New Measurement Platform V3

New platform V3 „fastLine“ for gas sensors released

The new plat­form V3 fea­turing the opti­cal infrared gas mea­su­re­ment tech­ni­que is released after inten­si­ve test­ing for dual-chan­nel, dual-beam configuration.

The plat­form can be easi­ly adapt­ed for dif­fe­rent gases with dif­fe­rent con­cen­tra­ti­ons to be mea­su­red. Two or more gases can be mea­su­red in two mea­su­ring channels.

Extrem fast response times in milliseconds

The sen­sor was spe­ci­fi­cal­ly opti­mi­zed for extrem fast respon­se times for gas con­cen­tra­ti­on chan­ges of gases: Respon­se times of 150 msec or less are rea­ched at a gas flow as low as 0.5 L/min.

The­se sen­sors are the­r­e­fo­re ide­al for appli­ca­ti­ons in which it is neces­sa­ry to react quick­ly to gas chan­ges or to con­trol processes.

Precise measurement

Spe­ci­al­ly desi­gned gold optics direct a maxi­mum amount of IR light ener­gy through the mea­su­re­ment cells onto the sen­sors. This mini­mi­ses noi­se in the mea­su­re­ment signal and results in very high pre­cis­i­on and repea­ta­bi­li­ty of the mea­su­re­ments. This is achie­ved tog­e­ther with an extre­me­ly fast respon­se time.

Longterm stability

Thanks to the dual-beam tech­ni­que aging effects of the com­pon­ents can be com­pen­sa­ted. The sen­sor the­r­e­fo­re needs to be che­cked and adjus­ted much less fre­quent­ly with lon­ger cali­bra­ti­on intervals.

Gases

The plat­form was qua­li­fied first for car­bon mon­oxid CO and car­bon dioxid CO_2.

Addi­tio­nal gases to come are:

• Methan CH₄
• Sulp­hur hexa­fluo­ri­de SF₆
• Water vapor H₂O
• Nitrous oxid N₂O

Pressure- and temperature compensation

The gas con­cen­tra­ti­on mea­su­re­ments of both chan­nels are tem­pe­ra­tu­re and pres­su­re com­pen­sa­ted by default. On the one hand, this takes into account the pres­su­re den­si­ty accor­ding to the ide­al gas law, but also the chan­ge of phy­si­cal pro­per­ties of the gas due to pres­su­re and tem­pe­ra­tu­re depen­den­ci­es. This is why it can be con­side­red more of a gas ana­ly­ser than a gas sensor.

State-of-the-art electronics and sensors

The elec­tro­nics have been com­ple­te­ly rede­ve­lo­ped and are based on 24-bit tech­no­lo­gy. Com­mu­ni­ca­ti­on with the sen­sor is pos­si­ble via digi­tal RS-232 or RS-485 protocols.
