Vaisala PDT101 Cleanroom pressure transmitter

Vaisala PDT101 are high accuracy, low differential pressure transmitters.  With a focus on clean room monitoring, Vaisala PDT101 are designed to measure low “pascal” type pressure differentials with spans as low as ±60Pa.  Options include mA or V outputs to suit your building management system requirement and Fluidic also can integrate these within the Vaisala viewLinc monitoring system.  Vaisala viewLinc is an FDA CFR 21 pt 11 compliant data acquisition system – contact Fluidic for details.


Vaisala PDT101 differential pressure transmitters are DIN mountable.  Fluidic can supply these in a panel mount solution.  They come with factory calibration certificates as standard.  Span and zero is adjustable. Fluidic can also offer annual calibrations – in our workshop or at your site – to ensure best performance accuracy over the entire instrument lifespan.   These instruments are well suited to higher demand clean room environments, including pharmaceuticals and data centre control.
