations of gases in thermal mode. Their profile matches that of contemporary, miniature electrochemical cells, making them ideal for use in portable instruments.
The VQ500 series includes specific sensors capable of detecting most flammable gases, vapors, as well as ammonium hydroxide (VQ547TS) at the explosion limit. The VQ546M and VQ546MR versions, which use thermal conduction, can display most gases with thermal conductivities other than air in percent volume concentrations. The VQ548ZD/W and VQ549ZD/W versions have been temperature tested during manufacture to confirm that their temperature performance is in accordance with the data sheet, thus ensuring compliance with the various performance standards applicable in the mining industry (Group 1). For its part, the VQ548ZD-S version offers increased stability thanks to additional "burn-in".
